Raspberry Pi 3 Model B+ on sale now at $35

Here’s a long post. We think you’ll find it interesting. If you don’t have time to read it all, we recommend you watch this video, which will fill you in with everything you need, and then head straight to the product page to fill yer boots. (We recommend the video anyway, even if you do have time for a long read. ‘Cos it’s fab.)

If you’ve been a Raspberry Pi watcher for a while now, you’ll have a bit of a feel for how we update our products. Just over two years ago, we released Raspberry Pi 3 Model B. This was our first 64-bit product, and our first product to feature integrated wireless connectivity. Since then, we’ve sold over nine million Raspberry Pi 3 units (we’ve sold 19 million Raspberry Pis in total), which have been put to work in schools, homes, offices and factories all over the globe.

Those Raspberry Pi watchers will know that we have a history of releasing improved versions of our products a couple of years into their lives. The first example was Raspberry Pi 1 Model B+, which added two additional USB ports, introduced our current form factor, and rolled up a variety of other feedback from the community. Raspberry Pi 2 didn’t get this treatment, of course, as it was superseded after only one year; but it feels like it’s high time that Raspberry Pi 3 received the “plus” treatment.

So, without further ado, Raspberry Pi 3 Model B+ is now on sale for $35 (the same price as the existing Raspberry Pi 3 Model B), featuring:

  • A 1.4GHz 64-bit quad-core ARM Cortex-A53 CPU
  • Dual-band 802.11ac wireless LAN and Bluetooth 4.2
  • Faster Ethernet (Gigabit Ethernet over USB 2.0)
  • Power-over-Ethernet support (with separate PoE HAT)
  • Improved PXE network and USB mass-storage booting
  • Improved thermal management

Alongside a 200MHz increase in peak CPU clock frequency, we have roughly three times the wired and wireless network throughput, and the ability to sustain high performance for much longer periods.

Behold the shiny

Raspberry Pi 3B+ is available to buy today from our network of Approved Resellers.

New features, new chips

Roger Thornton did the design work on this revision of the Raspberry Pi. Here, he and I have a chat about what’s new.

The new product is built around BCM2837B0, an updated version of the 64-bit Broadcom application processor used in Raspberry Pi 3B, which incorporates power integrity optimisations, and a heat spreader (that’s the shiny metal bit you can see in the photos). Together these allow us to reach higher clock frequencies (or to run at lower voltages to reduce power consumption), and to more accurately monitor and control the temperature of the chip.

Dual-band wireless LAN and Bluetooth are provided by the Cypress CYW43455 “combo” chip, connected to a Proant PCB antenna similar to the one used on Raspberry Pi Zero W. Compared to its predecessor, Raspberry Pi 3B+ delivers somewhat better performance in the 2.4GHz band, and far better performance in the 5GHz band, as demonstrated by these iperf results from LibreELEC developer Milhouse.

Tx bandwidth (Mb/s) Rx bandwidth (Mb/s)
Raspberry Pi 3B 35.7 35.6
Raspberry Pi 3B+ (2.4GHz) 46.7 46.3
Raspberry Pi 3B+ (5GHz) 102 102

The wireless circuitry is encapsulated under a metal shield, rather fetchingly embossed with our logo. This has allowed us to certify the entire board as a radio module under FCC rules, which in turn will significantly reduce the cost of conformance testing Raspberry Pi-based products.

We’ll be teaching metalwork next.

Previous Raspberry Pi devices have used the LAN951x family of chips, which combine a USB hub and 10/100 Ethernet controller. For Raspberry Pi 3B+, Microchip have supported us with an upgraded version, LAN7515, which supports Gigabit Ethernet. While the USB 2.0 connection to the application processor limits the available bandwidth, we still see roughly a threefold increase in throughput compared to Raspberry Pi 3B. Again, here are some typical iperf results.

Tx bandwidth (Mb/s) Rx bandwidth (Mb/s)
Raspberry Pi 3B 94.1 95.5
Raspberry Pi 3B+ 315 315

We use a magjack that supports Power over Ethernet (PoE), and bring the relevant signals to a new 4-pin header. We will shortly launch a PoE HAT which can generate the 5V necessary to power the Raspberry Pi from the 48V PoE supply.

There… are… four… pins!

Coming soon to a Raspberry Pi 3B+ near you

Raspberry Pi 3B was our first product to support PXE Ethernet boot. Testing it in the wild shook out a number of compatibility issues with particular switches and traffic environments. Gordon has rolled up fixes for all known issues into the BCM2837B0 boot ROM, and PXE boot is now enabled by default.

Clocking, voltages and thermals

The improved power integrity of the BCM2837B0 package, and the improved regulation accuracy of our new MaxLinear MxL7704 power management IC, have allowed us to tune our clocking and voltage rules for both better peak performance and longer-duration sustained performance.

Below 70°C, we use the improvements to increase the core frequency to 1.4GHz. Above 70°C, we drop to 1.2GHz, and use the improvements to decrease the core voltage, increasing the period of time before we reach our 80°C thermal throttle; the reduction in power consumption is such that many use cases will never reach the throttle. Like a modern smartphone, we treat the thermal mass of the device as a resource, to be spent carefully with the goal of optimising user experience.

This graph, courtesy of Gareth Halfacree, demonstrates that Raspberry Pi 3B+ runs faster and at a lower temperature for the duration of an eight‑minute quad‑core Sysbench CPU test.

Note that Raspberry Pi 3B+ does consume substantially more power than its predecessor. We strongly encourage you to use a high-quality 2.5A power supply, such as the official Raspberry Pi Universal Power Supply.


We’ll keep updating this list over the next couple of days, but here are a few to get you started.

Are you discontinuing earlier Raspberry Pi models?

No. We have a lot of industrial customers who will want to stick with the existing products for the time being. We’ll keep building these models for as long as there’s demand. Raspberry Pi 1B+, Raspberry Pi 2B, and Raspberry Pi 3B will continue to sell for $25, $35, and $35 respectively.

What about Model A+?

Raspberry Pi 1A+ continues to be the $20 entry-level “big” Raspberry Pi for the time being. We are considering the possibility of producing a Raspberry Pi 3A+ in due course.

What about the Compute Module?

CM1, CM3 and CM3L will continue to be available. We may offer versions of CM3 and CM3L with BCM2837B0 in due course, depending on customer demand.

Are you still using VideoCore?

Yes. VideoCore IV 3D is the only publicly-documented 3D graphics core for ARM‑based SoCs, and we want to make Raspberry Pi more open over time, not less.


A project like this requires a vast amount of focused work from a large team over an extended period. Particular credit is due to Roger Thornton, who designed the board and ran the exhaustive (and exhausting) RF compliance campaign, and to the team at the Sony UK Technology Centre in Pencoed, South Wales. A partial list of others who made major direct contributions to the BCM2837B0 chip program, CYW43455 integration, LAN7515 and MxL7704 developments, and Raspberry Pi 3B+ itself follows:

James Adams, David Armour, Jonathan Bell, Maria Blazquez, Jamie Brogan-Shaw, Mike Buffham, Rob Campling, Cindy Cao, Victor Carmon, KK Chan, Nick Chase, Nigel Cheetham, Scott Clark, Nigel Clift, Dominic Cobley, Peter Coyle, Jon Cronk, Di Dai, Kurt Dennis, David Doyle, Andrew Edwards, Phil Elwell, John Ferdinand, Doug Freegard, Ian Furlong, Shawn Guo, Philip Harrison, Jason Hicks, Stefan Ho, Andrew Hoare, Gordon Hollingworth, Tuomas Hollman, EikPei Hu, James Hughes, Andy Hulbert, Anand Jain, David John, Prasanna Kerekoppa, Shaik Labeeb, Trevor Latham, Steve Le, David Lee, David Lewsey, Sherman Li, Xizhe Li, Simon Long, Fu Luo Larson, Juan Martinez, Sandhya Menon, Ben Mercer, James Mills, Max Passell, Mark Perry, Eric Phiri, Ashwin Rao, Justin Rees, James Reilly, Matt Rowley, Akshaye Sama, Ian Saturley, Serge Schneider, Manuel Sedlmair, Shawn Shadburn, Veeresh Shivashimper, Graham Smith, Ben Stephens, Mike Stimson, Yuree Tchong, Stuart Thomson, John Wadsworth, Ian Watch, Sarah Williams, Jason Zhu.

It was worth waiting for

Alan Mc (Irish Framboise) avatar

Wow. Oh Hap-Pi Day! Onwards & Upwards Raspberry Pi. Nice surprise waking up this morning =oD Hope to quickly get my hands on one here in France. Bravo.

The Raspberry Pi Guy avatar

Great Pi Day news!

I’ve taken a look at the new Pi here: https://www.youtube.com/watch?v=0keOYRbsvxc

Andrew avatar

Just to clarify a point you made in your video about 5GHz wi-fi – 802.11ac is NOT required for 5GHz support. My old laptop, which doesn’t even support 802.11n (only a, b and g) will happily talk to my new broadband router in the 5GHz band using 802.11g. You can also do 802.11n on the 5GHz band.

Tomi avatar

It talks 802.11a at 5 GHz not 802.11g.

Kabelo Thomo avatar

Congratulations from the pi-top team, we are excited about the new features! Happy Pi Day!!!

Bozo Hudopisk avatar

Great job!

Louis Parkerson avatar

I want one… no I need one!

Spud Murphy avatar

Really waiting for them to add some eMMC storage like the Tinket Board, that would make the Pi the best value out there.

James Hughes avatar

That would increase the price too much for only a tiny benefit for the vast majority of Pi customers.

Gary Wood avatar

Yep, really need a version that includes storage this is the only reason im not buying any more pi’s until they do(i have 3 P1, P2, P2+).

aRBemo avatar

I looked into this but doesn’t odder much speed advantage over and SSD but I’ll grant you they’re more compact.

aRBemo avatar

offer not odder

W. H. Heydt avatar

Short answer…get a CM3 or a NEC “CM3-16”.

Spud Murphy avatar

Sorry, Tinker Board!

Peter Jones avatar

Great work guys. Thank you for this. I would have liked 2GB, but at this price point the Raspberry Pi is unbeatable!

Chad Kingsley avatar

Need more RAM.. With all the upgrades and improvements why not add more RAM. At lease 2GB would have been better that 1. Making it 64bit and not adding more RAM Just seems like a waste :( Don’t get me wrong, the new specs. are A++, and can think of many more projects, just please add more RAM to the next iteration. Thanks All and Happy Pi Day :)

James Hughes avatar

Not possible with this iteration of the SoC. 1GB is the limit. See Eben’s posts above.

Matze avatar

Is the black dot on the heat spreader a hole or is it just printed on it?
If it is a hole you probably can’t cover it with a heatsink, can you?

James Hughes avatar


wololo avatar

i read that u cant cover it with a heatsink bc they changed the cpu size. but i don’t know if it’s still necessary to cover it with an heatsink.

James Hughes avatar

Heatsinks will work fine, but the new thermal management means they are less necessary for most tasks.

js avatar

Got mine today, it’s definitely a hole.
Can’t easily tell if what I see through it is die or encapsulant.
I’m assuming it’s there to either allow for thermal expansion, or simply for filling underneath the heatspreader with encapsulant.

James Carroll avatar

I just happened to be up late and trolling on twitter when I saw the news. I hit up Pimoroni and ordered 2 of them before they could run out. One for Amibian and one for my Libreelec box. I wonder how much difference this will make on playing x265 video. Thanks for the update!

Rainer S. avatar


I would love to have hardware support for x265

James Hughes avatar

Software support is available.

Guenter Kreidl (gkreidl) avatar

Will the new firmware for the BCM2837B0 become also available as a Jessie upgrade? I’d like to replace my Pi2 systems with the 3B+, but for a number of reasons they still have to use Jessie.

Eben Upton avatar

The firmware should work with Jessie. I’m not sure we’ll be doing an “official” update though.

Guenter Kreidl (gkreidl) avatar

Please consider to make it available via apt-get upgrade. This would make it very easy to replace the boards of working Jessie systems

Simon Long avatar

We’re not supporting Jessie any more, so we won’t be releasing Jessie images or updating the Jessie apt repo. However, while we’ve not tested it, you should be able to apply the new firmware to a Jessie image by running rpi-update. I’d recommend taking a backup first…

Jonas avatar

Great work! I’m going to order one as soon as I finished writing this comment! Also I like the news about a 3A+, I suppose it will be able to act like an ethernet gadget like the Pi Zero? Will it also have Wifi/Bluetooth?

Eben Upton avatar

It’s not a well-defined product yet, but the assumption is that it would have some sort of wireless, and a single USB port that could be made to work in gadget mode (small issue about the OTG ID pin, but probably resolvable).

Mikael avatar

Is it passive or active PoE?

Phil avatar


Also, are you implementing PoE with a floating ground? I assume not given somebody is bound to attach the Pi to something with ground tied to Earth.

Riccardo Moretti avatar

is there a simple reset button on the POE 802.3 Af Hat?
and did you manage to find a wiring route path for the FM antenna ?

Andy avatar

A somewhat related question; The ‘reduced schematics’ do not, as far as I can tell, include the PoE header and connections.

Is that a mishap or a deliberate omission?

Alex avatar

How muuch will the PoE HAT cost?!

Jonathan Pallant avatar

Looks like a really nice set of improvements. Well done!

How gutted were you to not have it out two weeks ago? You must have been bursting to tell everyone in that Pi History round up blog :)

Eben Upton avatar

Would have been great, but the volumes weren’t there, so it would have been a paper launch.

James Hughes avatar

But, but, but……It’s Pi Day!

Charles Dibsdale avatar

Great news – thank you, what a wonderful achievement.

Marcin Zając avatar

2gb and 64-128 gb of internal storage and all computer classes in high schools across the planet will run raspbian. Just a small hint ;)

Hacker X avatar

The storage shouldn’t matter for computer classes at all. That is EXACTLY the kind of scenario that network booting is beautiful for.

The RAM really can’t be helped until they switch from videocore 4 to 5 because a single gigabyte is the maximum VC4 can address. And no you shouldn’t get your hopes up too far because there have been no official announcements that a switch is even in a roadmap anywhere. It is just a somewhat assumed thing that it will happen at some point when the silicon is ready at a price point that is right for the foundation.

In the meantime you can really accomplish an amazing amount of tasks with “only” 1 gig of RAM when you take out a lot of the bloat so many modern systems use just to make things pretty instead of adding functionality.

There are a lot of use that still have childlike wonder and a certain giddiness seeing how much hardware they keep throwing at us for 35 dollars. It isn’t all that long ago when you couldn’t even find a computer with a 64 bit CPU let alone a multicore one and even in the early 2000’s a gig of RAM on a desktop was a pretty big deal.

Go back a decade before that and I know from experience that a 33MHz 486 with 8MB of RAM and a 330 MB hard drive, a video card with 2 MB of RAM, a soundcard with 16 bit audio, a 2X CD-ROM (a big deal at the time), and a 17 inch CRT cost around 2,500 dollars. It was also the same approximate size and weight as a 5 or 6 year old child.

I mean really stop and think about it. This is a whole computer small enough to fit in a drive bay of a desktop.

Douglas avatar

To use a modern web browser, you need about 1.5 GB of RAM to view sites without video. An extra 512MB or RAM would make the Pi suitable for everyday use as a computer (if you’re using a USB hard drive).

Of course, I think the memory requirements of the likes of Firefox and Chrome are insane, but that’s just the way things are at the moment for browsers that support JavaScript/ECMAScript which the vast majority of sites require to function.

James Hughes avatar

I agree. Insane to require 1.5GB just to display a website.

Ton van Overbeek avatar

You need the Stretch release from 2018-03-13 for the B3+.
Previous releases do not work (result in 8 flashes after the rainbow screen).
(Thanks to PiSupply I have a review model)

Ober avatar

Great work and good improvements! Keep it up and I guess we will see Raspberry Pi 4 by next year?

JPW avatar

Great evolutionary change ! Love the etched metal bits as well. Faster networking (I presume) make this a good candidate for making WiFi hotspot / router projects. Nice one !

Eben Upton avatar

It’s a nice balanced design for wireless/wired bridge products now. I’m using one as a hotspot and wireless NAS, for which the USB 2.0 storage bandwidth is perfectly adequate.

Dan Tat avatar

This is a nice upgrade! Just wondering though… Since the gigabit ethernet is over USB 2.0, I’m assuming there is still only one USB bus right? So if I connect a USB hard drive and try streaming from the Pi over a wired network, it will cut the throughput in half, right?

James Hughes avatar

Not sure about half, but yes, the USB bandwidth is shared.

amin seraj avatar

I love you guys. thank you for you are.

Mostafa avatar

Very Good news. Does it support Windows 10 IOT Core as previous version of Raspberry pi 3?

Eben Upton avatar

Microsoft are working to add B+ support to IoT Core at the moment.

Jose Cerrejon avatar

Amazing! Enjoy the Pi day with a new RPi. Thank you all for made what the Maker word means.
@ulysess10 from your blog about the Pi in english/spanish http://misapuntesde.com

Tinker avatar

Still throttled by the USB2 bus though. Now if it had USB3, ethernet could be 1000Mb/s and SSD would work at a realistic speed and make a superb desktop machine. I know, it defeats the original objective of a simple machine for schools and the like.

Ruben De Smet avatar

If you want such a machine, the Odroid XU4 at 60$ does all of that.

Bruce Tulloch avatar

The eagle has landed. Well done guys!

Eben Upton avatar

Thanks Bruce. Appreciate the help.

nagisa avatar

So, you use this Broadcom chip to power Raspberry Pi, but is there anywhere datasheet containing the electrical properties of the chip?

You should not connect *any* peripheral to any of the pins without knowing the load these pins could sustain. And such information, which would otherwise be a part of the electrical specifications in the datasheet, doesn’t seem to be public.

Would you honour the warranty request if an user puts a 500mA load on a pin that can only sustain 50mA and fries the whole thing?

James Hughes avatar

The published datasheet contains the data you seem to think is missing.

nagisa avatar

Could you please link to the data sheet?

AndrewS avatar

There’s also http://www.scribd.com/doc/101830961 if you want even more details.

Riccardo Moretti avatar

Are the reset jumpers in place and soldered in?
I found it very difficult soldering those pins.

Eben Upton avatar

No, we have not fitted pins to the reset and power-enable holes.

Parsa avatar

Great news.
as I understand from this post, the Bluetooth chip has been replaced, am I right?

Eben Upton avatar

That’s correct. CYW43438 has been replaced with CYW43455.

Pradeep Madhavu avatar

Looking forward to getting this in India at the earliest.

Vdub avatar

Does this use a 5.1v or 5v power supply?

Gordon Hollingworth avatar

Use the Official Raspberry Pi power supply and you can’t go wrong…

Mark Daniels avatar

Hi Gordon, we can’t all use the official PSU in our industrial applications. My applications use a DIN rail mounted PSU rated at 5V 2A. I cannot use a plug-in PSU for compliance and engineering reasons. The general specification that we assume on 5V regulated rails is +/-5% and we expect all connected equipement to be able to accept this. TTL logic chips are similarly rated. It would be helpful if you could provide an official tolerance for the 5V supply to the Pi 3B+. Many thanks.

Eben Upton avatar

That’s useful feedback. Informally, what matters is the supply’s minimum voltage under high, and rapidly varying load. Limits:

– our voltage throttle cuts in and drops the CPU speed at 4.6V
– many USB devices need at least 4.5V
– our PMIC shuts down at 4V

So a very stable 4.75V supply is preferable to a poorly regulated 5.2V. The official power supply is “special” because it has a slightly boosted zero-load voltage, good regulation under varying load, and thick wire (I kid you not) to minimise cable losses.

Mark Daniels avatar

Thanks, Eben. You have provided the information that I need in our application and I am sure others will be pleased to see this. Perhaps it could be put on your site somewhere in the specs for the Pi.

I totally agree with your statements regarding the upper and lower values, but we aim for high (5.1 V) as the only cable we can get with a micro-USB plug fitted is rather thin! We keep it very short ;) I know what you mean about the thickness of the cable on the official PSU and wish we could get a better cable. I don’t suppose you could offer one?

AndrewS avatar

I’ve never done any tests or measurements, but these seem to work quite well https://www.amazon.co.uk/dp/B01GJIZT9I/

Bruce Tulloch avatar

Mark, if mounting them like this works for you, blades offer regulated supplies that meet the necessary specs:


Michael Horne avatar

Congratulations to all involved. It’s lovely to have the incremental upgrade to the 3, especially the improved CPU speed and wifi capabilities. :-)

Matt Hawkins avatar

Great news. The signs were all there! Once the shops all started doing “maintenance” on their websites I knew what was coming. I wrote a blog post and guessed the spec. The only thing I had to edit was the generous 2GB RAM I had added :)

Eben Upton avatar

I think 2GB of RAM at $35 will need to wait a while: RAM prices are incredibly high at the moment, and remain on an upward trajectory.

crumble avatar

Does this mean that there is no VC3 limit in the near future? Some people will pay more for a 4GB DDR 3/4 version ;)

Or are there other hardware limits as well? Like the power consumption?

Eben Upton avatar

There are limitations to the SoC architecture which cap us at 1GB. These are in theory fixable, but we’ve not prioritised that while RAM remains so expensive.

Dr Shaun Marrison avatar

So much for the environment…. QUOTE: “Note that Raspberry Pi 3B+ does consume substantially more power than its predecessor.”

Simon Long avatar

…in exchange for providing substantially more computing power to the user.

When you run a chip faster, it uses more power – that’s something of a physical law, and not really our fault!

James Hughes avatar

And note the Pi Zero is still available, which using the much less hungry bcm2835 processor, so you have an option the save the world right there.

Daniel avatar

Is there a way to lower the power consumption by programmatically setting a (substantially) lower core frequency? That would be green!

Eben Upton avatar

Yes. Some recent discussion of this topic here:


bensimmo avatar

It also needs to be taken in context.
*substantially more* on not exactly a lot for a computer 5V/<2A (<10W). Normally less than 1W in use with bits and bobs attached jsut now with an extra WiFi adaptor, keyboard and mouse, hdmi, SenseHat. Apt updating is averaging around 400mA, peaking at a bit over 500mA

Probably talking ~1W more max at the wall than before ?

My graphics card idles in my PC (budget GPU) at not much less than a fully loaded Pi stretch to the full and uses substantially more (6/7times) when in use.

GekkePrutser avatar

According to this it’s about 1W more idle and 2W more under load: https://www.raspberrypi.org/magpi/wp-content/uploads/2018/03/Raspberry-Pi-Benchmarks-Power-Draw.jpg which is a significant increase.

But yes the added speed is nice too.

Michael Macek avatar

Great news,
what about HW HEVC/h.265 support? This starting to be issue in countries with DVB-T2/HEVC – Germany, Czech Republic and other will follow (i.e. Italy and others)

James Hughes avatar

This is a point release, so a gradual improvement over the previous model. Putting in something like HEVC HW would require a new SoC. However, you can do software decode of HEVC, not sure of the maximum resolution possible though.

Eben Upton avatar

We can play much of the 1080p HEVC content that’s out in the wild at the moment (including 10-bit). Our “software” implementation has a generous dose of GPU-acceleration magic, and we’ve invested heavily in NEON optimisation.

Mike Kranidis avatar

IS there any good howto to follow in order to get H.265 playback running? What I need to do? What is the supporting player ( VLC? ) etc. Please guide me!

Eben Upton avatar

For maximum current HEVC performance, you’ll want Milhouse’s nightly Kodi builds here:


Shane Deconinck avatar

The throughput improvements are so valuable for us :)

Great work!

Martin avatar

Will it be possible to easily solder an u.FL connector to have an external WLAN/Bluetooth antenna?

Eben Upton avatar

I’m sure someone will find a way, but this isn’t something we could officially support, as it has serious effects on RF compliance.

Martin avatar

well on the zero w there’s at least a footprint and 0 ohm resistor available. from the pictures here I couldn’t verify if it’s the case for the 3B+

Richard Ahlquist avatar

After looking at the bottom picture from Farnell’s site I can tell you the point people were using before to mount U.FL connectors is gone. Will be interesting to see if someone comes up with an alternative.

Richard Ahlquist avatar

Ok did a bit of digging. The FCC docs show the on board antenna and if you ask me it looks like at U.FL could be mounted there. https://apps.fcc.gov/eas/GetApplicationAttachment.html?id=3777866 last page of the document.

Martin avatar

thanks Richard

unfortunately the linked document is not publicly available…

Raymond Richmond avatar

While I’m sure the RF compliance exercise would be a challenge it is high on our want list here at a University. We have challenging RF spaces and a mandated “single service” wireless infrastructure and the on-PCB antenna just doesn’t cut it. Being able to connect external antenna(e) would make the RPi much more enticing to many researchers and build clubs here.

James Hughes avatar

It simply isn’t going to happen. It’s a compliance nightmare, and would require us to supply a known tested antenna with every model. So expensive as well. The problem isn’t the Pi, it’s your environment.

Nuno Silva avatar

I’m sure it would be easy to find some very cheap antenna to provide as tested antenna… even if not a good one due to price, hardly it would be worst (and avoid internal interferences) than a pcb mounted antenna… and would give user the chance to replace it to a better one, if user wants!
Please re-think on this for the future… Thanks.

James Hughes avatar

Even a cheap antenna increases the cost of the Pi for everyone, even if the huge majority don’t need one. And the FCC compliance things really is a nightmare. I really cannot see it happening at least for the next few models.

Steve Davies avatar

Well done again!

Simplicity and common sense appear to be your ‘super powers’.

Fighting the urge of “I must have one… my precious”, expect to succumb soon.

Levente avatar

Will be able the new model to play UDH/4K videos (using e.g. Libreelec/Kodi)?

Eben Upton avatar

This is still a 1080p-class device. We can however play a lot of the 1080p HEVC content that’s out there.

Dave Semmelink avatar

I can’t wait to get one! Sadly, here in South Africa we have to wait for ICASA approval before they can be imported (legally). It took them 7 weeks to approve the Pi Zero W.

Just to be clear: the 300Mb/s Ethernet is only going to work with 1Gb/s switches and cable, right?

James Hughes avatar

It will work with switches UPTO that speed. So should be entirely backwards compatible, but will obviously run at the speed of the slowest switch.

Mike Redrobe avatar

Well it *is* a physical gigabit ethernet interface after all. It’s a bit coy calling it 330MBit just because it’s restricted by USB2. I guess that’s just to head off the trolls.

Eben Upton avatar

You read my mind :)

JacoR avatar

And we are still waiting for approval.

Neil Stoker avatar

Superb work Eben and co!

If I’ve got an up-to-date Jesse Lite SD card from a Pi3 B, will it work straight away if swapped into a B+?

Ton van Overbeek’s comment suggests it would if new enough. I’d got my image installed before the date he gave, but have updated it with apt-get as per here, so am guessing it would be fine, although confirmation would be much appreciated.

Eben Upton avatar

As Simon has said elsewhere in the comments, we’d expect you to be able to rpi-update a Jessie image with current B+-compatible firmware. Taking a backup first might be advisable.

Timo Albert avatar

How high is the heat spreader of the cpu in comparison to the metal shield of the wireless circuity?

Can i place a wide cooler on top of the cpu without interfering with the metal shield?

I’m using my Pi3 inside a case from WDLabs (the flat one) together with a 2TB usb hdd. The temperatures inside the case (hdd + RasPi) forced me to add a massive cooling solution and i had to add a copper plate to the CPU in order do get the actual cooler high enough above the circuit board to avoid any contact to the components on the board. cooling is still passive as the cooler is cut to fit in between 40pin header and all the other higher parts on the board.

If the heat spreader on the Pi3B+ CPU is high enough, i could go without a copper spacer…

James Hughes avatar

Thermal management is a LOT more efficient on the 3B+, using the PCB to move heat away from the processor as well as the cap. You *might* get away with no heatsink, but you will need to try it in your particular enclosure.

Timo Albert avatar

I appreciate your answer, but i doubt that i will get away without.

While the look of my WDLabs case is pretty nice, the thermal conditions are far from optimal. Air is trapped inside the case and a hdd and raspi under full load in summer heat up pretty quick. Only after applying a cooler taken from an old passive cooled graphics card i got rid of chronic overheating (at least of my RasPi, never checked hdd temp).

So my question remains: Is the cpu heat spreader higher than the wireless metal shield?

James Hughes avatar

Quick look, they appear to be the same height. Note that the PCB itself is now acting as a heatsink, and pumping heat down the wired connectors, so the thermal dissipation capability is much higher than the 3B.

This thermal design appears to work very well. A short power-on time (enough to do a quick goods-in check) and the USB sockets and ethernet socket shrouds are all warm to the touch. As are the GPIO pins. I guess they’re all acting as little radiators (convectors). Perhaps we won’t need a heatsink now in a standard case?

Thanks for the attention to detail!


Congragulations , it was a very exciting wait, very eager for it to come to India.:)

gregeric avatar

Looking at the hi-res photo clickable above, those vias look weird. Where’s the drill hole gone?

Gordon Hollingworth avatar

Boards with fricken lasers dude…

AndrewS avatar

…and along similar lines, what are the weird solder-blobs between the LAN7515 and the Ethernet socket?

PaulG avatar

Those sites would be for EMC/ESD diode packs. They give the ethernet PHI device added protection for any extreme pick-up on very long ethernet cables, or installations in noisy environments. I’m not familiar with the ethernet IC used here, but they were probably dropped for cost reasons. I’m more intrigued by the 45degree placement of these and the 1(!) capacitor on this board.

Louis Slabbert avatar

Looking forward to getting my hands on the new RPi 3b+ and the PoE HAT. Do you have an expected release date for the Power over Ethernet HAT? I can see a lot of uses when you don’t need to have a power socket nearby. It will even spark me to create videos again on my Youtube channel https://www.youtube.com/channel/UCculiYijgl1qXy6u51d6Ddw

Eben Upton avatar

We have all the components to build our first 20k in hand, so we’re literally just waiting for a manufacturing slot. Late April if we’re lucky, early to mid May more likely.

Luke Skaff avatar

I have read the limitations of faster preformance and less power from the processor is the 40nm node size which is very old. Why can’t they go to a smaller process?

James Hughes avatar

Moving to a new process is a painful and time consuming job, with no guarantee it will work without major changes to the silicon. So not a trivial task.

Eben has stated that we have pretty much reached the limit of the current process.

jax avatar

35 dollar?? Not here in the Netherlands. The cheapest I can find it is 49 dollar including shipping. Not worth it.

James Hughes avatar

Try some of the UK suppliers who will ship to the Netherlands, probably cheaper.

Helen Lynn avatar

It’s $35 plus local taxes and shipping, which of course vary quite a bit according to the locality; that said, the $49 total you mention is within pennies of the cost of a 3B+, shipped, in the UK.

jax avatar

I think I’ll wait till they are sold through AlieExpress. Buying there and having it shipped from China to the Netherlands is usually ( a lot) cheaper then having it send to me from the local warehouse down the street, so to speak.

James Hughes avatar

Cheaper because you are avoiding paying the tax you should be paying. There should be import duty applied, and whatever the Dutch equivalent of VAT is. Buying from Aliexpress is avoiding that, so you are in effect giving money to China (the profit) instead of your home country (profit and tax).

David avatar

The Dutch equivalent of VAT is VAT; however, as the Dutch have an even more creative approach to abbreviations than the French, they spell it BTW (Belasting Toegevoegde Waarde or Tax Added Value). Just in case you really wanted to know :-)

Michel avatar

Pollin in Germany sells it for 36,50 Euro. (ex shipping)

Douglas avatar

I was really hoping for a 2GB model… I honestly would have preferred more RAM over a faster network port and even a faster CPU… Bluetooth? Who is even using Bluetooth with these boards anyway? In any case, I’ll hold out until they have a new model with more RAM, and the same power demands as the original Pi 3 or Pi 2.

James Hughes avatar

Well, more RAM would require a new SoC, so rather out of the remit of this gradual upgrade.

People do use Bluetooth, you know the Pi3 has BT, don’t you, so that capability hasn’t changed.

As for power demands – if you want a faster processor, or more RAM, or faster networking, then the power requirements go up. You cannot change the laws of physics. So please don’t expect any future models to use less power. We are not Scotty.

Helen Lynn avatar

“Dammit, Jim, they’re engineers, not magicians.”

mjw avatar

RAM is incredibly expensive right now. And be thankful that these aren’t good for crypto-mining.

Michael avatar

Sorry a bit late with this comment. But I happily use bluetooth. My PI sits behind the TV and it’s running retro-pi+kodi, I control it using a PS3 bluetooth controller and it all works wonderfully. So I was happy to have the onboard bluetooth support. On previous PI models I was using a bluetooth dongle and setting it up was much more painful (same with having the onboard wifi, made things much easier).

Özgür avatar

“Who’s even using bluetooth with these boards anyway?”
-Tens of thousands of people all around the world, who are using Retropie/Recalbox on Raspberry Pi, with their bluetooth game controllers/joysticks?

Brendan avatar

Congrats on the new Pi 3+. I’m looking forward to using one in the future especially with the new 5Ghz Wi-Fi capabilities. Though i am wondering if there has been a solution to the issue of the Pi being unable to connected to an enterprise network i.e. one that requires account and password as i would love to use it in university but unfortunately cannot connect to the Wi-Fi.

pssc avatar

Pi’s can be connected to Eduroam WiFi(WPA2 peap with mschapv2) with username and password with a correct config.

fnord avatar

wpa-supplicant which Raspbian uses has no problems whatsoever connecting to a WPA2 Enterprise network, but you may have to configure it manually.

Jos avatar

“Improved PXE network and USB mass-storage booting”
What is improved about USB mass-storage booting?

Gordon Hollingworth avatar

Some of the fixes implemented for USB MSD booting and Ethernet booting got rolled into the bootrom. So should support a few more drives…

Piglet avatar

OOh! Does that mean I might finally be able to ditch the sd boot card and USB boot successfully directly from my WD Pi-Drive more often than the 1 in 20 times I get now?

AndrewS avatar

I’ve just successfully booted a fresh-out-of-the-box Pi 3B+ from a microSD card in a USB card-reader plugged into one of the Pi’s USB ports (with nothing in the Pi’s microSD card slot) :-) Very cool.

W. H. Heydt avatar

Odd…I’ve never had any problems booting a Pi3B (and now a Pi3B+) directly from a PiDrive. Indeed, within 5 minutes of opening the Pi3B+ box, I had it swapped into the case in place of a Pi3B and it booted right up from the PiDrive. (I did an update/upgrade cycle earlier in the day, so it was ready to go.)

What I need to test is to see what effect the new release of Raspbian has when setting up a CM3L in a WD SATA Adapter. That I’ve had problems with.

Peter Wenger avatar

So how much more power does it need, in which situation, and can the power usage be reduced if not a lot of CPU power is needed all the time?

zmlopez avatar

Great work with this design, I would look forward to see compute modules with this processor (and Wifi/BT included version), but…

“Yes. VideoCore IV 3D is the only publicly-documented 3D graphics core for ARM‑based SoCs, and we want to make Raspberry Pi more open over time, not less.”


There isn’t a datasheet of the processor, with a lot of features undocumented, like for example, DPI ports.

There isn’t even complete schematics of the board available. I don’t understand why: nobody could copy your product, as you don’t sell the processor to anyone.

James Hughes avatar

Full release of SoC datasheets is down to Broadcom, because they are the processor designers/manufacturers, not us. We do have a cut down one available. https://www.raspberrypi.org/documentation/hardware/raspberrypi/bcm2835/BCM2835-ARM-Peripherals.pdf

Partial schematics are available here. https://www.raspberrypi.org/documentation/hardware/raspberrypi/schematics/README.md

W. H. Heydt avatar

*Anyone* can buy the SoCs….so long as they are willing (and able) to commit to buying enough of them.

Jerry Wasinger avatar


Don Isenstadt avatar

Congratulations! Another great pi server for my pi zeros to connect to!

Bernardo avatar

Can you do also a Zero on Steroids? The Zero Form factor but with the processor and memory of the 3+

Callum Hendry avatar

You’ve gone and done it again…thanks Raspberry_Pi, you’ve made my π Day :) In context these are significant upgrades, but doing so without increase in price and not even trying to capitalise on what could have been marketed as Pi4 is a touch of class. Well done everyone! Bit out there but is there scope to build in the capacity for a wireless casting of a virtual desktop? Perhaps to a chromecast-esque dongle? Best of both worlds with a headless setup which still allows use of a graphical interface, and of course v portable.

James Hughes avatar

Casting is pretty much a SW issue. I sure some people have got Miracast working.

Callum Hendry avatar

Thanks, I’ll investigate Miracast. Ideally, what I would like ascertain if it’s possible to mirror the Pi desktop or video output to another device over WiFi? I appreciate that it is a software issue to a point, however is it not possible that if a receiver HDMI/USB dongle could receive the broadcasted visual, with a universal design to enable portability and out-of-the-box connectivity?

James Hughes avatar

Does VNC not do what you want? That can work over any sort of network connection.

roman1528 avatar

And NO IP.X / UF.L connector… you learned nothing in the past…

James Hughes avatar

Adding that connector would mean we have to supply an antenna otherwise we would not be able to get any sort of FCC compliance and would not be able to sell the product at all. Too expensive, a cost that would be passed on to huge numbers of people who simply don’t need the feature.

So, yes, we know exactly what we are doing. Adding that connector would be a terrible idea.

Ioannis Mourtsiadis avatar

The new Raspberry Pi 3 Model B+, except of all other things, has one, really very, very, important on my opinion – the Power ENable Input.
That means you can switch the Raspberry Pi ON/OFF, directly from your added PCB (i.e. in our case from PIco) without removing micro USB cable or adding an external switch to it. That make the Raspberry Pi 3 Model B+, a perfect device for embedded applications. Now, you can fit-in your hardware to the case and switch your application ON/OFF easy, and professionally.
Raspberry Pi Engineers, You are PERFECT designers !!
Warmest Regards

AndrewS avatar

Hmmm, looking at the reduced schematics it appears to be a Power ENable output? Looks like a simple voltage-divider means that it outputs 3.2V when the board is powered with 5V?

Ioannis Mourtsiadis avatar

No. Tested on real device. Check also the IC data-sheet used for the system powering
Warmest regards

Paulo avatar

But the possible switch off button through new POE will shutdown Pi correctly or just cut energy?

VeryNoob avatar

Can you tell us a little more about this? Do you just need to pull the PEN to ground to “cut the power”? This would be great. I can think of a few ways of using this. Something similar to the pi-supply or an ATTiny that reads a switch and a GPIO to determine when to cut power. Does work when powering via the GPIO, or just when powering via USB.

Martin P avatar

Why it still does not support decoder Format: H.264,H.265 ???
4K in the 21st century ….

James Hughes avatar

Full HW decode of H265 etc would require a new SoC and this is a point release rather than a entirely new Pi. However, the ARM cores are now capable of fairly decent decode in software.

Meanwhile, H264 still works and is a pretty decent format.

Martin P avatar

I will be interested in another raspberry when I support H.265

Gordon Hollingworth avatar

Already supports H265 1080P30, we’ve tested it with lots of available content and it all plays fine

Go for your life!

Adam F avatar

Could you clarify this? I assume this won’t work with omxplayer since it relies on hardware support (which the Pi doesn’t have for h265). Is there another way to play h265 media over HDMI on a *headless* Pi3?

James Hughes avatar

Yes, we are spending considerable time and money on optimising the H265 codec using HW blocks where we can, and NEON as much as possible. This means that the majority of HEVC stuff out there will work fine up to 1080p. Including 10bit. The work is still ongoing, but the latest overnight millhouse builds of Kodi have this codec in.

Farid avatar

Does it support windows 10 iot core ?

Does the GPU share in the speed boost? I don’t see any figures for its clock speed?

Eben Upton avatar

We’ve not increased the GPU clock at launch. We do have lots of margin though, so may do so (from 400/300 to 500/400) in due course.

Brian Beuken avatar

thanks for that, I would love to see a bit of a speed boost on the GPU but appreciate it will increase power and heat.

Can I also ask Eben, I know its a done deal now, but was there ever a possibility of increasing the number of cores for the GPU? I realise graphic programming is not high on most users list but it is on mine and I’d love to see Raspberry systems compete with some of the multi core GPU systems?

Abu Abdulla avatar

it is a welcome point release, thank you. i was looking for any improvement in the GPU if that will support faster rendering of the camera frames.

I hope to see also Pi 3A+ soon as it is the only small footprint replacement for the Pi 0w which is stuck with armv6

James Hughes avatar

I doubt there will be any improvements to the camera system for some time. What particularly is your issue?

Abu Abdulla avatar

sorry, i missed this.
there is certainly no issue, it is just in my wish list to stream from my camera a resolution more than the current limited 1080p due to H264 encoder limitation.

Richard Sierakowski avatar

This is an excellent and well considered evolutionary step in the RasPi series.


nmiller avatar

I think your temperature and frequency plot is labeled backwards.

Christian Nobel avatar

“Note that Raspberry Pi 3B+ does consume substantially more power than its predecessor.”

What exactly does that mean?

Is it possible to underclock it, in situations where all the horsepower is not necessary, but there still is a requirement for eg. WiFi?

Gordon Hollingworth avatar

Yes, there are settings to underclock if required (you could just force it to powersave mode which will peg it at 600MHz). But if you clock even lower you could undervolt as well…

Frixos Theodoulou avatar

Does this sale spread across the world? Or only in the US?
Also does this sale include the VAT or not?

The dealer here says that the product is not on sale in Europe and it is sold at its normal price.

Christian Nobel avatar

At this moment RS here in Denmark claims to have approx 4.500 in stock, and Farnell around 8.000!

James Hughes avatar

Not quite sure what you mean by sale. This is the latest Pi model, and is $35 plus local taxes/P&P. And will stay at that price.

Should be available worldwide, we have made a LOT up front so supply should be good.

AndrewS avatar

I think there’s confusion between “on sale” meaning “available for purchase”, and “on sale” meaning “being sold at a reduced price”.
In this article, it’s referring to the first meaning.

Niall Saunders avatar

Thanks again R-Pi Team,

I ‘knew’ that there had to be ‘something’ in your release pipeline – and I didn’t believe that PiTowers could be shut down by ‘the wrong kind of snow’ (as Ebene recently suggested.

So, a nice surprise to wake up to this morning, and simply the best excuse I can think of for giving my Credit Card a gentle workout.

But, why oh why didn’t you go for an octal-core processor, running at 4GHz, with 16Gb RAM and true Gigabit Ethernet that didn’t compromise the USB3 bus? ;-)

leonardo lacchini avatar

gigaethernet only 300M ? mmm

Dane P avatar

Gigabit Ethernet refers to a standard for data transmission with regards to signalling, electrical characteristics, and some other low-level stuff. The port and the Ethernet hardware are Gigabit Ethernet, just like most modern computers are, however the USB bus that the NIC sits on is not actually capable of dealing with 1Gbps of data bandwidth. That’s why they made it clear that it was capped at 330Mbps.

This is similar to a lot of consumer routers that were on sale in recent years. They were in the “gigabit routing class”, but the WAN port could sometimes only sustain 300-700 Mpbs speeds. It was a hardware limitation based on what the processor and hardware in the router could actually handle, as opposed to a limitation of the network hardware itself.

Networking started to become widespread with 10 Mbps Ethernet, which was followed by 100 Mbps (Fast Ethernet), then 1 Gbps (Gigabit Ethernet). Those numbers represent maximum or ideal speeds, and can even be affected by environmental conditions like EM noise or interference on cables. But anything that’s delivering bandwidth above 100 Mbps is using the Gigabit Ethernet standard. (Unless it’s delivering more that 1Gbps, in which case it’s 10 Gigabit Ethernet or one of the even newer standards that provides for 2.5 Gbps and 5 Gbps connections.)

DDS Central avatar

A nice update. But still with only a gigabyte of RAM, Pi is not very useful for general computing, no matter how much CPU grunt you add to it.
I understand that you are trying to stick to 35$ price tag, but I would be more than happy to pay extra money for a more substantial hardware upgrade than this.
Pi is still way behind the competition in the hardware department.
Let’s hope that the next-gen Pi will be more capable.

James Hughes avatar

If your applications need more than 1GB, you probably need to write better software. There are some exceptions. Not many.

Lots of people use the Pi for general computing, so your premise seems to be wrong, and this one is even better.

As for way behind the competition, well, not sure that is true either.

Note that moving to >1GB requires a new SOC, therefor a COMPLETE redesign of the Pi. Very expensive, very time consuming, and not something that would be expected at this point in the roadmap.

Özgür avatar

You remind me of: “*640k ought to be enough for anybody*”
This is not 1981. It’s 2018 – and you’re, please, trying to talk 1GB is enough for -almost- anyone? I consider this as a joke.
I respect and agree your -technical?- reasons. However, there are tons of people who are willing to pay more *for extra*.
I wish, you’d at least offer a more-paid-plus-plus hardware for people who are waiting for a >1GB Raspberry Pi.

J Osborne avatar

I dunno, I could go with it. I have 3 Raspberry Pi’s, and not a single one of them is suffering from memory related performance problems.

I mean, yes, I can’t take a 1G RAM Raspberry Pi and make a great ZFS server out of it, but the 1G RAM is only part of the problem, the lack of high speed external I/O is also a big deal there.

You don’t get to solve all the world’s computing needs at the $35 price point. For $35 the thing is fantastic.

More over 1G of RAM is more then enough for thousands and thousands of tasks. Bumping to 2G or 4G doesn’t really open up whole new worlds of possibilities. It just slightly nudges a window open. Don’t get me wrong, I’m a lazy programmer, if you want to give me 4G of RAM I’ll be happy to take it. I just don’t see it as world shaking.

In fact for the primary mission of the Pi (providing an entry point into CS and Entering for England’s school aged kids) 1G of RAM is far more the sufficient. After all that was done in the 1980’s on RAM measured in K bytes. The world has moved on, but not by so much that that same mission can’t be accomplished with a gigabyte. I mean it was only 2012 when 256M was sufficient for this task. Six years hasn’t moved that bar very much, 1G has lots of headroom for people just learning what Python and Scratch can do. For people learning how to wire LEDs to GPIO pins and get real world experience with hardware modification.

I totally believe that _you_ would be willing to pay more for more RAM, or that I would pay more for more RAM and SATA (& I bet more RAM will come some year, but SATA is far far less likely). I don’t think any of that is needed to make the Pi a better educational platform, and _all_ of that would require design and test time, would add SKUs to manage, and increase support burdens.

(Note: I don’t speak for the foundation, I’m not employed by them, so I’m only guessing at basically everything in here using public knowledge, and some past life experience at companies that design SOCs and such)

Congratulations on the delivery of your new Pi.

Thaddeus Woskowiak avatar

Why no hardware gigabit MAC? Lots of CPU cycles going down the drain for USB -> gigabit.

Eben Upton avatar

I don’t believe there’s a significant additional CPU load associated with running Ethernet over USB. Of course an onboard MAC would give us a full gigabit of bandwidth, but it would also necessitate some more radical surgery to the SoC.

Matt avatar

Great stuff. Figures though, I just bought 20 RPi 3B for my school 2 weeks ago! Had no idea a new model was in the works.

I’ll have to pick myself one of these today.

James Hughes avatar

Sorry – we never announce stuff like this in advance I am afraid.

W. H. Heydt avatar

Moral of the story… Do Not Buy a Pi between 1 Feb. and 15 Mar. unless in the wake of a product release. I guess. Just watch Eben release some in, oh–I don’t know–July some time. (Yes I know there have been releases at other times of the year, but the early Feb. to mid-March seems to be the “sweet spot”.)

lolo avatar

Congratulations to the raspberry pi team ;)
Thanks for this welcoming update, I immediately ordered one ^^

Keep going on folks ;)

Neil avatar

Interesting to see PoE make an appearance. I’m assuming the four-pin header is just for the four PoE lines from the Ethernet jack and that the 5V output is fed to the board through a different connector? I do hope you’ll be encapsulating the transformer to stop fingers touching the 48V DC and higher switching voltages on the transformer pins.

James Hughes avatar

As always, the PoE will adhere to all appropriate standards. One of the reasons we don’t churn out model after model like some competitors is that we actually bother to go through testing procedures and make sure that products are fit for purpose.

Neil avatar

Oh I’m sure you do James, I have no doubt ;) I remember years ago designing a PoE product and getting tingles and shocks off the flyback transformer. A perspex plate and a warning sticker kept my fingers from getting zapped.

anon34534 avatar

50v and lower is regarded as safe, which is why POE ethernet cabling can be run without an electrical permit/license. Sure you might feel a little tingle if you touch it, but it is by no means deadly.

This is why POE standards set the voltage to around the 48v mark. It is the most efficient in regards to voltage drop over a long cable run way to get power from the injector/switch to the powered device without the end user involving an electrician and permits.

Neil avatar

The behaviour of the flyback circuit could put considerably more than 48V at one of the transformer terminals. Use of a snubber to limit the primary-side ringing would help with emissions.

Gordon Hollingworth avatar

Also we made sure it will all fit inside the Raspberry Pi official case so you can protect your fingers!

Neil avatar

POE comes from the telecomms world, which has standardised on -48V DC for a variety of reasons (48V = 4 x 12V battery banks, high enough to get good signal-to-noise, low enough not to shock linesmen up poles, positive ground to minimise corrosion in underground cables, etc).

Doug Bates avatar

I’m currently running a couple of Pi3B’s 24/7 for general desktop/media stuff behind our two TVs (kitchen and lounge). Both booting from MSD SSDs. Great, love them, thanks. One question: When I set them up ~12 months ago I had to burn a one-time-programmable bit in the CPU – is it now set or do I need to repeat this stage.
Thanks again.

Eben Upton avatar

No: now we’re more confident in the MSD and PXE boot modes, these bits are blown by default.

infinitytec avatar

Nice job, but why still only 1GB RAM?

Eben Upton avatar

RAM is going through one of its periodic price spikes. It wasn’t feasible to add more to the design while sticking to the $35 price point. Don’t worry though: we’re well aware of the appetite for more RAM, and will come back to this once prices moderate.

Petr Hajek avatar

Even server RAMs are 5-10 % up so… Trend is set more like this up to 2019-20 I assume.

Eben Upton avatar

I do hope not. There was some sign of moderation early this year, but as you say it’s started to increase again.

Petr Hajek avatar

Don’t forgett that more and more gadgets share the same memory market nad pressure for inovation: we don’t have only PCs, notebooks, servers, today, but tablets, smartphones, multimedia players, consoles, … I would LOVE to be wrong, but I am realist…

Chuck Lowe avatar

WOW. You give people improvements, keep it the same price and still get complaints! These are nicely added features. I would suggest if they don’t meet your needs, buy a competitors product. While not an engineer I understand the issues of adding more RAM, USB 3.0 and dedicated Ethernet. etc. Those items cost $ and the manufacturing line process would have to be changed. I currently have a Pi3B that I have setup as a wireless router. (among other projects). I can’ wait to switch my micro card in the new model, update the OS and see the results. I live in SE Pennsylvania. Lucky enough to have a store, MicroCenter, that sells the PI line of pc and other add ons. Its actually on my way to/from work so I order online and pickup in store. No shipping required. Plus they sell the Pi3B for $29.95 and currently sell the Pi0W for an incredible $3.14. They charge more for 2 or more. Don’t understand the reasoning there. I simply place another order the next day and pick it up for the same price. These are great features. Thanks for them and for the support the Pi community has in general. Plus being a programmer/analyst, DBA, etc I’m learning python coding and enjoying it.

Eben Upton avatar

You’re lucky to live near a Micro Center. We have nothing quite like that in the UK. Still remember my first trip to a store in Brooklyn, and seeing the Pi 2 on sale at $29.95…

David avatar

Awesome to see the FCC module compliance, thanks guys!

Ton van Overbeek avatar

Addition to my previous comment.
Running apt-get update/upgrade on a pre 2018-03-13 Stretch image will make the SD-card boot on the 3B+. Of course you have to update it on another Pi.
Just tested it. Works.
And the boot to desktop (stretch-full) is clearly faster than on the 3B.

Wayne Taylor avatar

This is awesome. Purchase 1 just to support you guys. I will find a use for it, always do. :-)

POE – IOT, here we come!!
Super excited about this…we should start to see many more monitoring devices now a sensibly priced POE is an option……..
Having those power pins ‘broken out’ like that into the network adaptor will also allow much more ‘fun’ to be had with inventive ways of just ‘one cable in’ type solutions, not just POE…
this is the one we’ve been waiting for!

Vincent avatar

Hi !
As always when there’s a new Pi, my dreaded question: does this one has a real GIC or are you still using the old and ugly interrupt controller from the pi2 ? (I need a GIC for a better secure interrupt management in trustzone :D)

Eben Upton avatar

Old it is, though I prefer “beautifully simple” to “ugly”.

Vincent avatar

Dully noted, thanks for the info ;)

Mike Redrobe avatar

Can the new and improved power circuitry give us a low power standby ?

Eben Upton avatar

Yes. The unpopulated PEN (power enable) header allows you to take down the PMIC. There’s probably scope to create a HAT with a microcontroller that puts the whole Pi into an ultra-low-power state. More on this in a future post.

Mike Redrobe avatar

Thanks – managed to get something working on that pre documentation – 11 mA shutdown: https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=207961

MyCtenophore avatar

Enclosures have not been mentioned. Please tell us about compatibility of the new Pi with existing / older enclosures.

Simon Long avatar

It fits the official Raspberry Pi Case for the Model 3. It will probably fit most third party cases, as the board is the same size and connectors are in the same places, but we can’t make any guarantees – for example, it doesn’t fit the PiBow case; I believe the PoE connector is positioned where a part of the case goes.

anon34534 avatar

I’ll get excited when I can get my hands on one at the MSRP of $35 in 9 months to a year.

I really wish the PI foundation would rein in their re-sellers for the 1st few months after a release and limit sales to one per customer and outright BAN the practice of bundling them in $100 “starter packs”. These “starter packs” are just full of crap the seasoned PI user does not need. If a re-seller wanted to make the starter pack contents minus the PI a separate line item that gets a discount with purchase of a PI, I would be fine with that.

One would think that after this many product launches, they would have a clue what the demand is for these products and have a reasonable number of them available on launch date that they don’t all sell out within an hour or less.

Simon Long avatar

“I really wish the PI foundation would rein in their re-sellers for the 1st few months after a release and limit sales to one per customer…”

Oh, the irony! Have you any idea just how much stick we’ve taken over the last couple of years for applying a limit of one per customer to sales of the Zero…? ;)

Graham Toal avatar

But why are they still limited after 2 years? I understood it at first when demand outstripped supply, but 2 years is more than enough to have ramped up supply if you wanted to. At this point it seems like zero sales are being deliberately suppressed in order to sell the more profitable models. If that’s the case why did you even create the zero in the first place? I would buy dozens of zeros at retail if they were available.

James Hughes avatar

We have multiple 100k’s in the supply chain – there should be plenty. Our back office also check to make sure that resellers are not trying to make a quick buck. The Pi main models are sold in a different way to the Zero range, you might be getting the two confused.

Remember that is $35 + local taxes and P&P. Usually comes to about £45ish in the UK

anon3458 avatar

Yeah I do understand that it is not $35 inclusive of taxes shipping. I’ve generally paid between the $40-$45 mark for previous PIs in the past.

It is just quite annoying when all of the stand alone PIs are gone and all that re-sellers have left in stock are PIs that are part of some $100 starter pack.

I really wish the practice of bundling PIs in the starter packs would stop. Just sell the PIs stand alone, if the re-sellers what to sell a separate starter pack sans the PI for $100 and knock $25 or something off the price of the starter pack if ordered in the same order as a PI i would be fine with that.

James Hughes avatar

Er, what? There were over 200k Pi3B+ in the supply chain, most being sold individually. I doubt many have made it in to bundles yet. There seem to be plenty individual Pi3b+ available, so would be interesting to know whereabouts in the world you are that you seem unable to get one. Note, that the supply chain in USA was only filled yesterday due to FCC requirements, so will take a day or two to hit the shops.

The only Pi I have ever bought was part of a bundle….and everyone who sells bundles also sells individually. Are you sure you are not confusing Pi3B+ with the Pi0, which does tend to be sold in bundles.

W. H. Heydt avatar

I ordered a Pi3B+ on Tuesday afternoon for $35 plus tax (about $3) and shipping–$6 (USPS) and got it Thursday. Where are you ordering from that won’t do that?

Paul Lacatus avatar

What about a 64bit Raspbian OS ? I read that now is supported ARM v8 instruction set

Gordon Hollingworth avatar

If it’s 64bit then it’s Debian not Raspbian…

TonyH avatar

Congratulations to all involved in bringing this out!!!

Looking forward to getting one into my hands.

Tom O'Brien avatar

My cat and I are anxiously awaiting our backordered RasPi3B+.
Our goal is to implement a Google Assistant function: Hey Google, where’s the cat?

Seriously, I don’t wear a hat, but if I did, I would doff it right now to the vast Raspberry Pi team who put this new product together. As we say here in the Colonies, “Huzzah!”

Terje avatar

As it is a new chip (BCM2837B0) I am wondering if the issues with the I2C functionality are fixed regarding repeated start and clock stretching functionality?


James Hughes avatar

No change AFAIK.

Anton Wösner avatar

Hello, that´s are great news.
At what time come the Raspbian 64bit version for Pi 3B/3B+?

That was promised at Pi 3B release date, 2 years ago.


PS.: I wish for Pi 4, SATA, 4GB RAM, real 1GBit LAN, USB 3

Simon Long avatar

No, we’ve never promised a 64-bit version of Raspbian. We’ve said it is something that we are looking at but we’re not in the habit of making promises about things before we release them! It may happen at some point, but that is *not* a promise…

Joshua avatar

Hmmm…perhaps no explicit ‘promise’, but when Raspbian is the official distro and then the subsequent adoption of a 64-bit processor, I would argue you have indeed made an implicit ‘promise’ or at minimum, signalled certain intentions.

Why have Raspbian as the official distro, toss in a 64-bit chip, then say: ‘well, OpenSUSE was really clammering for it…but, please use 32-bit Raspbian & don’t expect 64-bit Raspbian…that was because of OpenSUSEs endless yammerimg; again though, don’t even think about using OpenSUSE or any other 64-bit communist distro..’?

anon5465 avatar

What’s the point? Until the PI has more than 4GB of RAM there is ABSOLUTELY NO need for 64bit OS. 64Bit isn’t faster because OMG 64bits.

The only reason the PI likely has a 64bit SOC is because it is all they could obtain at the price point they were looking for. Any 32bit only SOCs on the market are probably NOS sitting in a warehouse somewhere. The price is probably inflated since they are out of production and the assumption being anyone who wanted it would be using it for an extreme niche case. The use of an out production SOC in the PI would quickly deplete the remaining stock and they would then be stuck with releasing yet another revision for whatever different 32bit SOC they could find, or just say screw it and go to a 64bit SOC that is currently in production.

anon5465 avatar

This is probably also why the early revision Pi2 has a 32bit SOC, but the newer revision Pi2 has essentially the same 64bit SOC that the Pi3 has. Supply ran out of the 32bit SOCs, they are out of production so move to the current in production SOCs which are all 64bit.

Simon Long avatar

Exactly. There is very little value in adopting a 64-bit OS unless you actually need to access memory above the 32-bit threshold, and we don’t fit that much memory to the Pi! 64-bit OSes tend to be larger installs than the equivalent 32-bit versions (see Windows 32-bit vs. 64-bit for details – the 64-bit versions of Windows take up around 30% more hard drive space than the equivalent 32-bit versions), and SD card capacity (and download bandwidth) is still relatively pricey, so we try to keep the images as small as possible. We are able to access all of the Pi’s RAM with a 32-bit OS – until such time as we need 64-bit access, a 64-bit OS is really not a priority, and we are certainly making no promises (“implicit” or otherwise) as to when we might provide one.

Joshua avatar

So ASUS, Odroid, LeMaker, etc. ad nauseum, all had a heck of a time getting 32-bit processors for the endless run of SBCs on the market…? You notice how it’s generally harder to find out you’re looking at a 32-bit SBC than a 64-bit? Everyone who has a 64-bit chip, it’s front and center – if not part of the name of the SBC itself… The Raspberry Pi 3B is just as guilty as the rest – if you’re ringing the 64-bit dinner bell, by the time I get to my plate, I’m expecting some 64-bit meat on my plate lest the plate is smashed onto the wall. “‘Implicitly'” indeed; implicitly, there has been a promise of Raspbian 64-bit.

Look at it like this: why did OpenSUSE get a 64-bit OS ready for the Pi – perhaps there are situations where a single Pi has no need for 64-bit due to limited RAM, but more than one Pi has been sold, maybe people own more than one, and maybe they utilize them in a context that requires 64-bit. Since Raspbian should be the de facto OS, adapted to the hardware best, when I need a 64-bit OS, I don’t go to OpenSUSEs website first – usually the company that produced the device is the 1st stop.

I’m perfectly fine using other distros, but unless you can say 100% of the time, there will never be a need for a 64-bit OS on the RPi3B, then you’ve also said ‘if you need a 64-bit OS, don’t purchase our board.’ So this line of reasoning is not to the Pi’s benefit – if it is such a horrendous idea, can we assume there will then absolutely never be a 64-bit version of Raspbian that will operate on the RPi3? So, then either implicit or explicit never; right now, it is explicitly never ever – we just scored a deal on 64-bit chips, advertised the point everywhere, but just a deal nonetheless…..

‘Oh, don’t forget to buy our product! It works! …No Questions please, cash only…no real names…..You! Ugly person! Leave! No Pi for you.’

Simon Long avatar

“implicitly, there has been a promise of Raspbian 64-bit.”


No, there hasn’t. There has been no “promise” of any such thing anywhere other than in your own fertile imagination. We are keeping an eye on the requirement for and availability of a 64-bit OS, but as yet, there is no compelling common use case which requires it.

However, there *is* a compelling use case for not providing a 64-bit OS – it won’t run at all on Pi 1 or Pi Zero. The Raspbian image we ship works on all models of the Pi – this is by design, and is something we see as being hugely desirable. If we were to release a 64-bit image, we would have to do so alongside a 32-bit image. We then start to fragment the software platform; we have to build, test and support multiple images; we double the workload for every software release we make, and we have to field the inevitable support requests from beginners who have tried to run the 64-bit image on their Pi Zero and don’t understand why it doesn’t boot. At present, we do not see sufficient upside from a 64-bit OS to justify the pain.

So no, for the last time, we have never “promised” a 64-bit version of Raspbian, and we are not about to do so. As Gordon pointed out on here earlier, we’ve yet to be presented with a compelling case for providing one that is any stronger than “64 is bigger than 32, so it must be better…”

Joshua avatar

“[W]e have to field the inevitable support requests from beginners who have tried to run the 64-bit image on their Pi Zero and don’t understand why it doesn’t boot. At present, we do not see sufficient upside from a 64-bit OS to justify the pain.”

Wait…the RPi is a learning platform for beginners…and THEY would be a ‘pain’?!

*Double sigh (lol)

Certainly, I can decontextualize arguments as well – you’ve quite the spin, I’ll admit that. And you do have tact even when pushed – something that at least one angry individual answering questions on here does not.

Anyway, I can push implicit promise all day long; you just want ‘promise’ gone altogether – I will concede; I’m not out to spoil your day, nor knock down the Raspberry Pi 3B(+).

Truth be told, I’ve never even used Raspbian, even on my very first RPi I purchased. I went straight for Kali Linux because I heard you could put it on the Pi3B and I used Backtrack quite a bit back in the day. So I really have no ground to stand on speaking with regard to Raspbian.

But this is consumerism and I think direct challenges to those creating & selling a product benefit both the organization and the consumer – so I take the comment on my imagination as a compliment & I say Thank You!

Eric Olson avatar

Congratulations to the engineering team and everyone else at the Raspberry Pi Foundation! It is fantastic that a product in this price range reflects ideals of standardisation, compatibility and reliability that are usually seen only in high-end systems.

There are a number of people who express concern that Raspbian uses a 32-bit kernel and userland whereas other distributions for the Pi provide 64-bit options. As far as I know, not only is Raspbian 32 bit, but the userland further targets ARMv6 processors. One losses 64-bit integers when moving from 64-bit ARMv8 code to 32-bit ARMv7. One further losses NEON short vectors when moving from ARMv7 to ARMv6. From a performance point of view, either loss could be more than four fold or almost nothing depending on the application.

Having a well maintained operating system called Raspbian that runs without change on all models is important and one of the distinguishing features of the Raspberry Pi. Thank you for preserving my investment in time and money by keeping things compatible.

J Osborne avatar

“Until the PI has more than 4GB of RAM there is ABSOLUTELY NO need for 64bit OS. 64Bit isn’t faster because OMG 64bits.”

Sometimes yes, sometimes no. On some CPUs you need to be in 64bit mode in order to use all 64 data bits in the integer register file. Building 1024b or larger multiples out of 32b*32b -> 64b multiply is definitely faster then 16b*16b -> 32b. That is a big win even with a “limited” 1G address space. Likewise one population count on a 64b register is faster then 2 population counts on 32b registers plus an add.

On the x86 you also get more registers in 64bit mode, but I don’t believe that is applicable on the ARM, nor is it register starved like x86-32 anyway.

On other ARM systems the calling conventions were changed when going from 32bit to 64bit, generally for the better. If I recall ObjC’s send message got something like 7% faster. This may be relevant to the Pi, if the calling conventions chosen for the original Pi were derived from generations of calling conventions all backwards compatible with pre-Pi hardware (and this is very possible because they used existing compilers and existing Linux ports!).

That is a pretty small bump though, and it might not offset the additional memory pressure of addresses being twice as large (and integers as well if the common short=32b, int=64b, long=64b pattern is chosen). Both pressure on overall system RAM and on cache usage.

So more nuanced then “ABSOLUTELY NO”, but for most uses it is firmly in the “no big deal” area…and sometimes in the “definitely worse” zone.

Nathan avatar

Can I make a request that the power ceiling for future rPi be 2.4a instead of 2.5a? All of my current adapters and cables are tested for 5v 2.4a.
I’m sure a 2.4a power adapter will be fine 99% of situations, but a vast majority of 5v USB-A power adapters don’t go above 2.4a for USB2 connections.

anon5465 avatar

My guess is the next Pi will go with a USB-C port if the power req keeps climbing. I’m kinda surprised they didn’t do that with this one.

Gordon Hollingworth avatar

Problem then is that everyone has to go out and buy a new power supply… Plus USB C isn’t all that cheap at the moment, three or four times the cost for the connector in the 1m off quantity!

David bensoussan avatar

You mention 64 bit chip, will there be a better 64 bit support?

Gordon Hollingworth avatar

We’ve said in the past that if people can show an improvement in performance with a 64 bit OS then we’d think about it. It’s now been two years…


Amy avatar

date -d @2147483647
date -d @2147483648

The second command performs better on 64-bit Linux. On 32-bit Linux it gives an error because it’s past the end of time. Is the ability to use dates in/after 2038 not important? I assume everyone creating embedded systems with 32-bit Linux knows about this, right‽ :)

Simon Long avatar

I can personally guarantee that we will have a solution for this in place by 2038. Until then, it’s really not a major problem…

luminous avatar

Memory mapped IO operations, mongodb, several bits of apache software, postgresql, all benefit from larger address sizes. More so in the case of mongodb considering that on a pi, each node can only store 4gig total in the database.

And its not just about that, the extra processor registers, ability to use simd directly, rather then as a co-processor, and removal of the odd ball conditional instructions(aka simplified decode path) Give armv8 a good boost.

Simon Long avatar

When you say these pieces of software “benefit”, is that actually demonstrable in benchmarks? If so, what is the degree of benefit they see? By what percentage do they speed up?

This is what no-one has managed to provide – actual evidence of the benefits of 64-bit. If people can demonstrate a real improvement in performance in useful applications that are used by a significant proportion of the user base, we are happy to consider moving to 64-bit; but thus far, we’ve not seen any evidence that it is actually worthwhile.

David avatar

You do know there are ways to build your own 64 bit kernel with Jessie, right?
Instead of wanting everything for free handed to you, do a little googling and actually get into the project. I built a 64bit kernel last night in under 2 hours with instructions I found in forums, and it’s running… Yet the perplexing thing is, other than to prove I could do it, what was the point? I don’t have any apps that require 64 bit OS, and the Memory doesn’t require 64 bit addressing…
Quit acting like spoiled children and do something for yourselves…

david ben avatar

In my situation, it’s not about performance but I’m using 64 bits software (only) for consumer market, we are probably switch to a competitor because of it.

Joshua avatar

I have 2 RPi 3Bs, a Tinker Board, & a Rock64 4G… In terms of price of RAM at some insane price point, the Rock64 isn’t substantially more expensive than the RPi 3B+…(?). And as for power demand, it operates with a 5v/2.5A adapter…the same as the RPi 3B+. So is the difference of $20-25 really that huge of a difference, when the Rock64 also has USB 3.0, eMMC support, Gigabit Ethernet, a higher clock CPU speed, 4x the RAM at a higher clock speed, superior GPU performance, BT, IR Sensor, & endorsed by both Jesus & Moses…? Don’t get me wrong, my RPis are great & an update is cool; but why not also build a model that is at a price point a bit higher as well that can address some of desires other boards do? …btw, I hate the Tinker Board; other than pretty colors, please don’t take design cues from Asus…

Carlooser avatar

I am sorry to say that, but in Czech Republic is this not available for 35$ but for ~48.50$

Helen Lynn avatar

A 3B+, delivered, costs the equivalent of ~$48.50 in the UK too; the price is $35 plus local taxes and shipping, and of course those vary a lot according to where you are in the world, what kind of consumer you are, and so on.

fanoush avatar

For me it was slightly cheaper to buy 3B+ and 0W at pimoroni with shipping to CZ than it would be to buy same stuff via rpishop cz with local shipping. And as a bonus with pimoroni I can get another Pi Zero with each order :-) rpishop won’t sell me another cheap Zero (ever?), they previously cancelled my second Zero order few weeks after first one claiming I already have one and can’t get another! So I don’t buy with them anymore. Fortunately at Pimoroni Zero is one per order, not per customer, so that is where my Pi 3B+ money went today (and as already said it was even cheaper).

Davidben avatar

You mention 64 bit twice in the article. Will there be a support improvement ? For example more kernel support or a 64 bits raspbian.


Nick avatar

Great addition. Only thing I wish it had was additional usb power, also an actual power switch or easier way to recover from low-level mode. Maybe built in bootloader too (I know not everyone uses them, but it would be nice to have basic BIOS GUI-like controls and bootloader options)

AndrewS avatar

If you want to play with “bootloader options” take a look at https://www.raspberrypi.org/documentation/configuration/config-txt/README.md

W. H. Heydt avatar

Congrats on the “mid-life kicker”. The Pi3B+ looks to be a quite nice upgrade. Also…excited that there is at least a possibility of a Pi3A+, though I have to admit that the feeling is tempered by a long–by Pi standards–string of disappointing failures to make good on “promises” in this area, what with the cancellation of the Pi2A and non-appearance of the Pi3A.

So… Suggestions for additional upgrades…

First, the Pi3A+. The A+ is getting pretty long in the tooth and needs a refresh. Right now, there is comparatively little to distinguish an A+ from a Pi0 (even though there are sound technical differences). A Pi3A+ would, I think, provide a solid “middle choice” where a B series Pi isn’t needed or wanted and a ‘2835 based board just won’t cut it.

Second, another refresh of the Pi2B. Call it a Pi2B+ for want of anything better. It would reduce the number of BoM items to stock as all ‘2837 parts would be the B0 stepping. It could probably allow boosting the default clock of the Pi2B to 1GHz or 1.1GHz. Switching to the LAN9515 would give the same boost to Ethernet speed (and, I dare say, that would be done without changing from Pi2B to Pi2B+).

Third, it’d be nice to see CM3+ and CM3L+ modules available. I don’t expect those to appear any time soon, though. Indeed, I think the Pi3A+ deserves earlier release.

Now for a question… While it is definitively stated that the ‘2837B0 will have PxE booting enabled by default, I didn’t see anything about USB MSD booting being enabled as well. Is that OTP bit set, too? (Or are the features enabled internally without the need to set OTP bits? E.g. Don’t test the bits, just act as if they’re set?)

Gordon Hollingworth avatar

Ethernet and MSD booting are part of the same thing, so both are now enabled by default (it will still boot from SD card first though if you have one plugged in)


W. H. Heydt avatar

Thank you! I admit that I had assumed the “normal” boot sequencing as given in the documentation would still be in place.

My first Pi3B+ will be swapped in in place of a Pi3B connected (and booting from) a Pi3B. From this data, I am assuming that (following an update/upgrade cycle) should Just Work.

Pihome avatar

Congratulations from the PiHome, can’t wait to get my hands on to one of these, Thanks you for hard work.

Rune Andresen avatar

I would have expected the LAN bandwidth to be more like:

Anton avatar

Congratulations to the release!

Please, one question. I understand you don’t want to talk about future products but maybe you could say that you are not considering this at all: do you have any plans for a camera board with larger sensor? Say FourThirds larger?

Thank you!

W. H. Heydt avatar

That would be very expensive and Pis are all about being INexpensive.

Anton avatar

Sure but perhaps there could more than one model, like there is Zero and B.

Eben Upton avatar

We’re certainly aware of the market for a higher-end camera module.

Alan Pullen avatar

Will the POE hat have fixed headers in place for the POE pins or will it allow stackable headers? I.e. will it be possible to connect an additional transformer to the pins to allow a different voltage say 12v to be used for IR lamps?

Tuxedoar avatar

Ha, ha. A few days ago, I asked Eben how the hardware on RPi’s would evolve in the future!. I even wondered about the possibility of having a Gigabit update for the wired interface!. He kindly answered that, most probably, we would have that… and here it is!!. I didn´t suspect that an actual update on the RPi3 was this close!. Great surprise!!.

Congrats and thanks!.

Eben Upton avatar

I did enjoy replying to your comment the other day :)

Peter avatar

Please, please, make a faster Pi Zero.

Peter avatar

Oh, and please also consider a V2 cam with different angle lens options.

W. H. Heydt avatar

I’ll second this, but in my own way. I would suggest a camera board with a lens mount. That way, people could obtain their own lenses with whatever specs they want without burdening the RPT with sourcing and providing even a small subset of the rather large range of possibilities.

My own preference would be for a C-mount, but CS-mount would be more likely.

Craig Van Degrift avatar

I am making a digital microscope and bought an M12 mount from http://www.m12lenses.com/Board-Lenses-s/12.htm . The one I bought needed a bit of modification for the Pi Camera, but I now see that they also sell mounts specifically for Pi Camera V1 and V2. I will soon buy those along with more M12 lenses and M12 extenders. It is very nice to use M12 lenses in the Pi Camera!

TonyH avatar

Next to the RUN hole is now a hole labeled PEN. Before, there used to be a ground connector there. How is the PEN connection different?

Eben Upton avatar

PEN gives you the ability to disable the MaxLinear PMIC, completely powering down the board. More on this in due course.

TonyH avatar

Can the PEN and Run connections still be used for a reset button, or will we now have to tie into a different ground pin (from somewhere) to implement a reset button? (I’ve been soldering on a header for a reset button as a standard first step ever since I got my first Pi years ago.)

jdb avatar

PEN and RUN are signal inputs that are independent of each other.

Ground should be used from any of the GND pins on the GPIO connector.

AndrewS avatar

That’s a (slight) shame – it means simple solutions like http://raspi.tv/2012/making-a-reset-switch-for-your-rev-2-raspberry-pi won’t work any more.

TonyH avatar

Many HATs totally obscure the GPIO pins. Implementing a reset switch will now require using some sort of shim board to break out a ground pin, soldering onto the GPIO header and hoping that pushing down the HAT doesn’t mess up the solder joint, or buying something like Pimoroni’s onoff shim. It also means that a simple 2-pin female header can’t be used for the switch. I, for one, will miss having that ground hole there. I would have liked to have seen the PEN control added as another hole and the ground hole left alone. Oh well. I still look forward to the other improvements.

If I knew this I would’ve waited, I bought the 3B last sunday.

Nice refinement but too bad it’s still only 1GB DRAM. Only retro gaming use case will see some benefit but not for much else.

James Hughes avatar

Only retro gaming? Are you sure? We sell 5M devices a year with 1GB RAM. That seems slightly higher than the retro gaming market.

W. H. Heydt avatar

So long as the existing VC4 is in use, no Pi will have more than 1GB. And the VC4 isn’t going to change until a whole new SoC is developed.

So…I don’t expect any substantial changes beyond these tweaks before the Pi4B shows up.

I do kind of wonder of the LAN9515 is USB 3, at least on the upstream side…or if a fully USB 3 version exists or is in development…

AndrewS avatar

https://www.microchip.com/wwwproducts/ProductCompare/LAN7515/LAN9514 says the LAN7515 is USB2.0 only.
From Eben’s comments in the article, it sounds like it might have been specifically designed for the Pi 3B+ ?

Peter Ryan avatar

Not important but, there appears to be less screen-printing on the 3B+ board than previous boards. Why?

Eben Upton avatar

It looks nicer, and we found that we didn’t use the component labels ourselves.

Ken avatar

When I broke off L2 by using pliers to undo the mounting nut the legends allowed me to identify the component and replace it. Hopefully there will be a diagram available showing the components identifiers. Glad to see 3B+ has more space next to the mounting hole adjacent to the micro USB

luminous avatar

Ram is to expensive, so rather then requesting more, how about faster/lower power memory instead?, 1Gig of LPDDR4 would both be faster and a way to lower the power footprint, even more so if you could run it at a lower clock rate and only increase the peak bandwidth a little bit.

James Hughes avatar

Unfortunately, the controller on the SoC doesn’t support LPDDR4

John Beale avatar

Great news to read. Pi keeps getting better! My current application involving live video analytics can use every last bit of additional CPU performance available, and 1 GB is still OK for now. In the future, will be happy to put any amount of added memory to use with deep learning image-recognition networks. Obligatory nitpick: I notice the POE connector pinout seems to be exactly square. does that mean a flying-lead power connector can be attached 4 rotational positions (3 wrong ways and 1 right way)? Or I guess, intended only for a daughterboard which only fits one way?

Eben Upton avatar

As you say, the primary goal was to support a daughterboard, where the GPIO connector constrains the orientation.

Michael avatar

Nice to see! But I agree to the people who want more ram, we definately could need more of it…2gb or even more. Just watch out how browsers – or Mathematica for example – eat up the 1gb for breakfast…more ram for next Pi please.

Btw, does the new thermal throttle affect the old Pi 3b, too anyhow above 70 degree? If so, how to disable? Cause I already have a thermal controlled fan on my ‘old’ 3b.

Eben Upton avatar

We haven’t changed the clocking or voltage rules for any older products.

anon2454 avatar

I would say if you already have a working thermal solution on your PI it shouldn’t matter if the new thermal profiles are on your older PI. If your thermal solution is working it shouldn’t get that hot to trigger the thermal profile. If your cooling solution fails, then the thermal profiles might save your butt from having to buy a new PI

Michael avatar

My solution works fine – but ‘kicks in’ at 75 degree, not at 70 already, thats why I asked.

But solved as it seems to work as before. Greets, M.

Niall Saunders avatar

Don’t concern yourself about how Mathematica eats up RAM – not until you have fully understood that the RPi implementation of Mathematica is purely a ‘taster’ version of the full package.

I already made that mistake, trying to use Mathematica ‘on the cheap’ to perform a highly-detailed optical analysis of a pro-sumer astronomical telescope. Mathematica, on the Pi, simply is not up to that kind of challenge. It is quite buggy, tends to crash with alarming regularity, and (irrespective of how much RAM you make available to it) it has been released as a version that will not run on anything other than a single-core.

Sure, there are workarouds, I started by breaking the overal task into several thousands of much smaller tasks, and then collating all the data at the output of one stage to be used as input data for the next. But, this in itself was a tedious task, and very prone to user-error. A far better choice would have been to run Mathematica on the 12 cores and 128Gb of RAM of my 3.6GHz PC.

But, then again, I am a Scotsman, and I wasn’t prepared to pay the asking price for a piece of software that I was only ever going to use once !!!

So, before someone else jumps on this tired old ‘RAM’ soapbox, and starts to complain or wish for ‘more RAM and a 64-bit OS’ perhaps they ought to take the time to at least read ALL the comments that have already been made on these issues.

You don’t need a 64-bit OS, because you don’t have enough RAM in your RPi in the first place, and you are not going to get any more RAM at the current price bracket.

If you absolutely cannot live without more RAM (and the subsequent requirement for a 64-bit OS) then a Rasperry Pi solution is just not for you.

No doubt that Mathematica runs much smoother on a ‘high-end’ pc…but it is fine on my Pi, too. Enough to learn how it works and enough to do some cool animations for example.
Furthermore it should be the same as the “normal” version and definately using 4 cores, at least here for me. Without a problem. The only problem is the actual 11.2-version which only detects 1 core atm, its a bug (and already reported and being fixed in the next update) – but it could be solved easily by modifying the config file (just have a look at Wolfram-communiy for a how-to).
For sure it runs not as smooth and fast as a ‘normal’ pc – but we definately could do more with it with more ram. Same as for the browsers, just watch out how much the new Firefox 57/58/59 eat on a normal pc…if we ever want a normal Firefox again on our Pi, we definately need more ram in my opinion. Just for being ‘forearmed for the future’ at all / going with the time a bit. Sure, 1gb is “enough” – but more is better/offering more possibilities :) Years ago Bill Gates said “8 bit are enough”…but for what exactly?

timonske avatar

Will the PoE board be open source as a sort of reference implementation of PoE for the Pi? Similar to the CM IO Board.

Eben Upton avatar

That’s a good thought. We’ll certainly consider it.

M-H avatar

Yes please be as open as possible on the hardware, connections, and possibilities. As many of us might not be in schools daily, but are still learning by tinkering. Somehow still part of your target group?
I have the urge to build a HAT that contains both a POE power receiver and DAC and amp.
Thank you for cramming more and more features into the 35 dollar wonder.

Neil avatar

Check out the datasheets and application notes for the Linear Tech LTC4267 – plenty of useful circuits in the applications section. It would be helpful to know if the ethernet jack has the diodes built-in or not (I’m guessing not because of the four pins – a quick check with a DMM would verify that).

timonske avatar

These are exactly the kind of questions that would be easily answered with the PoE board getting open sourced :)
Also things like input protection and filtering can be good to know and of course vary between hardware. So a generic reference implementation of some PoE hardware is only partially helpful.

Maetes avatar

I so totally would love a Pi for a price of 80 to 100 Euro. Enough money to deal with a better Soc, 2 to 4 GM Ram, a 2nd HDMI and USB 3.0.
With a Pi like this you could replace about 90 % of all PCs in the World (my estimation). At least all PCs of all my older Family-Members. And the most PCs in gouvernments, most of the time big, energy-wasting machines dealing with one self-written, ugly programm.

Replace them with an 3 or 3+?
No way, not possible, to much isnt running properly.
To often “sorry man, this app isnt running, pi to slow or not enough Ram”.

No, I dont want to by a Mini-PC, because better Hardware isnt the only important thing. Its the software and the people behind it, what makes the pi different.

The 3+ unfortunately is another to tiny step, last great leap was the Pi-2.
And thats really … really long ago :)


Darth.Severus avatar

> To often “sorry man, this app isnt running, pi to slow or not enough Ram”.

For general desktop computer use it seems to be enought. I’m using Raspi3 as desktop, it runs Chromium with a lot of tabs open and also a shell with a lot of tabs open. I don’t think every computer really needs more. Working on grafical or video stuff is another ballpark, of course.

However, I’m using additional 1.2GB swapspace on a external disc (no ssd), you might wanna lock into that.

Noxmiles avatar

So, this will probably be the last with the VideoCore IV (except, there’s a B++).

When the Raspberry Pi 4 will be born it will be 2019 or 2020. So, after about 8 years the time has come, that the limitations of the VideoCore IV are finally reached.

So, what are the limitations of the VideoCore IV:
Max. 1GB RAM
Max USB 2.0 – therefore no real Gigabit Ethernet
Max 1080p and no VP9/h.265 native

Yes, it is great, that there is a FOSS driver. It’s the central unit of the Raspberry Pi and very important for the compatibility. But it’s from ~2010 and that’s reeeeaaaaaly old.

Probably that will be a break without backward compatiblity. But it has to be done. For the 64 bit. For the 2GB RAM. For HiDPI Screens. For the next 10 years.

ZhangYing avatar

I wished that pi has a USB signals with pin-head for easily connect to our HAT board!thanks!

Garry avatar

Top marks guys!

My very first Raspberry Pi which was ordered on launch day is still working as I type, running my MQTT and Node-RED, embedded in my home security system.
Right now I am typing this out on a Pi Model 3 stuck to the back of my TV with Velcro but as old habits die hard, it would have been rude not to order a model 3 B+ from Farnell today. Time to upgrade the back of the TV!

Thanks to the Pi team

Eben Upton avatar

I spend a lot of time looking behind TVs these days. Amazing how often you find a Raspberry Pi there. A favourite was walking into the CNN operations room in London and finding several TVs on the wall showing the Raspbian desktop.

Gerry Stilton avatar


It’s 2018, we can’t be living in a 512MB world. It’s painfully insufficient to do anything. Minimum 1GB, optionally to 4GB.

I was so excited and was ready to order until I can across the posting, that reads:


“It runs the same software, and still has 512MB RAM;”

$35 is great but 55 or even 65 if only for some more RAM please!!!

Gerry Stilton avatar


Not to throw cold water on anyone, because I am a proud owner of a raspberry pi I model B. But even Rock64 sports STANDARD 2GB of RAM of its board:


for $34.95 USD and for a 4GB, it costs $44.95 USD. Something is wrong here. How is their base model with 2GB cost less than a Pi 3 model B+, granted it lacks build-in wifi and Bluetooth. I can add that for $16 USD, but I can’t add more RAM:


But theirs is a 1.6GHz quad core. 512MB just ain’t enough. Unfortunately, I think this needs to go back to the drawing board for way more RAM.

Simon Long avatar

The Pi 3+, like the Pi 3 and the Pi 2 before it, has 1GB of RAM, not the 512MB you are quoting.

Gerry Stilton avatar

Even for non-profit such as Raspberry Pi, you have no excuse for building an inferior/non-competitive product compare to Rock64. DOA. Already time for model B+ ver 2.0

Come on, make it a success and I am ready to order a few for my robotic club kids.

Simon Long avatar

“Come on, make it a success…”

You do realise we’ve sold nearly 20 million Pis over the last 4 years? Do you not think that might already count as a “success” to most people?

Rok avatar

RPI is like a mac, when sd with raspbian is inserted, it will work. You will get updates (even for firmware). Community will solve you issues. Drivers will work out of the box.

With any other board you are basically buying some HARDWARE chips which “maybe” work together. I dont need hardware, i need a working platform. I am personally sick of thiw wanabe computers, which cause only problems, but they run on 74764Ghz. My last experience is with some android box, loaded with the latest and the greatest hardware. It is crashing, manufacturer does not provide any supprt, there are no updates for almost a year, there are some strange crashing errors of certain apps which i have never seen on android, etc., etc., etc. In one word bunch of problems.

Hope you get the point, that working solution need much more than just hardware.

AndrewS avatar

Yeah, I think the software support and stability is something that a lot of people overlook. I think it’s part of the reason why the RPi community has grown so large :)

James Hughes avatar

Why does a robot controller need more than 1GB of RAM? Seems rather excessive to be demanding more memory for something that clearly doesn’t need it

Asking for a friend.

Roger "Merch" Merchberger avatar

Just a thought…

Maybe his “Robot Controller” is SkyNet? :-)

I could see that needing a bit more memory than a standard Pi…

Michael avatar

The rason is that “some” guys using it as a desktop-replacement, for playing games, for browsing and all that other interesting stuff…and not as a controller only.

If you really need a simple controller just buy an older Pi 1 or a Pi Zero for example…but a new Raspberry with more ram or the possibility to expand the ram by the user itself just could extend the portfoilo in an awesome way.

Darth.Severus avatar

> Come on, make it a success and I am ready to order a few for my robotic club kids.

You might still have a great epiphany before you, or maybe even two: Thanks to scifi tvshows and movies many of us think robots need to have their main computer in their body. But wait, scifi is not reality, they write it so that it is most entertaining.
If your robots need more processing power, then make them connect to some bigger computer. This is actually very fascinating, because limits like power consumption for the computing in their bodies will not be so relevant any more. Oh, and they can have some kind of hive mind, like the Borg.

AndrewS avatar

I guess in a way that’s already how robots using Google or Alexa voice control services work ;)
(with the “extra processing power” simply being accessed over the internet)

Simon Long avatar

Errr – all Pi 2s and 3s have 1GB of RAM. The posting you quote is the launch announcement for a Pi from 2014, i.e. 4 years ago.

bensimmo avatar

How do you manage to get to the original B+ (Pi1), when all the info you need is in the blog you are posting too.

-There has been a 2B, 3B and now 3B+ in the B range since then, ALL 1GB of RAM, more would be nice but it’s not going to stop the majority of people buying it. If I wanted something more, I’d just buy a second hand laptop.

That B+ has ‘shrank’ into the ZeroW replacing the Ethernet with WiFi for a lot less.

Fozz avatar

I see nothing but fiddling with the product because they don’t have a Pi4 to be able to release… No big advantages here at all. No real increase in speeds, because it’s really the same chip with throttling bolted on. Big Fat Hairy Deal!! No increase in memory because the dated video core IV won’t allow it, hence no advantage to using the processor in 64bit mode, hence no 64bit OS. Yet they’re still trumpeting that it has a 64bit processor!! No point except that it’s marketing BS. Along with the usual BS about the US Dollar price, that nobody anywhere can actually buy it for.

We need 4Gigs RAM. Hell fire, I mean how much has Ram fallen in price over the last 5 years!…. Ditch the crappy video core IV for something with significantly less restriction. A Processor running at a genuine 1.8 to 2Ghz if you’re sticking to 32Bit. Not this pointless smoke and mirrors trick with throttling.. those would be an actual real improvement. All I can see in this release is marketing hype.

Nothing changes here does it….

James Hughes avatar

You are correct, we don’t have the Pi4 for release. That is some time away. This is simply a point release to make the current model a bit better, at no additional cost over the last version. We have a roadmap, and it’s going pretty well. We know what needs to be done over time, but a Pi4 is a long term project, you don’t get much changes out of three years from start to finish, if you are going to do it properly. ie, works well, robust, certified with a solid software base.

RAM prices, which clearly you haven’t been following, are going up.

As for marketing hype, well, you are entitled to an opinion, wrong though it may be. This is a clear improvement over the previous model in a number of ways – wireless, ethernet, but especially thermal management. And it’s the same price, so clearly you are getting more for your money.

Of course, not everyone will be affected by the improvements. And if you’re happy with a competitor product that does all the things you are requesting (is there one?), then get that until the Pi4 comes out.

Just out of interest, why do you need 4G of RAM? What use case ACTUALLY requires that amount of RAM, or are you just using very badly written software and need to compensate for that by throwing memory at it? When I was a lad, I had a 32K device where 20K went on the video memory. It taught me to be efficient when writing code. The original 640K PC was amazing, so much memory, but the lessons learnt remain – write decent code and reduce memory footprint

Niall Saunders avatar

@ James:

“32K RAM – with 20K dediated to (mono) video – teaches you how to code efficiently”

Hear, hear – I second that.

I’m glad I am retired, and I am glad that I never had to deal with ‘programmers’ directly – the vast majority don’t have a clue about efficient coding, not even the fact that good coding eliminates bugs at the outset.

I would probably have had to employ an assistant just to hand-write their names on their dismissal letters, just to keep up with how fast I would have been wanting to get rid of them!!

Coding is a skill – fortunately easy to acquire on the RPi platform(s) – and, just like driving a car, if you don’t take the time to learn it properly, you will eventually ‘crash and burn’. However, do you really need a Lamborghini in order to improve your driving skills? (Apparently ‘yes’, as most Audi drivers are only ever too happy to demonstrate!!!)

J Osborne avatar

“When I was a lad, I had a 32K device where 20K went on the video memory.”

Wow, what machine was that? My 8-bit era machines had way way less dedicated to video memory (8K out of 64K maybe?)

“And if you’re happy with a competitor product that does all the things you are requesting (is there one?), then get that until the Pi4 comes out.”

So I can take that as confirmation that the Pi4 will have everything I dream of to replace my ZFS file server? (more RAM, and SATA or something similar). ;-)

(honestly that is my only household project or server type system the Pi is currently unable to handle…and as I have that covered I’m not exactly going to hold my breath until the required specs fall into a $35 price umbrella…let alone until ya’ll decide that is the right set of things to spend the budget on! I mean I want fast external multidisk I/O, but I would expect ADC and DACs would be more useful to most Pi owners!)

cthulhu avatar

Good lord! I blinked and you guys put out the Zero W and now a 3B+, each more impressive than the last! Do you even sleep?

Skylarking avatar

Currently CEC can’t be used to power up the RPi however i did notice a mod can be used to provide such a feature. For details of the mod, see https://forum.kodi.tv/showthread.php?tid=174315&pid=2651811#pid2651811

So the question is, does the RPi-3B+ provide pins or solder pads for accessing the CEC wire alowing for simpler mod or better yet, is such a CEC power up feature included in the design (accessable via jumper or such?

Skylarking avatar

I had the AP2553W6-7 Load Switch IC fail on my RPi-3B some 13 months after purchase. I them replaced it with my old RPi-2 using the official PRI-3 2.5A power plug, however it died about a year later.

I know failures happen but is the RPi-3B+ built with a little more robustness as compared to earlier modles or is the RPi family considered a cheap short lived throw away item?

Great device by the way :)

James Hughes avatar

They all go through the same testing procedure, there should be no reduction in robustness over the various models. We certainly don’t consider it throwaway, although we do consider it cheap to buy!

Leo avatar

Good news.
Does GPU have any improvement for supporting DirectX?
Microsoft said the GPU of Raspberry Pi 3 doesn’t have enough capacity for supporting Directx.

Carlos avatar

I love PI but I need more memory…


Darth.Severus avatar

What for? You might need better software. Maybe also to increase your swap file.

Rok avatar

I would totaly buy a PI costing 50% more, if it would include:
-at least 2GB memory
-some better cpu (test: smooth browsing, playing 1080p youtube, watching tv stream in browser)
-USB3.0, better IO connectivitiy (test: download a large torrent with 10MB/s speed), current situation is as follows: downloading to SD cart freezes the RPI – IO chip just can not handle it, downloading to external drive will give you ~2 or 3 MB/s. Torrent speeds are more or less the same regardless of the RPI version.
-sata (NATIVE – or as close as it gets to native! not with some junky usb-to-sata bridge) would be large plus.

Christian Nobel avatar

You are barking up the wrong tree.

The Pi is perfectly capable of playing 1080p – I am using it for digital signage, and it works flawless.

And, without sounding like Bill, 1G is totally enough for the time beeing – write some decent software!

And streaming is no problem, at home I use a Pi for OSMC, and it works perfectly (the problems I face has something to do with the Danish broadcaster, not the Pi).

So if you want a PC, buy a PC.

James Hughes avatar

We don’t have a model like that I am afraid.

Erik Tamminga avatar


Does this iteration of Pi-3B+ introduce any changes to the way the Serial UARTS work? The GPIO uart vs the Bluetooth uart. Hardware vs Software.


James Hughes avatar

That’s more of a Device tree issue rather than HW (which hasn’t changed in this iteration). See https://www.raspberrypi.org/documentation/configuration/uart.md

Erik Tamminga avatar

I was hoping a new SoC and the BT update would give us a second HW Uart so we wouldn’t have to fiddle anymore with CPU clocks, overlays, etc.
Maybe next release? ;)

James Hughes avatar

Pi3B+ does NOT use a new SoC, it’s the same bcm2837. I think the BT part of the wireless chip is the same as well.

Christian Nobel avatar

As I can understand the max speed for the Ethernet is approx 300Mbps.

These 300Mbps are shared for the USB bus, so is it possible (if not network load else) to obtain at similar speed at a USB port as USB2 more or less has the same effective speed?

Next, is it possible to let the bootloader point to the USB port instead of the SD card, thereby only using a USB2 disk?

This could make a perfect mini server.

W. H. Heydt avatar

My tests of USB mass storage devices give speeds around 35mB/s, which is a pretty good approximation of 300Mn/s, so, yes, you can see the same speed. (Don’t confuse bits per second with bytes per second.)

KyRol avatar

I still awaiting RPi3 with 2GB of RAM at least. I may pay more, but still need it. Because of RAM amount I had to pick competitive SBC and I’m not happy about it until now. Please, please release 2GB revision. Also there is worth to consider another variations of units – 4GB or even 8GB of RAM. By releasing RPi with such huge amount of memory, many complex and resource hungry projects will become possible. Also operation on RAM is better than on the storage because numerous reasons. If software improvements will go by this way then many applications will become even more reliable. Please, please – think about that, do not refuse my words.

James Hughes avatar

Google would have found the answer to this, or even just reading the comments here, but to explain it one last time…..

The SoC on the Pi3 (and previous models) is limited to 1GB of RAM by the HW itself. To modify the silicon to support more than 1GB is a VERY expensive and time consuming task. It’s also something that would need to be done by Broadcom, the chip supplier, not the RPF. It’s time, in my opinion, that is better spent on the next major model release, the Pi4.

Peter avatar

I know these aren’t cutting edge questions but ..

1. Any improvement to the analog audio out?
2. Are the media Codecs still a thing? I thought something opened up on the mpeg side of things recently?


James Hughes avatar

1. Not that I am aware of.
2. Yes, patents are not yet free worldwide so we will retain the current system.

jdb avatar

Per. 1: the sigma-delta noise shaping scheme is now enabled by default in this release of Raspbian. Analogue audio now approaches 16-bit (CD-quality).

More information here: https://www.raspberrypi.org/forums/viewtopic.php?t=195178

Peter avatar

Nice !!!!

lolo avatar

Is this modification applied also on previous models, by upgrading Raspbian ?
It can be useful to drive power mosfets direcly from a Pi 0/0W GPIO’s to make a very cheap FDA with a good audio quality !

Thanks again to the fundation ;)

Marc avatar

Congrats for this new version! Has it been any change on the analog audio output?

Herbaldew avatar

Regarding from changelog “WiFi is disabled until wireless regulatory domain is set (Pi 3 B+ only)…..”

Does this mean that when I boot the first time that wifi will be enabled automatically if I have my proper wpa_supplicant.conf in the boot folder? or….

Does this mean I will have to be hardwired or connect with monitor and kb for initial wifi setup?


Serge Schneider avatar

How did you previously configure wifi without attaching a keyboard and mouse? The same approach should continue to work (just make sure your wpa_supplicant.conf has country= set).

Petr Hajek avatar

Guys, is R3 or R3+ enough for Libre Office with autocorrect and some pictures?

luminous avatar

How about pi3b+ model with the mini csi/dsi connectors like on pi zero, would be nice if pi could move towards universal cable compatibility.

Phil avatar

This is awesome! Still no built-in eMMC, though :-(

Michel avatar

Congrats on the new pi. I read a lot here about requests for ‘more memory’. As I see it the problem is not the pi3b+ design. It works as conceived: a beautiful learners board that (accidentally?) also happens to be a very decent production machine for maybe 85% of all necessary tasks. The real problem is called ‘bloatware’. Nowadays when code works, it is considered ‘finished’ when it does what the specs say. Is optimizing on size and speed still taught? Or do we leave that to ‘optimizing compilers’ instead of educated programmers?
But then, I had 128 machinewords available to write a multi-device bootloader in 1980.

Petr Hajek avatar

To everyone who thinks 1 GB is enough today and you should be better programmer – start Java IDE – half of ram just gone!

Simon Long avatar

In that case, the people who wrote the Java IDE should be better programmers! ;)

Petr Hajek avatar

Bad news is Java is still and will stay for many years most popular language… ;) https://www.tiobe.com/tiobe-index/

crumble avatar

So all modern IDE developers are bad programmers? The old times were not always the good ones. I like the features of modern IDEs, even if they need a lot of resources.

If 1GB is enough for you, ask Eben for a higher salary. When you live in in a bigger home, your vacuum cleaner will be on our side, asking for more RAM to map it ;)

James Hughes avatar

No, of course not. But some are. Otherwise how can you explain that an IDE takes up an entire 1GB of RAM? IDE facilities are great nowadays – I use Eclipse and it’s great – but the resource requirements are absurd.

1GB should be enough for the vast majority of tasks. I grew up with 32k, and you learn to write memory efficient code with that level of constraint. A skill that is sadly missing in many engineers nowadays, simply because they have never had to worry about memory requirements. It interesting to note that a number of the engineers working at Raspberry Pi grew up in an era of very limited memory, which is presumably why we are happy with 1GB – we know how to deal with those constraints.

Petr Hajek avatar

For Pi community this will be I presume much more catchy (“1 GB should be enough!”) than “640 kBs shoudld be” etc. ;)

Nicholas Mutsaerts avatar

When will the POE Hat be released?! Will there be changes to the cases to accommodate the new Raspberry Pi 3 B+ and the POE Hat?! I would like to purchase all items at the same time.

some of my cases will not work with out some Dremel work

Lee Wilkin avatar

Thank you for all your hard work on Raspberry Pi 3B+!

I’m astonished how you continue to evolve (and I really do mean evolve – user feedback (from commercial, industrial and consumer deployment) is your “environment” while efficiency and adaptation power your iterative processes).

How do you manage to improve the tech while remaining at $35? It’s an almost mystical achievement! (You’re a computing wonder of the world.)

I have Windows PCs and a couple of Macs. I love them all; but there will always be a special place in my heart for Raspberry Pi. :-)

Congratulations on your latest product. I can’t wait to get my hands on the 3B+!

P.S. Love the elevator music on your new video. :-)

Eben Upton avatar

Glad you like the elevator music. Brian (our videographer) is a stone-cold genius. I nearly fell off my chair laughing when I heard it the first time.

Paul R avatar

My Raspberry Pi 3 B+ just shipped! Can’t wait to try it out!
Suggestion for future versions: a color-coded GPIO header like on the Tinker Board. It will make setting up projects much easier.

rpiMike avatar

My Pi 3B+ turned up today. Definitely a nice speed boost and runs noticeably cooler even without heatsink/fan. Running Minecraft at just over 60 degrees.
Great work team :)

DerHerbert avatar

Will we get a Pi2-Model_B-v1.3 with an BCM2837B0?
I don’t need wlan and BT.

Eben Upton avatar

We’re considering what, if any, derivatives of the 3B+ design to put on the roadmap. Watch this space.

rclark avatar

Cool. For a $35 device, it is great (how you can fit all the neat features in for the price is just amazing). This new one looks even better. Still swimming in RAM (1G is way overkill). 1+Ghz quad processor Swimming in disk space, as I usually get 16G SD cards. SSH in to test/run apps (C/C++ or Python 3 here). I run RPIs usually headless (glad Raspbian Lite was introduced) . sftp to get/put my programs. Wireless and hardwire Ethernet, USB… Hats galore, interface to Arduinos, etc. when needed. All the amazing Linux tools at your finger tips… Far cry from when I started with Z-80s, 6502s, 680xx, 8086 back when for automation. Yet my company was able to run hydro power plants, substations and such on those ‘old’ cpus. In fact we still use 25Mhz 68332 custom boards for SCADA in some of our substations.

So, I just don’t get some of the complaints… There is so much potential here… for $35. Pocket change really. When I need extra umph for something (say cross-compile a custom kernel), or need to use a really fast graphical interface, I have desktop computers for that.

anon34879 avatar

Does this RP3+ still have the friction fit SD card slot that the RP3 had, or have you gone back to the push to eject type slot that all the previous Pi’s had?

That friction fit one on the RP3 is a PITA to get the card out of when the Pi is installed in many cases. I usually end up having to use tweezers to remove the SD card from the laser cut c4labs.net cases I like to use with all my Pi’s

Gordon Hollingworth avatar

If you buy the official Raspberry Pi case you’ll see that we thought of that!

The main problem with the Pi2 push push connector is that it was much more expensive and the lock tended to break which meant you could never get it working again without removing the tiny spring!!!

anon89673 avatar

True, but the thing I like about the c4labs and other similar cases is they have a flat top on them. I can easily stack up all my Pi’s either in use or in storage on a shelf. All 4 of my Pis 1A+, 1B+, 2B+ and 3B are all in these cases which nicely stack.

AndrewS avatar

When the friction-fit micro SD card slot was first revealed, I remember reading that lots of people accidentally ejected the card from the previous push-push slot when they didn’t mean to by picking up the Pi.

John Nicholls avatar

Congratulation to Eben and the entire RPi team, this is a great upgrade to the RPi3, I have the new RPi3 Model B+ sitting on my desk already.

Same form factor, 3 x Ethernet Speed, 3 x WiFi speed, 1.4GHz processor clock, Network bootable no SD card required when Network booting, Power over Ethernet interface, US$35 price, it does not get any better than this!!!

I think if you open source the PoE Hat design that this would leave a lot of options for all sorts of IoT capability to be designed into custom PoE Hats

As a company that designed our own custom hardware for many years, I have to say, Fantastic work RPi team!

Eben Upton avatar

Thank you. As you may gather from the video, this one has been harder to get to the finish line than any previous product. 5GHz wireless in particular is just *hard*.

No more “xenon death flash”?

James Hughes avatar

ZDF was fixed years ago….

Timo A. avatar

I didn’t know that. I can remember a discussion i had with someone who basically said the RasPi is rubbish. And one major flaw he mentioned was the XDF (or ZDF? typo??). And that was last summer.

What version of the RasPi was the first that wasn’t affected by any kind of stronger flashlight?

Liz Upton avatar

Only the very first batch of Raspberry Pi 2s were affected back in 2015 – Pis which actually demonstrate this behaviour are, funnily enough, a bit of a collectors’ item now. We replaced the affected package with one with an opaque covering immediately…and honestly, if you’ve been convinced by your buddy that a sensitivity to paparazzi is a “major flaw”, I don’t think we’re ever going to be able to bring you around! See https://www.raspberrypi.org/blog/xenon-death-flash-a-free-physics-lesson/ for more. Your friend definitely didn’t have one last summer unless he’d been one of the first people to buy a Raspberry Pi 2 and is still using that. And is regularly firing flash bulbs at it from a distance of less than ten centimetres.

(My ten cents: for some reason the Wikipedia page about Raspberry Pi, which we don’t edit because of NPOV, but which we occasionally look at and sigh at a bit, used to make a HUGE MASSIVE GREAT BIG DEAL out of the Xenon Death Flash; at one point it was about a quarter of the article. It’s really, really not a big deal and never was – it’d only affect you if you were taking close-up flash photographs of your Pi – but that weighting on Wikipedia made some people attach enormous significance to it, for some reason.)

He didn’t convince me at all and he is in no way a buddy of mine. It was a forum discussion where he numbered the “many design flaws” of the RasPi and why it is anything but robust.

Mostly he embarrassed himself because most “flaws” where in fact user mistakes that could lead to “frying” the RasPi.

At one point he claimed that not only flash lights but also sunlight or lasers could cause the RasPi to reboot. And he said that there where several components on the RasPi that could cause these light induced reboots (OpenDIE HDMI? Didn’t really understand what he was talking about. Maybe he just wanted to impress me).

I own several RasPis and never was affected by any of the problems he mentioned. Mostly because i mostly double-check what i’m doing before booting up my Pi. I even short-circuited a Zeros GPIOs once. It just didn’t boot up, wasn’t fried and still works without an issue.

James Hughes avatar

Sounds like someone making stuff up to sound impressive. Or not, in this case. Good anecdote!

Paul R avatar

I’m one of the “lucky” ones to have a Raspberry Pi 2 that suffers from the Xenon Death Flash. I discovered it when I was taking pictures of my project to upload.

“Improved PXE network and USB mass-storage booting”
Will this make it’s way to the Pi2_v1.2 and the Pi3 too?

James Hughes avatar

Not in current plans.

DerHerbert avatar

Why don’t they benefit from this enhancements? Physical limitations (as always)?

Gordon Hollingworth avatar

Because the updates done to fix this were done in the ROM on the silicon. Basically I’ve been finding bugs in the 2837A0 bootrom and fixing some of them in the B0 bootrom. The 2836 and 2835 silicon have not been through this revision and it would cost us an extra tapeout to fix…

DerHerbert avatar

TNX for clarification.
So, when do we get a Pi2 with the new 2837B0?

Ononimo avatar

I bought a 3B in January

James Hughes avatar

500k people have bought Pi3 since January!

brendan avatar

Will there be a future update that allows connection to enterprise wifi? just wondering as I would like to use my pi in university but the wifi requires account and password and its greyed out when I try to select it?

James Hughes avatar

The Pi should be able to connect to most sorts of wireless network already. If yours won’t I suggest asking about it on the forum.

Brian avatar

With all this effort to improve on the Pi 3, why did they not increase the memory to 2GB? How difficult would that have been?

Simon Long avatar

As has been pointed out repeatedly in these comments, the SoC used on the Pi 3 can access a maximum of 1GB of memory. In order to access more memory, a completely new SoC would have been needed. So the answer to your question “how difficult would that have been” is “very”.

Petr Hajek avatar

There is one funny thing though – DDR3 and DDR4 is much cheaper than DDR2. So will it not pay off in some millions of sales instead still ordering DDR2 for all today models?

I DO look forward to Pi3B+++++++ with SO-DIMM slots! ;)

Simon Long avatar

It’s not a question of money; it’s a question of the development time required to source a new SoC and to redesign the Pi (and its software) to accept it. Neither of these are trivial…

Brian avatar

If the POE Hat works with true 48v POE, then this would be a big deal as you could just plug in the pi to any available port with POE. Many organizations use Cisco POE switches just for this purpose.

Nick Pettefar avatar

I really really hope that you will soon incorporate a LI battery socket or other connection and the required hardware and software to run from the LI battery and re-charge it when 5V is re-connected and free the Pi from the wall. That’s the One Thing I prefer the (late and lamented) $9 C.H.I.P. for, the ability to run off the grid. One little socket…. come on!

I am waiting for my two new Pi 3+’s to arrive, Currently my 3’s lock up when using the Chromium browser with more than a couple of tabs and I am fed up of having to reset them.

Graham Toal avatar

I appreciate that you do incremental improvements to upgrade performance at the same price, but I can’t help but think the effort would have been better spent in ramping up production of the Pi Zero (& W) and even in upgrading the Zero to 4 core if that’s possible. Most of the projects I do with Pi’s could be done with Zeroes but getting them in units of more than 1 is impossible, and single units still have the huge shipping overhead that makes them not cost effective.

Simon Long avatar

One of the reasons the Zero is cheap is because it has an (older) single-core processor. The cost of parts is what chiefly dictates the cost of the Zero, and to keep the cost down, we can’t (at present) afford to put a quad-core processor on it. Development effort doesn’t increase the number of Zeros we can make – that’s down to limitations on how many of them the factory can produce – and it doesn’t enable us to put a quad-core on the Zero.

So, rather than sitting around twiddling our thumbs, we thought that we’d spend the time and effort on the 3B+…

I can not wait any longer and say a great big thanks to the RPT / RPF and the Community of Testers for this “update”

Now to all the people who are wanting more RAM, USB C, GigaEthernet, on-board POE etcetera, you are living in

“”cloud cuckoo land””

Go buy a Pine, Orange, Banana or whatever and enjoy zero testing, zero quality control and zero support.

The Odroid is the only SBC which is anywhere near an alternative and I am sure you will find what you need there..

Alan Givati avatar

Hello and a big congratulations to the Raspberry Pi team. Its really good to see such a solid incremental update whilst keeping the cost at $35. This is a long list of improvements that shows you really are paying attention to important details. The quality of the platform, its stabilty and community really makes this a great choice for so many projects. Thanks for your work and dedication over the years.

Andreas Müller avatar

am using P3 as musical instrument with USB keyboard. I build my images with Openembedded/Yocto and it is sooooo much fun. A project that’ll never be ‘finished’ with all aspects I love: Music/hardware/software…

When making ‘realtime’ music changing CPU frequency is something to avoid: It causes lots of so called X-Runs.

Now my question: How would P3+ behave when running kernel with governor ‘performance’ (@Pi3 1.2Ghz all the time)?

Eben Upton avatar

Quite well, I’d imagine. A 3B+ would run at a significantly lower voltage (40-50mV) than a 3B at 1.2GHz.

mihai iuliu avatar

win 10 work with Rpi3B+ ?

Jack Burton avatar

full win 10 will notwork on the Pi ,there is a win10 IOT core

Tobias K avatar

Are the mounting holes and board dimensions of the 3B+ the same as for the 3B (in other words, can the cases for the 3B also be used for the 3B+)?

Jack Burton avatar

Most cases will still fit ,there are 4 new pins for the power over internet ,that will be the way for some cases ,especially Pillow type cases ,nothing a little Drumel wont fix

Laurenti Tolledo avatar

Hi there!

Can wait to get my hands on the new RPi3B+, as of this writing still not available here in Japan though.

One question, can I just swap my RPi3 Stretch mSD image to the RPi3B+ or do I still need to re-install via NOOBS?

Simon Long avatar

You’ll need to update the firmware on your RPi 3 image before it will boot on a 3+ – sudo apt-get update / sudo apt-get upgrade should do it.

Heimo Wissing avatar

Nice work!
But what does “Improved PXE network and USB mass-storage booting” mean? Is still setup necessary with writing a write once bit? Is there a longer drive ready delay? Is that IMPROVEMENT documented anywhere?

I have just got my new pi+ it boots OK from an USB stick (No SD card). The pi seems to be running OK but the act has a constant pattern of off followed by a burst of flashes then off again – not sure if this is a concern. I also notice that only the yellow ethernet led lights up.

However, I cannot get it to boot from the network. A few seconds after power up there is the briefest glow from the act led. The Ethernet leds do not light up at all and after about 20 secs the act flashes bursts of four offs. I am able to boot from my network OK with a rpi3.

Grateful for any suggestions.

Mike avatar

If you’re using NOOBS and it was made prior to March 14, 2018, the brand-new Raspberry Pi 3 Model B+ may not boot from the SD card – even if you fully updated your system with sudo apt-get upgrade or sudo apt-get dist-upgrade.

For details on this issue, and how I resolved it, please visit my forum posting:


Mort avatar

It has already almost everything I was dreaming about. One last part is missing. The USB 3.0! :)

I would be more than happy to use the Raspberry as a NAS at the reasonable speeds.

Great work, team!

DonM avatar

I apologize if this gets posted twice – I can’t see my last message on the thread, but maybe it hasn’t been approved yet?

I was just wondering if there was an approximate ETA for the PoE Hat? Days, Weeks, Months… and is the blog the best way to find out about its release?

Thanks – really looking forward to getting the 3B+ in my hands and testing my project with PoE.

DonM avatar

AHHH – I just found Eden’s response from March 14th

“We have all the components to build our first 20k in hand, so we’re literally just waiting for a manufacturing slot. Late April if we’re lucky, early to mid May more likely.”

Percy Kawas avatar

Anyone has measured power consumed by Pi-3+ ?? My quick measurements show an increase of about 25-30%. Can anyone validate or refute this?

Helen Lynn avatar

I bet Alex Eames has written about this… ah yes, he has indeed :-)

Simon Long avatar

From what I have heard, we see about a 5% increase in power consumption on a Pi 3B+ compared to a Pi 3B – that is with wifi and Bluetooth turned off on both and no Ethernet connection. The new networking hardware on 3B+ is likely to use more power than the equivalents on the 3B, which is the (largely unavoidable) price paid for the improved performance.

Silvio avatar

Cypress CYW43455 does not use the USB bus, right?

James Hughes avatar

Its on the SDIO bus.

Blackcorvo avatar

I think these are good updates to the board,but one that’s been missing since the Raspberry Pi 2 is data over the micro USB port.
It would be much more manageable for small builds to only have one cable for power and USB data! For example a PiTop using a Lapdock.

It’s a small thing, but could make a world of difference for some people.

Chris avatar

Ordered a 3B+ and NOOBS from Farnell on the 20th, it won’t arrive until nearly the end of April! What happened to all these thousands of 3B+’s that are supposed to be available?

Dan Jones avatar

I’m currently working on a stacking HAT and I’m interested in using it in-conjunction with the new PoE HAT. How much power can the new PoE HAT deliver to the Pi? Are we talking type 2/3/4 PoE?

miguel lopez avatar

Are you going to update compute module too?
If the answer is yes, please include also wifi in the module.
It would be great.

riddick avatar

Waiting to see $35 RPi 3B+ on Amazon. I can see lots of regular RPi 3 for $35, but cheapest RPi 3B+ is $43. Aren’t 90% of RPi bought through Amazon?

JacoR avatar

Any update on the ICASA approval? We are still waiting to buy the RPI 3B+ here in South Africa.

AWS guy avatar

Amazing! Can’t wait to get one. Is amazon a good seller or should we just buy from linked retailers?
