New product launch! Introducing Raspberry Pi Model B+

Meet your new favourite piece of hardware.

In the two years since we launched the current Raspberry Pi Model B, we’ve often talked about our intention to do one more hardware revision to incorporate the numerous small improvements people have been asking for. This isn’t a “Raspberry Pi 2”, but rather the final evolution of the original Raspberry Pi. Today, I’m very pleased to be able to announce the immediate availability, at $35 – it’s still the same price, of what we’re calling the Raspberry Pi Model B+.

You're a handsome devil; what's your name?

The Model B+ uses the same BCM2835 application processor as the Model B. It runs the same software, and still has 512MB RAM; but James and the team have made the following key improvements:

  • More GPIO. The GPIO header has grown to 40 pins, while retaining the same pinout for the first 26 pins as the Model B.
  • More USB. We now have 4 USB 2.0 ports, compared to 2 on the Model B, and better hotplug and overcurrent behaviour.
  • Micro SD. The old friction-fit SD card socket has been replaced with a much nicer push-push micro SD version.
  • Lower power consumption. By replacing linear regulators with switching ones we’ve reduced power consumption by between 0.5W and 1W.
  • Better audio. The audio circuit incorporates a dedicated low-noise power supply.
  • Neater form factor. We’ve aligned the USB connectors with the board edge, moved composite video onto the 3.5mm jack, and added four squarely-placed mounting holes.

If you’re interested in precise measurements, or want to find out what the new GPIO does, check out the diagrams below.

We think you’re going to love Model B+, but to ensure continuity of supply for our industrial customers we’ll be keeping Model B in production for as long as there’s demand for it.

The B+ is available from this morning from many of the regular Raspberry Pi stockists. If you want to go direct to our two main manufacturing partners, you’ll find it at Farnell/element14/Newark here, and at RS/Allied Components here.

A few of our friends got their hands on a Model B+ on Friday, and have been playing with it over the weekend. Here’s what they had to say:

After playing around with the B+ I can safely say that it is an *immense* improvement. Great work from the Foundation!

I can’t wait to see the B+ in the community!

The Raspberry Pi Guy

Alex Eames (RasPi.TV) avatar

Congratulations. The B+ is a brilliant upgrade. :)

Ton van Overbeek avatar

Please fix the ‘Click to enlarge’ for the mechanical and GPIO diagrams. Right now they do not work.

Ben Nuttall avatar

Fixed

Liz Upton avatar

Ha – I just fixed it too! (Sorry Ton – another case of WordPress being too clever for its own good.)

ric96 avatar

Awesome!!!
Some great improvements, i really like the extra usb ports and a micro-sd slot it a thumbs up as they are more readily available!!

Patrick Binns avatar

Hack a day says one was acidently shipped to someone

Liz Upton avatar

Yeah – although not to the guy who leaked the news. What actually happened was that a store in Virginia that resells Pis (not one of our main distributors) accidentally put some on shelves on Friday. One guy bought one and took pics. The guy who bought it mentioned it on IRC (we don’t run the #raspberrypi channel – it’s a community effort), but was very cool and took the pics down when asked. Unfortunately, someone *else* who’s been trolling us for a good long time (and who managed to get himself banned from the forums etc. here more than a year ago) copied them and pretended they were his, and stuck them on his website. He was asked nicely to not ruin it for everyone else, but he spent Sunday pushing the info into as many places as possible.

Probably the most excitement the guy’s had in a long time – but it did mean we had a *hell* of a Sunday!

Martin avatar

Well done everyone at RPF, shame it was plastered over the WWW, but unfortunately whatever you do some a**e will always ruin things.

Mind you this announcement will still not stop the detractors who want more for less money !

steve avatar

It is bizarre that there are people like that. I wouldn’t have believed it, but I’ve had personal experience with other people doing the same.

They’re almost not human. They’re like evolved parasites. I’m sorry that you had the experience too. At least it shows you are successful.

David avatar

Lower power and better audio is absolutely brilliant! Are there any details of the current draw and what current can be supplied?

Simon Howroyd avatar

Bump!
I also would like to know how much power you can cram into this to stop the annoying brownouts when you hotplug WiFi dongles and the like. On the old B I ended up removing the polyfuses so I could use a 2A 5V usb charger. Can this take that kind of power natively or are “non-recommended” user mods still required?

AndrewS avatar

Already answered in comments further down this page…

AndyD avatar

Looks great. Hopefully we will see some nice cases for the Model B+ soon.

David avatar

Looks like http://www.tinkerlings.com also has the new version B Pibow cases (not B+) in stock and they are based in the U.S. I sent them a message to see when/if they will get B+ cases.

Jacob avatar

We (ModMyPi) and Cyntech, have been working on a new evolution case for the new B+ too! You can check out the new features and design process here – https://www.modmypi.com/blog/introducing-modmypis-new-case-for-the-raspberry-pi-b

Alex Bradbury avatar

Congratulations on daring to be cheesy enough to talk about “thinking outside of the box” in a case design article. That takes guts. :)

Jacob avatar

That pun is an unstoppable force of nature when writing about anything to do with case design :D

Greg Simerlink avatar

MCM has a few cases for the B+ as well: http://www.mcmelectronics.com/content/en-US/raspberry-pi

guetto avatar

The change of the SD card support is great.
I broke my first Pi in two days because of a bad fitting cage. I now have to use it with a stron paper peg.

Alex Holden avatar

Awesome, thank you very much RPi!

chris avatar

Is there enough power in the usb ports to run an external bus powered hard drive without a hub?

Liz Upton avatar

Believe so, yes. :) We’ve certainly seen that configuration work – I mean, I’m sure you could find a hard drive that draws so much power it’d need a powered hub, but most should be fine.

Derpy avatar

2.5″ hard drives that are at the 1tb mark usually need at least 5v 1a power to spin up. That is above the USB 2.0 standard of 5v 500ma…

So considering getting a power USB HDD or USB Hub to power anything in the 750gb+ range just to be safe.

mahjongg avatar

The “USB limit” doesn’t come into it in this case, but the PI does have a programmable current limiter that per default limits the output current for all USB ports together to 600mA, but with an entry in config.txt this can be increased to 1200mA, if the other USB devices together do not draw more than 200mA there should be 1A left for spin-up.

Michael Horne avatar

Congratulations on the B+. It is a huge improvement on the B in terms of layout and functionality, but not so much to make all the model B owners get grumpy about being obsolete – your Bs are still good! :-)

Oh, and good luck with Picademy today – it’s sure to be fabulous again!

Ben Nuttall avatar

Well said, Mike! And thanks.

Jan avatar

Still missing 1Gb ethernet, 1 SATA connector at least, and, what will be goal, PoE or any better power connector.

James Hughes avatar

Missing? Why would something be missing that most people don’t actually need?

You could say it’s missing a sandwich toaster…

Note this is an evolution of the Pi – your changes would need a new SoC. That would be an entirely new Pi and not as backwards compatible – which would be a mad thing to do.

ColinD avatar

Funnily enough my first thought was “I bet it doesn’t make toast” ;)

My second thought was that the extra USB with a bit more oomph in them, the micro SD, the four mounting holes and the revised port layout nicely solve all of the issues I’ve been coming across when working on a design for my cluster.

Kudos to the Foundation, and many thanks.

andrew avatar

I wouldn’t write off PoE functionality so fast.
On the other hand, I am no HW engineer but if it’s still not being considered I bet there are some drawbacks. (And you can always use a PoE splitter.)

James Hughes avatar

Proper PoE support is actually quite expensive to add to a board – that’s the real drawback.

Peter Green avatar

POE was designed to deliver substantial ammounts of power down long cables that weren’t originally intended to be power carrying with a high degree of safety for both personnel and equipment.

This however comes at a price, to implement POE properly you need:

1: beefier pulse transformers that can tolerate the DC current
2: a collection of eight diodes to deal with polarity reversal and the multiple powering options in PoE.
3: a special PoE power negotiation chip
4: an isolated DC-DC converter to go from the ~48V of the PoE line to your system supply rail.

All those extra components add up to being prohibitively expensive for the Pi.

Alex Eames (RasPi.TV) avatar

I bet it won’t be long before someone makes a mother-board for the compute module with SATA on it. :) (NO, I’m not making one, but I bet someone will)

Kushy avatar

Someone did already just google it…

Chris avatar

We plan to have two SATA interfaces on at least one of our Pi Compute motherboards!

Ian D. Scott avatar

It’s still missing a 64 bit arm processor, artificial intelligence co-processor, integrated nuclear reactor, built in 4g, warp drive…

George Dodds avatar

I saw the pics first thing yesterday, but held off posting till it was near enough plastered all over the web, ended up being a late night.

Congratulations on the B+ their are some very nice changes to the original design and it’s great to see the RasPi evolving.

Liz Upton avatar

Thanks George – it’s appreciated!

vishal avatar

please help me my project for raspberry pi in voice recognization system

Xian avatar

With switching regulators – nice.
Does that make it lower power than a model A?

StuartP avatar

Great so see the changes, and Pi moving forward.
Any more details on the
“ID_SD and ID_SC PINS:
These pins are reserved for ID EEPROM.
At boot time this I2C interface will be
interrogated to look for an EEPROM
that identifes the attached board and
allows automagic setup of the GPIOs
(and optionally, Linux drivers).
DO NOT USE these pins for anything other
than attaching an I2C ID EEPROM. Leave
unconnected if ID EEPROM not required.”

How is this automagic going to work ?

Si avatar

does the microsd slot mean no more sdcard corruption or is it literally just a different connector?

will 4 usb ports be less flaky than via a powered hub? just thinking it was bad enough with usb/ethernet being shared before, but now twice as many devices….

what’s the new minimum power requirement with the new regs (and more usb/gpio) more or less than the previous 700mA?

Dazzled avatar

I often hear complaints about this when researching the Raspberry Pi. Is this something the team is planning to address, or is it a rarer problem than I think?

James Adams avatar

The USB powrchain has a proper limiting switch and will not brown out the board if USB devices are plugged in when powered (or even if they try to take too much current or there is a fault like a power short). Default allowed USB current across 4 ports is 600mA, but can be increased to 1.2A via a config.txt parameter if a good quality 2A PSU is used. I have tried a few different USB hard disks and they all power fine directly from the Pi at the 1.2A setting.

Alex avatar

Hi James,

How can I modify the config.txt in order to support the 1.2A for the 4 USB?

Thank you in advance and congrats for the new model ;)

dom avatar
Si avatar

i think he’s referring to sdcard corruption, not usb power issues…?

David Wheeler avatar

I don’t think the Pi itself corrupts SD cards, it’s just that many SD cards are not suitable for running an operating system from.

Many small writes and reads to the same few cells of flash memory (e.g. running an OS) is a good way to corrupt a cheap SD card.

tom denton avatar

The SD card corruption is usually a result of bad power supplies. I know, because I’ve blown out a lot of SD cards using cheap usb hubs, and have some reliable power supplies that don’t corrupt the cards. I’ve switched my configuration to just boot from the SD card and then run the OS from the USB sticks, and have had no further issues. (As both usb and sd cards are flash memory, they’re equally ‘unsuited’ to being used for an OS, which confirms that running an OS on flash memory isn’t really the problem.)

Rohith M avatar

This is indeed a great news for the open hardware community. But in my country your main seller http://www.element14.com is selling Raspberry PI for Price: Rs.3,166.00(Price is before tax) which is $52 , which can never justify the price $35, it is $20 extra, which I am sure that is really more to ask for shipping and handling for such a small device.

Matt avatar

Oftentimes an increased price like that is due to import taxes imposed by your country.

Dubravko Penezic avatar

Hi, it is true that element14 have different price for diferent B version in my coutry B+ cost 7US$ more then B version vithout tax. It is hard to belive that transportation (i am in EU) cost more fore B+ version.

Aniruddha avatar

I bought one from RS components(India) at 2900/- which in USD is $47.

Grab one from them.

It just got delivered today. Though the SDCard is missing (may be not included as part of RS component package). Others are good and I’m happy :)

Harshdeep avatar

Hi.
This looks amazing!! Wanted to know if B+ is available in India?
Thanx.

-Harsh

mmmpi avatar

With the rounded corners it shouldnow fit in an altoid tin. Someone at RPi must have tried it, right?

Liz Upton avatar

It doesn’t, I’m afraid!

Peter Ryan avatar

Are the rounded-corners just there to tease Apple lawyers? ;)

99 avatar

Great job! I was to order my next batch of gadgetery and I saw this. However, my wishlist for model C is one, some or all of the following:

– Dual-core chip;
– Gigabit network;
– SATA port;

Martin avatar

Please read and learn, it is not feasible without a complete redesign, if the RPF undertook your wants everything achieved the last 2+ years would be obsoleted.

Dual Core is ARMv7, the Pi is ARMv6

a69 avatar

I am talking for a different model , not a revision of B+.

Choice is good. As there are users for model A, then a more beefed up version will also find its uses (Raspberry Pi Server?). It doesn’t need to be the same form factor, can be more expensive. Throw a cheap Raspberry Pi branded switch in the mix and we have the complete infrastructure for the schools to play on it.

MW avatar

What does a wishlist have to do with a B+ = NOTHING

Vogomatix avatar

There are systems on the market or about to be released which deliver more power and the Gigabit Ethernet, e.g. Humming Board, Banana Pi, ODroid U3, Radxa but are you also willing to pay the increased costs (about 2-5 times that of the Pi B+)??

phangmoh avatar

A+? For reduced, embedded, and low power operation? Currently stripping off the 3.3V on Model A and adding a switch mode buck through an add-on board.

j0z0r avatar

I would like to see a Model B- I guess. It comes with none of those fancy connectors to solder on so that the highest point is the power supple cap. For many of my applications, this would be ideal, and I could make the connections as needed. And surely they could save enough money scrimping on connectors to offer it for the price of a Model A or better.

I really think this would be a good seller, as many hardware modders desolder most of the ports and just connect wires to them to run to the outside of the case. Ben Heck even did the HDMI. I think the Ethernet has to have the magnetic whatevers to work properly, so that might require some work

z) avatar

Hi j0z0r!

I think many people wanted a stripped-down version, so there’s this one:

http://www.raspberrypi.org/raspberry-pi-compute-module-new-product/

Maybe it could work for you?

j0z0r avatar

This may work eventually, I was just talking about selling a regular Model B, but with none of the connectors populated. This way, I could just solder wires and source the connectors I need. The compute module doesn’t have the connections broken out, just a direct interface with the chip. I understand that I could just design a board and make it, but I don’t have the brains for concocting a 4 layer board and taking care of all the headaches that would entail. I may be able to steal someone else’s (open source of course) design and then just modify it to my own needs. But I have to wait until some boards actually come out before anyone is gonna post schematics

AndrewS avatar

Already been discussed many times on the forums, e.g. http://www.raspberrypi.org/forums/viewtopic.php?f=37&t=81464
Conclusion is it’s not gonna happen.

Dougie avatar

It has now reached a point like bicycles where the number of Raspberry Pis that I need is always the number I’ve got plus one.

MINIMAN10000 avatar

PiCount=Picount+1

The Other Peter Green avatar

PiCount+=1

:D

James Hughes avatar

In ‘C’, ++PiCount; is usually slightly more efficient.

Just sayin’

Andrew/ avatar

Just to go off topic, shouldn’t C++ really be called ++C?

James Hughes avatar

:-)

The Other Peter Green avatar

But I’m a Pythonist!

edwinj85 avatar

Wow,that looks awesome. I really want one but I’d feel bad leaving my existing model b in the lurch.

Quick question, what is meant by:

“We now have 4 USB 2.0 ports, compared to 2 on the Model B, and better hotplug and overcurrent behaviour.”

Does this mean the pi can now power things over USB like memory sticks/small portable HDDs/WiFi cards? That’s a pretty killer selling point if so.

Liz Upton avatar

Yes, that’s right.

Rogier avatar

Being able to power more powerhungry USB devices is really a great enhancement! And 2 more USB ports, I like.

Oh and one more PWM channel available. Too bad the chip itself doesn’t provide more though :-)

Gordon Henderson avatar

You will need a good PSU though! The input side will handle up to 2 amps, so if you want to feed those power hungry 3G/4G dongles then make sure your PSU is up to it!

Dimitris avatar

This is a bit of a letdown, everyone hoped for dual-core, gigabit and usb3.

Alex Eames (RasPi.TV) avatar

No they didn’t. I didn’t. Everyone – 1 != Everyone.

Anyone who reads this blog regularly will know that this was never on the cards.

Michael Horne avatar

Please read previous comments. If the Foundation released those kind of changes then all the work over the past two years would be obsolete. There are other more powerful solutions out there but it was important, at this stage, for them to maintain compatibility.

James Hughes avatar

I didn’t hope for those things either, so -2.

Marvin avatar

-3

Less power is very nice, new SD card is perfect. Moving connectors around is a very good idea, it was very ugly to plug all things to Pi. I personally don’t use GPIO, but I am sure there are plenty of folks who will be very excited now :)

Bill Stephenson avatar

Yeah, I’m far from disappointed with this.

It does most everything I would’ve hoped to do with the CM and more and I didn’t have to do anything but wait for it, so I’m absolutely thrilled with this update to the Model B.

Ordered my first one just now and it should be here this week.

bluecar1 avatar

not quite as good as first glance, you do get 7 more gpio on the 40 way block, but you lose the little connector on the rev 2 which had a few, but the power and usb more than make up for it

already ordered one from modmypi an has already been dispatched with a 8gb noobs card for £31,

just got to wait for the postie to deliver it in the next day or so

its a nice addition to the line, addresses some of the limitations we have come to know and work around, not as flexible as the CM, but the CM does have a limitation of 4gb of storage

but keeping it the same price is fantastic,

not looked yet, but do the extra gpio’s happen to be the ones used by the 2nd camera interface? as that would have been awesome?

MW avatar

+3 for happy with the B+

the only reason for wants is people are too lazy to write good software, bloatware is for Windozy users

Durval Menezes avatar

+1 to USB3, dual-core and Gigabit.
Would also add 64-bit ARM CPU and eSATA ports to the wishlist for the next Raspberry Pi.

tz1 avatar

Good, but could have been better. The arrangement and connections are a big improvement.

I was hoping for more RAM.

The bigger thing I don’t see be support for sleep or off, or similar power mode (even simply for a clean shut-down or reboot). I can send indications through the GPIO (and wonder if any other GPIO pins can act as shutdown/active indicators – I think the UART tx pin, but I want to keep the UART). But it would have been useful to just be able to connect a battery to the power in.

conrad goodwin avatar

get an odroid then! but don’t com crying to me when you have to pay $80 extra for a emmc module to keep up with all the other hardware and software to waste the cycles on!

Jorge Arias avatar

Hello,
What about audio jack? What about easy portable audio players?

What about 2 I2Cs?? i have been using I2C-0 and I2C-1 simultaneusly!!

best regards,

David avatar

This raspberry pi is nice improvement. I’d like to see all the connectors on one side of the board, but this is huge improvement to the model A or B.
It’s nice that there is 4 USB ports so now mouse, keyboard and thumb drive can be plugged in. MicroSD is improvement because I have really a lot of microSD cards and no SD cards or converters.

I have 3 Raspberry Pis running about a year now with uptime more than 100 days. They are all connected to solar power plant with RS485 converters and running 123solar. I’m very impressed how stable this is.

Good job!

vincent avatar

> I’d like to see all the connectors on one side of the board,

so much obvious

> MicroSD is improvement because I have really a lot of microSD cards and no SD cards or converters.

MicroSD is not improvement because I got a lot of SD cards and now they won’t fit. But I get RCA user can complain of redesign too.

Like some others here I’d hoped that redesign will bring us
gb ethernet, sata (and audio input)

Deltaray avatar

Gigabit ethernet uses more power than Fast ethernet. I’m glad they didn’t go that route. I guess the people wanting to run a media center off the Pi would want that, but I think there are better solutions for people who want to run a media center.

Jongoleur avatar

I was thinking about updating my 256Mb Pi model B when I saw this. You DO know when to dangle the carrot that bit closer…..

Bites!!!!

Damien Jorgensen avatar

Looks good, but please do something about the Ethernet. Get it off the USB bus.

James Hughes avatar

That’s not really possible with the current SoC.

AC avatar

Why?

Will the expansion boards work with it?

Could not you make it more similar to model B? Ie. put all sockets in similar position to use old cases with small hand-made changes?

Why the Micro SD card is not fully covered by the board?

Do we need smaller form-factor for everyday use? More GPIOs? There is a compute module for it. I think you should make the baseboard for compute module price more affordable and it would resolve all problems.

Do the new power supply circuit include charging componnets (like int the BBB)?

Why there is no so fast development on more needed things like good and cheap display.

James Hughes avatar

Please buy the original model B. That appears to be what you want.

For those people that want 4 USB ports, better power circuitry, better audio, better socket positioning and uSD card that doesn’t stick out (as much), you should buy the B+. For those in industry, buy the CM.

Maes avatar

Something that would, however, have been rather convenient (maybe for a future version?) would have been to replace one of those USB-A sockets with a ‘standard’ 4 or 5-pin header (or two USB-A connectors with a 9-pin motherboard usb header) to allow direct usb access to stacking expansion boards.

It is already currently achievable even with the classic model B but requires some rather ugly mechanical hacks due to the USB connector footprint being different from that of a 4-pin header with 0.1″ spacing.

James Hughes avatar

Problem is that the huge majority of people want a normal USB port, not a pin header. Making it a pin header just makes life more awkward (and expensive) for the majority of users.

Svenn avatar

Congrats guys! I hope that cheaper chargers now also work … (not only tablet chargers)

chris avatar

Will the Model B still be available ?

Ben Nuttall avatar

Yes, as stated in the post.

Dazzled avatar

Yes for as long as there is demand and to support industrial users.

Jim Bruges avatar

Now that the corners are rounded will it fit in an altoids tin!?

Dazzled avatar

Apparently not, according to one of those embedded videos.

Ahmed Obaidi avatar

No real time clock! No audio input!

Michael Horne avatar

You’re right. Well done.

gentboy avatar

If the power input supply enough power, will each USB port provide 500mA output as in spec?

kmf avatar

Awesome!

Mark A. Greenwood avatar

You say that you’ll keep the Model B in production while there is demand, which makes sense given the number of cases, and accessories, and to provide drop in relpacements etc. I’m guessing demand will drop of quickly though given that one of the main suppliers (element14) seems hto have remove the Model B from their site altogether. There won’t be any demand if you can’t actually buy one! It seems to still be listed on RS but for how long?

Liz Upton avatar

We stopped making Model Bs for a month so we could fill the channel with enough B+ to deal with the demand we get when we make a new product. They’re back in production again now, so you won’t have to wait for long.

PaulP avatar

I totally agree with those few, who despite of all of those fanboys, wonder why after two years, the pi foundation does not release a more up to date model.
All former projects would be obsolete?
That would be a bummer, if the community was small and there would be a large burden on very few people.
Additionally, the pi was been sold so many times and this new model, despite only having a very few minor improvements, still costs the same.
So fanboyz now go on, shred me to pieces, but be aware if you leave this blog and some other select forums, you might come across some people, who actually agree with me.

James Hughes avatar

Shred ShredShredShredShredShredShredShredShredShredShredShredShredShredShredShredShredShredShredShred

Is that enough shredding for you?

This is an evolution of the original design. You’ll have to wait longer for revolution. For example, can you name me an SoC with a VideoCore GPU in that could be used*? An awful lot of software on the Raspi has been optimised to run on the VideoCore. $100k’s worth. And what about the camera port? Do you think it is a good idea to throw all that away?

So projects that would be obsolete include – all the camera work, Maynard/Wayland, optimised web browser, anything that attaches to the GPIO’s. Which I am sure you will agree, is a LOT of stuff that would need to be done all over again.

So, instead of going on a rant as to why the spec doesn’t suit what YOU want, try thinking about why the Foundation is doing it this way, and think about the spec that the Foundation wants.

* There isn’t on.

sam avatar

The appear to be other SoCs with amrv7 and videocore4. https://en.wikipedia.org/wiki/VideoCore#Table_of_SoCs_adopting_VideoCore_SIP_blocks maybe one of those is suitable.

Otherwise is it worth sinking another $100k into videocore if it is a dead end? Were does raspberrypi aim to be in 5 years?

James Hughes avatar

There are chips out there, but they all have some sort of limitation that means they are not suitable. Be it power requirements, lack of some area of multimedia support etc.

As for the roadmap, the Foundation always keeps that very close to their chest.

sam avatar

I wonder what volumes you need to be able to influence broadcom’s SoC designs. In the early days with expectations of a few 10k units, they had to use what ever they could get. But if you want 1 million SoCs can you ask for a custom design?

James Hughes avatar

Given the development of cost of an SoC runs in to multiple $M you have to sell a lot of stuff to be able to influence/customise design. It also takes a LONG time. That’s not to say the Foundation are entirely without influence, but they are not in the same league as Samsung, or similar.

sam avatar

You wouldn’t be throwing all that work away as people would still be using the original raspberry pi’s. Right now the 1ghz arm v7 hummingboard is a much better option aside from the closed source gpu drivers.

Michael Horne avatar

One wonders why you bothered to post in the first place. I’m happy to say I’m a ‘fanboy’ (thought I hate the term) and I think the B+ is a good evolution. There are other boards out there that probably do what you want but aren’t aimed at education and a low price point.

chris avatar

I agree Paul, why not just produce a version 2.0 ? It’s like the whole apple thing with lightening connectors, non of the accessories will work/fit.

James Hughes avatar

Well, all the accessories that plug in to the GPIO should work fine – that’s backwards compatible. Cases will need to change, but if you are buying a new Pi, why not buy a new case to go with it.

u8nc avatar

its hard to follow the twists and turns of many of the conversations here because of the double negatives, and convolutions of Yoda-Style sentence construction, but the only main issue with the eventual disappearance of the B is the case and perhaps mountings.

It looks like manufacturers have been advised ahead of time, with the intent being deprecated case stock should roughly equal unsold model B’s. It will be known soon enough if model B sales are going to continue strongly to justify a case manufacturer pumping out a few more models for while, then I don’t see an Issue. I think the foundation is lucid enough to keep communicating.

The whole spirit of Pi is to overcome minor challenges by rolling-yer-own solutions, as opposed to off-the-shelf-completeness.

Blackperl avatar

Today, I have a plan to by Raspberry Pi model ‘B’, Now I fortunately make a new decision to model “B+” :).

Did you remove the pins from the P5 header on this model?
If yes, will the “old” Model B still be available?

Gordon Henderson avatar

The actual GPIO pins that were on the P5/P6 connector are not on the new B+ connector, but the functionality of those pins (essentially PCM/I2S) is available on the new pins brought out on the B+

Colin B avatar

I thought the BCM2835 only had two channels of USB (hunting for the original schematics under a pile of other schematics). Does this mean the extra two ports are paralleled onto the existing or there is now an extra hub?

James Hughes avatar

It’s all channeled down one USB port in to the SoC. In effect, the two port hub/ethernet chip has been replaced by a four port one.

MW avatar
AndrewS avatar

Correct.

gordon77 avatar

Nice upgrade.
Will accessories using the 26pin connector still work on the 40 pin connector, is the new one just an extension ?

gordon77 avatar

Sorry I’ve seen the answer now (d’oh)

PiGraham avatar

Looks good, but what has happened to the P5 GPIO 28 – 31?
No I2S?
Is there any option on B+ for high performance audio or 2nd I2C?

jdb avatar

The P5 header has been rolled into the 40-way GPIO header.

The GPIO schematic shows that GPIO0-27 are now present on P1.

jdb avatar

Oops, forgot to add that the I2S peripheral is also available on GPIO18-21.

Torsten Jaekel avatar

Yes, but in order to use the change I2S GPIO pins – a kernel patch is needed (different pinmux).

AndrewS avatar

I’ve just updated http://elinux.org/RPi_BCM2835_GPIOs with the new B+ GPIO pins :-)

niceonebro avatar

Billions of blistering barnacles in a thundering typhoon.

Torsten Jaekel avatar

I2S works on RPi B+:
http://www.tjaekel.com/T-DAC/raspi_Bplus.html

Just:
– different header pins now (and different GPIOs)
– AND: for now you need a kernel patch (I have done)

BTW: if you run B+ with the currently latest Raspbian (or Volumio) and snd modules in /etc/modules – your RPi will hang if I2S is used. The Kernel Patch is needed.

PiGraham avatar

Answered here:
http://www.raspberrypi.org/forums/viewtopic.php?p=577692#p577692

Functions still available on the 40 pin, but different lines.
All good.

OMightyBuggy avatar

Everything I like. Only thing I was looking forward too was 1GB RAM.

Peter Green avatar

AIUI while the SoC theoretically supports 1GB of ram nooone actually makes a compatible 1GB chip and given that it’s an older technology it’s unlikely they ever will.

David avatar

Now that the GPIO has 40 pins, could an off-the-shelf PATA/IDE ribbon be used to break them out??

PiGraham avatar

Of course.

AndrewS avatar

But make sure you use non-keyed connectors http://www.raspberrypi.org/forums/viewtopic.php?p=578291#p578291

nico avatar

Brilliant!

RS in South Africa now just has to add this to their online shop!

Rocsta avatar

Thanks Nico. To all those .co.za inclined: The PiFactory has ordered 200 B+ units – they will be here by the end of the week!

SamVimes avatar

Thanks nico & Rocsta – that’s good to know for us South Africans.

Niko_from_argentina avatar

Is this new model supports OpenCL?

Bob H avatar

I’m still confused as to why the foundation hasn’t moved to BCM11130, it is the successor to the BCM2835 and should be economical?

Give that the BCM11130 has ethernet MAC and USB on-board it would reduce the cost by removing the SMSC hub and only need a PHY. Perhaps Broadcom can’t release that chip into the public domain in the same way as the BCM2835 because of the security module, which would be a shame.

MW avatar

BCM11130 is based of ARMv7 and not the Pi’s ARMv6. It is not a direct replacement, so want you want is a new Pi and throw away everything which has been developed the last 2 years !

Zoltan Arvai avatar

ARMv7 is backward compatible to ARMv6. But other things can make it incompatible with the old one. And of course when an ARMv7 one will came out then a part of the community will drop the support for the old SoC.

Anyway, I like the B+. Also I think the critical voices are also useful, because they can point to problems that can be resolved later.

Juan avatar

Any supplier with international shipping to Argentina? I bought my first one from RS but now it seems it does not send here anymore.

j0z0r avatar

You guys couldn’t stop Germany. We needed you!!!

Juan avatar

Don’t you remind me of that… I will look into the referee.. I will find him, and I will kick him… Let see if after that he think that it wasn’t penalty… :'(

Is a sad day…

GekkePrutser avatar

Great, this solves a lot of issues with the original Pi. The extra USB’s are going to be super useful.

I am missing a second camera/display ports a bit though :( (since the Compute Module does have these, I was hoping there’d be a new pi with these on it as well).

And is the second UART connected on the extra GPIO’s? They’re all marked as “GPIO” on the schematic above but most have double functions so I was hoping the second UART is connected on one of these.

simon avatar

Makes embedding in a larger case much eaiser.

The right edge can goto the outside unmodified.

The bottom edge only needs extensions according to how you are getting your AV out (HDMI or oldschool). The power + SD would be internal to the box, so “no user serviceable parts”.

And the 40 pin GPIO lets you use unmodded IDE cables. The older one did but you had to cut them down the 26 pin so they tended to fall appart.

Exellent upgrade. A+++ to Eben et al. Probably was Mooncake’s idea really.

don isenstadt avatar

looks great.. but so far element 14 seems to be selling it at $50 rather than $35… am I missing something? misprint?
I see you got rid of the big capacitor!
-don

Greg Simerlink avatar

That price was an error. It is now showing $35 on the element14 site.

don isenstadt avatar

yes.. thanks.. I got an email from element 14 and then I bought it for $35 .. they had 3,400 at the time.. plenty of stock..

jon avatar

Nice as they are I would have done without all these additions if instead the new model supported wake on LAN and had a fix for SD corruption.

AndrewS avatar

Many causes of SD corruption have already been fixed in the firmware (start.elf) and Linux kernel (kernel.img).
If you haven’t already, try upgrading to the latest Raspbian.

jon avatar

I have tried that without any significant improvement.
Still regardless of my little gripes, thanks for a brilliant product, even with its little annoyances.

Kev Partner avatar

I’d just got my head around using shift registers for adding inputs and outputs so what do the Raspberry Pi Foundation do? Go and increase the number of usable pins by 50%!

Seriously though, an excellent “refresh” that addresses some of the main niggles – especially the 4 USB ports. On the other hand, the change to MicroSD, whilst welcome for new projects, means I can’t just swap the SD card out of an existing Model B – I’m not aware of any way of transferring the contents.

Michael Horne avatar

You could take an image of your current SD card and re-write the image to a micro SD? That’s assuming that the capacity of your micro is at least as large as the SD.

Stephen Scott avatar

Thanks for doing this. One of the things that keep putting me off running my Pi was the extra faff with the power supply just to run my USB hub, to overcome the lack of USB ports.

The fact I had to power down my PC, which is used heavily by my family, so as to use the monitor, keyboard and hub, kinda restricted me in how often I could play.

This revision solves at least half my problems :-)

Peter Pimley avatar

The extra USB sockets will be very useful. There are probably a lot of people running with a keyboard, mouse and something else such as a USB wifi thingie.

Daniel avatar

I can’t wait to get my handy on the new model. We are using raspberry for odb car diagnostic for long time logging.

Anode avatar

I’d pay $10 more for PoE.

And I’d LOVE to have a power connector that is just a set of pins. Micro USB blows.

GekkePrutser avatar

With the original pi you can power it through the GPIO header just fine.

I’m not sure if that’s still possible with this one but I’d assume so?

Gordon Henderson avatar

Yes, you can still power via the GPIO connector. (At least the fine boards from Pimoroni which do this work on mine)

Datta avatar

Any possibility that GPIO’s can be made 5v tolerant for easier interfacing with with most digital sensors and micro controllers?

AndrewS avatar

Only possible with an add-on board such as http://www.abelectronics.co.uk/products/3/Raspberry-Pi/37/Buffer-Pi

winkleink avatar

That’s another £30 spent on the Raspberry Pi.
Glad I waited. I’ve been meaning to get a new Raspberry Pi as both my Model A and B only have 256MB RAM.

I now feel like my Raspberry Pi tinkering will be more enjoyable with the extra GPIO and memory.
Also, perfect timing as just bought an 8GB microSD and microSD adapter for use with the Pi. Looks like I won’t need the adapter, or it means I need another SD card.

On a side note. With the curved corners and the connectors moved it just looks better.

Rocsta avatar

You know the feeling you get when you are not expecting something to get better and it does? The B+ has just done that for me.

Karthik avatar

This is very good..

Stewart Watkiss avatar

Looks a great improvement. Keeping backwards compatibility with existing add-ons (mostly), but adding more functionality.

Just ordered one – looking forward to trying out all those new GPIO ports.

dhid avatar

Hi
The B+ looks great and I’ve just ordered a couple.

However I have been using the Model B in a number of customer projects.

You state that the Model B will still be available but Farnell UK have removed the part from their website and phoning them a few moments ago I was told they are not going to stock then anymore. I don’t know if this is true or whether the person I spoke to was not properly informed.

Clicking on the Model B on the RS website says they are available from 23/12/14! Am I stuffed if I want any more Model Bs until then?

Michael Horne avatar

The Pi Hut still have some and are selling them.

Alasdair Allan avatar

See the updates at the bottom of my post on MAKE. Production of the original model B has been suspended for a month to get enough B+ boards into the production pipeline. They’ll be back…

dhid avatar

Thanks guys.

Tom Gidden avatar

Nice… Ordered.

I personally have no problem with this being a tidy-up rather than an upgrade as such.

I would’ve liked a soft reset / power button (or header) though, rather than having to hack something up with GPIO and a script. Does the SoC support something equivalent to a PC-style soft power button event?

Steve Drain avatar

The P6 hard reset seems to have gone, too. If it is on the 40W header I cannot identify it. On the other hand, I could be blind. ;-)

Nice development.

Steve Drain avatar

I have just seen that the RUN header is the same as P6, so that is good.

Dranoweb avatar

The model B has a header onboard for a reset switch, you just have to solder in a 2 pin header

vidar avatar

since the composite now is in the same plug as audio, does the cable needed to use it come with the pi B+?

mahjongg avatar

No, you can use a generic adapter, or adapter cable, made for (among many other things) the iPod. That means that most of the cheap Chinese ones should work, as they copy the Ipod wiring.
There are adapters/cables though that are wired differently, so you should be carefull. Some cables will only work if you swap the yellow and red RCA plugs, some from randow sources wont work at all if they do not use the ground wire correctly.

Normal stereo audio only (i.e. headset) plugs can be used as normally.

Tim Hawkins avatar

One of the immeadiate effects of the doubling of the gpio, is it will now be possible to run a 3d printer/cnc rig direct off the board. Each stepper motor driver needs 3 pins, and there are up to 6 steppers. Analog and digital inputs are not timming sensative so could be multiplexed via an i2c expander, but steppers need high pulse rates, and its not feasable to do that via a serial bus. Thats why arduinos etc excel that that activity. This may change things, its going to be easy to prototype a board that connects up 4-6 pololu drivers to provide x/y/z and extruder drives.

bluecar1 avatar

i have looked at this, and currently thinking it is better to drive the steppers from a I2C expander as it is a single write operation for 8 or 16bits, as opposed to a write for each gpio, less code and faster operation i think

and you still have all the gpio’s for limit sensors etc

i built the laser engraver out of dvd drives and now working to scale up and possibly add a dremel/drive with a Z axis so i can drive pcb’s / route boards for a CNC and then possibly add a hot end for a 3d printer

Tim Hawkins avatar

As far as i am aware there are no i2c based io expanders that can generate syncronised pulse trains to multiple stepper drivers at a reasonable speed, the serial bandwidth is way way too low.

To be effective the pulsetrains have to be synced so that when you are moving simultainiously in x and y, that you can control the acceleration curves so that both motors settle at the destination at the same time.

If you know of suchca device i would be very very interested.

David avatar

Funny. You don’t improve on the two parts that are the biggest ball-and-chain of the Pi; the dog-slow CPU and the measly amount of RAM.

Michael Horne avatar

Funny, you haven’t read back through the comments to find the reason why. Sorry, that was pithy wasn’t it…

Changing the CPU would mean a significant investment in terms of technology and manpower. A new version with a new CPU would also mean splitting the community and effort as the new chip would be undoubtedly ARMv7 as opposed to v6 which the Pi currently uses. If you want a more powerful CPU, there are other boards out there.

James Hughes avatar

Why is that funny? Is it the Foundation problem that the current generation of coders are just not very good at code optimisation? Or is the fact that the Pi forces people to write decent code a problem to you?

MW avatar

This record has got stuck in May 2012, try a different tune it will be sweeter, ie buy a different board !

bluecar1 avatar

thing is, the pi’s success is due to simplicity of design, cost and the size of the community that built up so quick

the pi is and always was aimed at education, but the hacking community overtook that but compliments it, as there are now many add-on boards created by this community for other to help them learn and also at a cost that schools can buy them to expand the pi

you can provide enough Pi’s for a class for less than the cost of 4 pc’s (even ignoring any additional software licenses need for a pc). at the same time parents can buy them for their kids so they can carry on at home if they get more interested in coding or electronics. therefor fulfilling the foundations primary purpose of education and creating the interest in young people to become the next generation of computer engineers / software engineers

remember that the pi was born due to a number of broadcom engineers designing the pi in their spare time, go back over the history, we owe people like gert and co and great deal as without them there would be no pi

and the cost and time to create a “new super Pi” would break with these goals at the current time, but not to say it is not something they would not consider as every piece of hardware has a finite life cycle

winkleink avatar

I know the replies to this email are correct. Just feel an explanation might be more in order rather than a longer version of RTFM. The Raspberry Pi has attracted a broad audience and so a fair number do not know the technical details.

The Broadcom BCM2835 which is heart of the Raspberry Pi is a 700MHz ARM v6 process. The v6 can only be single core and has a limited maximum clock speed. It can be pushed to 1GHz but not really beyond that.
The memory controller is built into the BCM2835 and in theory could support 1GB of RAM but the chips are not available so the maximum it can be configured with is 512MB. It’s 1 RAM chip sitting on top of the BCM2835. No option to add 2 chips. So, the Pi is running as fast as it can with the maximum amount of RAM that is available.

So, for the Raspberry Pi to have a faster process and more memory it would mean changing the chip at the heart of it. Which would make it a completely different computer. Different pin out, different built in functionality, different wiring, different operating system as it would use a different instruction set. All of this would break backward compatibility.

With the educational focus of the Raspberry Pi providing computers that are compatible so the same code and course material works on them all without modification is the priority.

A simple analogy would be buying a Ford Fiesta and then wanting it to be a V8 turbo charged beast that seats 9.
Both are cars but you couldn’t modify a Fiesta to make the second. It would need a complete re-design. Same with the Raspberry Pi.

If you are looking for something more powerful then the Beagle Bone Black or the recently announced BananaPi look interesting. Neither run Raspian, or support the Raspberry Pi libraries, or work with the camera board, and for me most importantly, neither of them have this amazing community that keeps giving new code and demonstrating new capabilities for this small slow computer with limited memory. Also, they are a bit more expensive.

Personal note: I’ve been using a Model B with 256MB RAM and everything I’ve wanted to do on it has worked, even Miecraft and XMBC.

I hope this makes sense.

Tim Hawkins avatar

The average 3d printer controller has 128-256k (not m, k) of ram, and runs on an 8bit 16mhz cpu. Compared to that a pi with 512mb, 700mhz 32bit cpu is an mcu on steroids.

Rocsta avatar

In general change is good, it challenges the status quo. If anything this should force unregulated retailers to bring their prices on the current model A & B boards down making them more affordable and popular ever. A similar action will happen on all current cases and accessories specific to the current layout because the board has changed quite dramatically. The SD card no longer being exposed is a welcome change, as is the move to mini SD. The GPIO layout of the first 26 pins is identical so theoretically any breakout board connectors will be forward compatible to the B+ but not the other way around unless you remove the RCA port on the A or B. It was largely redundant anyway and the money you would save by using an old CRT TV would have been spent later on electricity and a good optometrist

James Hughes avatar

Composite is still there – it’s now on the audio jackplug.

Keith Adley avatar

KACKPLUG? I don’t like the sound of that. Otherwise an all round excellent evolution of an already incredible device.

Keith Adley avatar

Now you made my post look silly :-)

Dranoweb avatar

RS Australia certainly aren’t selling them for the same price. They stuck a 50% markup on them.

James Hughes avatar

Well, they should be. I’ll try and get that information to the people who can sort it out (if it is indeed the case)

Dazzled avatar

Its the same thing in NZ with RS. Element14’s local resellers are way over priced as well. One of them sells the B+ for a few bucks more than the original Model B. Way to go.

shemethy avatar

Well done on the new model! I love the extra USB ports with more power, having a separate USB hub was a pain. Also great is neater cable management and better audio. I think removing the composite video port was the right move.

3xBackups avatar

The outtakes were brilliant :)
I’m guessing that I have to thank Liz for adding them – Thank you.

Double Rainbow!

Liz Upton avatar

What does it mean? :D

Ben Nuttall avatar

We just don’t know

Liz Upton avatar

*High-five*

Michael avatar

Is it necessary to use a 4-pole jack to get audio from the new av connector or will a normal stereo jack pick it up and ignore the video? I have a house full of standard audio ones but no way of getting a 4-pole one without a long delay and disproportionate shipping charges.
I was pleased to read that the quality of the audio was improved – does this include raising the output power a little? The current models require raising the volume on my stereo to a level that is dangerous if I forget to change it before changing source!

jdb avatar

Plugging a standard stereo 3.5mm jack into the socket will work for audio.

The output impedance and buffering for the audio port has been improved and the maximum output amplitude has been increased (~1.25V pk-pk).

Michael avatar

Thank you. I use hdmi if I want video but I normally work headless over VNC so that I can leave a Pi over beside my stereo as a webradio.

Tom avatar

Nice one with the extra USB. Going to have to buy another one now… :)

Lee Wilkin avatar

You Pi-guys are just *beyond* awesome! :-) I’m so impressed with all improvements on B+!

I’ve followed hardware and software evolution with great interest … *so* much hard work by *so* many people since (and before) initial hardware launch. Raspberry Pi just keeps getting better and better…. :-)

I LOVE the way you’ve focused on evolution rather than revolution (Pi 2.0) – it’s marvellously mature. :-)

I haven’t loved a computer this much since my first – an Acorn Electron. :-)

A heart-sized computer that’s had a lot of love poured into it – what a community! :-)

Craig Van Degrift avatar

You expressed all my thoughts perfectly. Well done, RPF.

Lee Wilkin avatar

P.S. the bloopers made me laugh – nice addition! :-)

Congrats to the RPi team! This is a super update, and everything I’d hoped for. I’m looking forward to seeing the new schematics and power specifications.

dave avatar

We have designed a water resistant case made in Die-Cast Zinc to house both Model A and Model B raspberry Pi’s. Our cases can be found at, http://ed-venture.biz/
Producing these Die-Cast parts meant we have invested heavily in tooling.
The layout of this B+ is so different it means we cannot use this new board in the Zinc case!
How long will model B be available for?
Will the layout of model A also change?

Ben Nuttall avatar

As it says in the post, as long as there’s sufficient demand for it.

dave avatar

Hi Ben,
Would it be possible to send me a DXF of the model B+?
I might be able to design this board into my exising product?

sam avatar

Nice refresh. Makes sense to solve as many of the small issues as possible, while remaining on the same SoC. Improved audio is good, though the wolfson card was decent work around (would be nice if raspbian supported it). I hope the USB changes mean less interference with the ethernet, which will make the pi better as a NAS. Also wonder if it will help with USB DACs.

Looking forward for Maynard to go from interesting tech demo to useful desktop, but the git repo is pretty quiet. Could the foundation set up crowdfunding to speed up the work?

I’m still looking forward to an armv7 version. It will have to happen at some point. Is it better to spend lots of dev time over the next 3 years on armv6 specific optimisation, or to make the break early so that the raspberrypi2 can be a very usable desktop. https://en.wikipedia.org/wiki/VideoCore lists some armv7 SoCs with videocore4, so surely all the existing software would work (or require only minimal porting).

Peter Green avatar

“I hope the USB changes mean less interference with the ethernet, which will make the pi better as a NAS. Also wonder if it will help with USB DACs.”
While there are more ports and better overcurrent protection the USB setup has not fundamentally changed. It’s still a single USB connection from the SoC going to a USB hub with ethernet chip from the same series (4 port version instead of 2 port version but that won’t make much different).

Dale avatar

With a revision of the model B, does this mean a model A+ revision will also ensue? You have mentioned there have been some improvements in power consumption, with the model A, rinsing a little more power efficiency out of it would be useful. I like the idea of 4 usb ports, for the most part thats keyboard, mouse, wifi, other, maybe inclusion of wifi at some point as part of the board might be possible? (with a little jumper so you can disable wifi/power for better power consumption/security)Also what about video RCA connection? I know space is limited, but theres not even a 2 pin header to plug a little cable in if you do need it (like with many >7″ monitors)? Good to see how amazing this has become :)

James Hughes avatar

You will have to wait and see.

Redman684 avatar

I find this to be the strangest change of all: For the original Pi every step in the process was published in great detail, whihc was very fun to read and really got us all excited. But now (and with the CM) the first we hear of it, is when the product goes on sale.

They went from the most open company on the planet to the most secret company on the planet ;)

I guess there will be a model A+ because the model B+ is more different from them Model B than the Model A is. They should have called it model C, but that would make it hard to make the same changes to the model A as it would than be called the model D, which would become confusing quickly.

The model A is a model B without the ethernet+hub chip. I see no reason why they couldn’t just leave that chip from the B+ and have an A+.

Richard avatar

When you’re actually shipping kit you can’t be as open about future products as when you’re not, as a lot of people will decide to hold off buying the older product until the new one comes out – and that’s painful with offices to run, bills to pay and staff salaries etc..

Liz Upton avatar

Exactly – and it’s unfortunate, because we *like* to tell people what we’re doing (we think this stuff’s really interesting, for one thing), but with the Model B the main revenue stream (not only for salaries and the office, but also for the charitable fund we run) we can’t jeopardise it by creating a situation where people decide to stop buying it because they’re waiting for something new.

Compiler avatar

Ooopssss… i just bought a Model B two weeks ago :(… and those extra USB ports would be very useful for me right now… :(

Gert avatar

Lucky they are not THAT expensive. It seems there is no such thing as a “spare Pi”. You always can find a use for it.

Pete avatar

Any plans to update the gertboard to 40 pins as well ?

ivlius avatar

Congratulations, great job!
Are there any plans to add wake on LAN?

Thank you

guest36 avatar

Brilliant that you reduced power consumption once more.
I hope, there will be a Pi with 1GB RAM and the same power consumption in some time.

Steven Dodd avatar

Nice upgrade; I want one but I don’t need one. My models A and B are working just fine.

I really like it how you have managed to keep the price point and still including upgrades.

Having the extra USB ports and the associated power improvements is nice; don’t think they were required but certainly a nice addition for sure.

g avatar

Mechanical specs in DXF. That would be awesome. Pretty please with sugar on top.

Rachel Rayns avatar

I’ve seen the bloopers a million times now and it still made me laugh this morning.

<3 team <3 B+
:)

david avatar

Nice work on the upgrade… and although yes, a “Master” revision with super-duper cpu, loads of memory, and kitchen sink would be nice – this at least does what is needed for the majority of people :)

exilaus avatar

why no add second rpi camera too!
:(

mahjongg avatar

That would mean that the PCB needs extra layers to support the extra high speed paired and length controlled CDI connections, which is expensive, much more expensive than just the cost of a second camera connector.

On the compute module they probably did add the extra layers, as they wanted to route -all- pins away from the SoC’s BGA, but is not the case on a regular PI.

Alan Broun avatar

Ummmm,

I’m a bit confused. This is going to take some time to sink in. Raspberry Pi Model B, you’ve changed? But I thought you were lovely just the way you were.

I think that the changes are great from a technical point of view. Who doesn’t want more for the same price? But I think that this could cause a lot of confusion, especially amongst newcomers, or more casual users. There are what, 3 million or so of the old form factor Pis out there at the moment? So it’s going to take a while before before the B+s become dominant. In that time I could imagine that there could be quite a few people buying cases or 3rd party add-ons for the Pi, for themselves or someone else, and going ‘what?’ I got a Model B accesory when I needed a Model B+ accessory (or vice versa) ‘how annoying’ (or more colourful words to that effect…).

Anyway, fingers crossed that increased fragmentation doesn’t lead to too may future problems. And now, I’m off to buy my new Pi. :)

daniel avatar

Nice job. Perfect for my current project :D

Can the new GPIO pins be addressed in the same way as before but with the new (higher) numbers?

with this addition, I no longer need my Arduino in my arcade project, saves some money :D

Xaveri avatar

But… WHERE IS SATA?!

Gaz99 avatar

Great News about the Pi B+, I have just ordered one. Is there any recommendations from the foundation on type / size of micro SD card to use/works best? I have to buy some :-)
Thanks

Ben Nuttall avatar

8GB is ideal, unless you need higher capacity. Class 4 is recommended.

We sell quality 8GB SD cards with NOOBS preinstalled (SD cards containing micro SD cards) for £4 on the swag store http://swag.raspberrypi.org/products/noobs-8gb-sd-card (eek currently out of stock!)

Gaz99 avatar

Thanks! – It will be a race then, which arrives first the Pi or the filling (SD-card) :-)

gordon77 avatar

Just watched the video and like the outtakes :)

Alexander von Gluck IV avatar

Nice improvements! Too bad you’ve now obsoleted all of the Raspberry Pi cases and accessories out there. There was a big market for that stuff with a lot of vendors… I’m not sure if they’re going to refactor all of their wares for a non-upgraded model with a completely different footprint.

Ben Nuttall avatar

We’ve certainly not made anything obsolete! The pinout for the first 26 pins is the same and many boards will still fit. Not to mention the fact that there are 3 million Pis out there in the original state.

Also it opens up opportunities for retailers to make new boards!

dave avatar

I Agree totally!
Our PiCE case can no longer support these changes!

Andy Crofts avatar

Still making rev.2’s forawhile,Dave.
Ordering a B+, but my B will go into a PICE next month. Think the closing-down sale was a bit premature?

LowIQGenius avatar

I can’t seem to find a retailer in the US who is offering the B+ at $35. Element14: $50.59; Allied: Unlisted

Ben Finio avatar

Looks like Adafruit has it for $39.95:

LowIQGenius avatar

Wonderful! Thanks!

dingus avatar

Still no way to shutdown without a keyboard / network.
Was hoping for a couple of pushbuttons tied to GPIO pins, one of which I could use for that purpose.

AndrewS avatar

Easily done yourself through software. Or look at something like http://www.pi-supply.com/product/pi-supply-raspberry-pi-power-switch/

TankSlappa avatar

Very nice update.
Good to see all the ports getting aligned. Cases are always the final (and often skipped) phase of a project.

Quick question on the Audio/Video 4 pole jack, which of the wiring standards have you gone with? I know from personal experience that there seem to me more variants of these cables than the permutations would deem possible!

dom avatar

Yes, deciding on which standard took a while. See:
http://www.raspberrypi.org/forums/viewtopic.php?f=63&t=81736&p=577923#p577923

TankSlappa avatar

Hopefully your video circuit won’t object to being connected to ground when a 3 pole stereo plug is inserted to just provide stereo out ;-)

Gordon avatar

Yeah that’s fine

Ben Finio avatar

Can anyone confirm the size of the new fuse on the micro-USB input? I saw a comment on Reddit that it’s 2A now (was 1.1A on the regular Model B) but can’t find the “official” information anywhere.

James Hughes avatar

I think it is now 2A, but the entire power circuit is much better, so you can have up to 1.2A on the USB outputs (with a config change, standard 600mA).

Ben Finio avatar
solar3000 avatar

I kind of love hate it. I like that they’ve allegedly improved the USB hot plugging.
Like the microUSB clicker. But now I have a stack of SD cards.

Don’t like that they moved the composite.
Wish they put in a new CPU and GPU.

M.O.B. avatar

I feel sorry for all those that invested in SD cards, because now it is the MicroSD that apply. However, I have bought the MicroSD card with adapter in recent times, but we received a donation with 4 Raspberry Pi’s to CoderDojo Lund and they have the large secure digital cards. It is good that the MicroSD card doesn’t stand out because there was a risk with the old design that the plug was damaged during transport. It is a disadvantage that it is difficult to use composite video, but it was probably necessary to move the plug into the headphone jack to fit more GPIO ports. One hopes this plug follows an existing standard.

Declan Malone avatar

re: improved sound quality

While some cleaner audio circuitry sounds nice, I didn’t see any mention about the DAC. I take it that it’s effectively the same 11-(?) bit output as the original Pis? I’m currently using a HDMI converter box with VGA (unused) and audio outputs with my Pi-based music player. If the B+ can actually output comparable sound quality without needing an expensive HDMI breakout box it would be great because I could have music/internet radio all over the house.

jdb avatar

The DAC is now of sufficiently higher quality to warrant looking at improving the 11-bit performance.

The VPU (DSP engine) in the Videocore block is more than capable of doing the cleverness required to improve the performance of the output bitstream to match up to the improved qualities of the DAC.

Declan Malone avatar

Sorry, jdb, but I don’t know what any of that means. To rephrase my question, will the new improved audio part be of good enough quality that I can do without an expensive HDMI to analogue box?
I don’t know if you’re a Foundation member, so I’d like to get an official response, if possible. Thanks.

Alex Eames (RasPi.TV) avatar

jdb is the foundation engineer who is working on this. You’re unlikely to get a more official result than the one you already have. :)

Declan Malone avatar

I still don’t understand the answer. Can someone translate it from gobbledegook to proper English, please?

AndrewS avatar

I think jdb is saying that previously (on the Model B) the interference from the power supply caused noise on the audio output which meant that there was no point trying to improve the quality of the DAC any further.

But now that the audio circuitry has a much cleaner power supply (on the Model B+) it *is* worth looking at improving the DAC code again, because you’d now be able to tell the difference. But “warrant looking at” implies that this improved-DAC work hasn’t started yet?

To answer your original question – I’m afraid I’ve got no idea how much “better” it will sound when/if this work is done. I guess all you can do is wait and see…?

JasonB avatar

Great enhancements! Does the lower power consumption allow the B+ to run cooler? Also, does the new power circuit prevent USB backpower? I would have loved to see Audio In listed in the new features. I’ve already ordered a B+ this morning. Thank you Raspberry Pi Foundation!

mahjongg avatar

“Does the lower power consumption allow the B+ to run cooler?”Total power input is lower, so total energy converted to heat is also lower, but the SoC hasn’t changed, so the total energy used by it is still the same, so it still runs cool without the need for a fan, and the electronics around it are cooler.

does the new power circuit prevent USB backpower?Yes it does! It also prevents the “rush-in-current” problem, that made you could not plug in USB devices without crashing the PI. In other words, the PI now supports hot plugging. And there is now a reasonable current limit for HDMI devices, so bus powered HDMI to VGA adapters are now officially endorsed.

I would have loved to see Audio In listed in the new features.As the Broadcom SoC does not have analog inputs, that wasn’t addable, but you can use the I2S or SPI inputs to add a ADC or codex simply enough. Especially adding an “inter IC Sound” compatible “soundcard” should be easier than ever before now that bot I2S AND I2C are available on the same connector!

M5 avatar

I saw the announcement this morning and after reading about it for just five minutes I decided to buy one. I have the Model B rev 1 with only 256mb. I can’t wait.

Thank you RPi Team.

I only have one wish, something to plug in to the display connecter. Any hope?

jdb avatar

Real Soon Now(tm)

Davey avatar

Awesome!
Well done! The improvements with the SD card is great!
I can´t agree to the demands with the cpu though :)
I´am running xbmc with a wifi dongle ( Not the most advanced stuff) BUT it´s the best and price worthy media player!
with TP-Link TL-WN725N and a Logitech Wireless Touch Keyboard K400r I could use some extra usb! ( The 50/50 port) :D

Keep up the good work !

//Davey

Sana Safinaz avatar

Loved the changes, keep improving guys :D
-Sana

Alfonso avatar

Wow, I JUST bought the old B model for the same price. Not cool :-(

ty avatar

Well, this means I’ll have to keep around a microsd converter to be able to access directly with my laptop :(

Never really needed the extra two ports (I ssh into all my rpi’s) but can see why people would want them. Quick question – does this mean these USB ports will better support USB3? (Not BE usb3, but be more compatible – there have been reports of issues of rpi & usb3 compatibility)

As for the combined audio/video, there’s a fun little thing I discovered, using omxplayer output video & audio to hdmi, whilst using mplayer output to the audio jack I had.
This was without switching amixer cset numid=3 *
Hopefully that will continue.

About the cases – I would make it clear what fits and what doesn’t, I can very easily imagine being a new user and thinking, B is pretttyyyy close to B+, it’ll probably fit.

David Hunt avatar

Raspberry Pi team – Congrats. A wonderful addition to the Pi family.
I love the fact that it’s lower power, that’s always a plus. The CPU is fine for my needs, and so is memory.
Also , great to hear that the SD is being replaced with a MicroSD. In the cases I’ve built, the blooming’ SD card was always annoying me, and the low-profile adapters were usually too thick for my liking.
Well Done, I look forward to future projects using the B+!!!
Dave.

Liz Upton avatar

*I* look forward to your future projects, Dave – it’s going to be great seeing what you get up to with it!

You’ve gotta be kidding me. Element14 wants to charge me 69 + shipping. I’m in Mexico. Also it says that it is out of stock.

Adam K avatar

Great improvements. Pity I bought mine 2 weeks ago (model B). I wish I could return it an get this one instead…

Greg Simerlink avatar

If you are looking for a Raspberry Pi B+ in North America MCM has them in stock: http://www.mcmelectronics.com/product/83-16317

Digital Defense avatar

Extra USB ports come in handy.
Happy to see the switch to micro SD. (No more ‘bendy’ SD cards)

Let’s hope the next version is an armv7 (for those of us who like that bit more power and don’t mind the extra power usage) with gigabit Ethernet.

Horacio Bertorello avatar

This is awesome news. I’m really excited about the audio improvement, but it looks like I’ll have to wait a little while to play with this here in Argentina. Shipping takes forever.

Jerry Wasinger avatar

Oh boy!

Thanks Greg! Unfortunately MCM doesn’t ship to Mexico. I’ll be visiting the US in about 40 days, I hope they’ll have some in stock then.

tuki-tuki avatar

The ethernet port is Gigabit?

AndrewS avatar

Nope, 10/100 the same as the Model B.

Okercho avatar

The lack of gigalan port is a bottleneck in the Raspberry for the HTPC use :(

Bob Holness avatar

This is a nice refresh, but please understand that a lot of people were hoping for an improvement to CPU, RAM, or both – even if this necessitates a higher price point. Highly compatible SoCs appear to be available so it’s frustrating to see the Pi get stuck down this particular technological cul-de-sac.

The “fanboy” response will of course be “if you don’t like it, go somewhere else”. Unfortunately for the Foundation that is exactly what some people will now be doing and that is a huge shame.

MW avatar

I am not a fanBoy but have great respect for the RPF and selling approaching 4 million, so a few people sell them and leave, well so what, choice is LIFE.

The more of everything is blurted out at every opportunity, but if the people who ask for more actually realised what the cost in resources is they would keep quiet.

Also the RPF is about Education and the B & B+ fit the requirements of the UK ITC Education.

Eben has stated that they will produce a Son of Pi but not for a couple of years so people will go on being disappointed, that is the way it is, and as quoted

“This isn’t a “Raspberry Pi 2″, but rather the final evolution of the original Raspberry Pi”

Bill Stephenson avatar

Well this was sure awesome and unexpected news to find waiting for me this morning.

Absolutely love the upgrades. the 4-port usb is a great addition and the micro SD is just what was needed to refine the form factor and greatly improve the aesthetics.

This does just about everything I wanted to do with the CM before learning that was pretty much out of my reach so my feelings are running from gleeful excitement to guilty shame over my brief disappointment when I thought you all had back burnered us model B developers.

I’ll never doubt you again!!!

CaptainPedge avatar

How long before you double the amount of ram in this shafting early adopters again?

James Hughes avatar

Hmm, nice post Captain Furniture polish.

Had you bothered to look stuff up, you would know that there are no 1GB RAM chips available for the SoC. So, the answer to your questions is never. BUT, because its you, if you send me your Pi, I’ll Tippex 1GB on to the RAM chip if it makes you feel better.

I presume you are referring to the increase in RAM size from 256 to 512 (at no extra cost), fairly early on? I have a 256MB Model B, works fine. I got what I paid for. Never felt shafted at all. So I suggest not looking gift horses in the mouth, as it leads to ribbing and sarcasm.

Me avatar

Oh man, my Model B arrived on the same day the Model B+ comes available. Pretty unlucky timing for purchasing a Raspberry Pi.

Dave E avatar

Nice!

I am about to Kickstart a project using R. Pi’s. This helps with some of the issues I was having.

Great news, look forward to getting a couple of these :)

Nice job all.

Stephan avatar

interesting development. I am pleased.

Fabio Naranjo avatar

Good job!

Please add a SATA port.
It is essential

Roland avatar

Will there be a Raspberry Pi A+ ?

Srayan avatar

Would have really appreciated some more RAM and a power button, but there are no ends to expectations anyway. However this looks like a massive improvement indeed.

Bill Stephenson avatar

Sorry for the double post. I’m got an error message, hit the back button and waited, tried again and got the same message, and then realized both had gone though. (With such cool news I thought your server might be crashing again ;) )

Dan avatar

If I want to move from a model B to B+ can I just clone my existing SD card to a microSD card and expect everything to continue to work correctly?

AndrewS avatar

Yep, as long as you’re using up-to-date firmware and kernel.

baboso avatar

very disappointed. expecting a performance upgrade instead of this :-(

Kevin avatar

Whereas I’m feeling pretty good about it. :D

jbeale avatar

4x USB is nice, power efficiency also nice! Same price, even better. I’m not disappointed at all, because I wasn’t expecting anything (except maybe an improvement in USB hotplugging, which I gather has now been done.) Eben had made it clear in interviews they wouldn’t be changing the SoC for some time (years) to preserve the existing investment in SW development.

Andrew/ avatar

I’m feeling pretty good about this too. When I see people moaning about wanting a performance upgrade my thoughts are that they obviously do not want a Raspberry Pi and/or they should learn to write more efficient code.

If you want more performance then Learn Assembler!

Andy avatar

I see that the B+ supports PWM pins. Can they be used as analog pins like the Arduino has?

If not, will the Raspberry Pi platform ever support analog pins or is it a limitation of the SoC used?

Liz Upton avatar

Do you mean analogue input or analogue output?

Andy avatar

Analog input pins. I want to be able to read values from analog sensors like photoresistors.

jbeale avatar

The SoC has no analog input pins, so you’d need additional external hardware to support analog input. Many options exist for add-on boards to do that.

Stewart Watkiss avatar

PWM is used to create an approximate analog output on a digital pin. The processor supports two hardware PWM channels. In the case of the model A&B GPIO 18 can be used for PWM0. I believe that the B+ adds PWM1 on GPIO19.

These are hardware based PWM signals. The advantage of these is that they don’t add any additional load to the processor.

Alternatively any GPIO port can be used as a software based PWM and you can have as many as you want, but there is a performance hit. I believe this is how most people are using PWM today and is the only method currently supported by RPi.GPIO.

There is no analog input for the Raspberry Pi, but it is possible to use an ADC IC / add-on board which can be done using I2C to interface with the GPIO.

This is not as flexible as the Arduino, but this is a completely different board. The Raspberry Pi is complete “computer” with digital only on the processor, whereas the Arduino has better handling of different input / outputs, but does not run a full operating system as the Pi does.

madara_x64 avatar

Great work with the B+! Quick question: amongst the added GPIO pins on this board, does any of them double as a PWM pin?

tzj avatar

As mentioned further up, wolfson cards are gonna be fun to mod!

Are bull brand tins the exact same size as altoid tins i wonder… will check that tomorrow.

And finally, yay!
I knew about chip change and some ‘optimisation’ on the standard B about a week ago, so yesterdays leak was quite a shock.

mahjongg avatar

Wolfson already announced they would redesign a “+” version of their audio card for the model B+.
http://www.element14.com/community/message/120305/l/wolfson-audio-card#120305

tzj avatar

Ah thats good then.

Oh and yes, the pi now fits in a ‘bull brand’ tin. :)

claudio avatar

Hi, the old revision of Raspberry PI B remain on the market? We have a large production project based on this version and rebuild our PCB is really difficult.
Thanks

Yes, it will – that’s mentioned in the video and in the blog post you’re replying to here.

Stuart DAvies avatar

Amazing update to an amazing British product. I am ordering mine now.

Can I just ask why every presentation I have seen so far anounces the price in dollars!

Let us not forget that this is a British achivement and we should wave the flag for the Raspberry PI foundation.

ukscone avatar

because the components that make up the Raspberry Pi are sold by their suppliers in dollars & cents so it makes sense to price the Raspberry Pi in them so that the price remains stable. if it was priced in pounds its price would seem to fluctuate due to currency conversion rates

francisco avatar

muy bien, solo falto mas memoria RAM, modulo wifi integrado para desocupar los puertos usb

Stick avatar

It took a while to read through that lot!
An excellent evolution of the original at the same price,
really looking like a mature product now.

Renee avatar

What, no eMMC?

Richard Brown avatar

Nice going but I have some concerns with RFI , especially as I use the Pi for High Altitude Balloon (when I get a job)and Amature Radio use*. As an engineering tech that worked with switching supplies,I am aware of possible radio frequency interface. I hope the new design will not interfere on amature radio and GPS bands. I wonder if I am correct there still no audio input jack. This is another issue with me.

* While unemployed I playing with the pi and got it to run as a standalone APRS (beacon and Igate) unit or a networked APRS TNC for to my Windows PC. Help refresh and learn Linux skills for work I am seeking.

BagOfMostlyWater avatar

Congrats on this great new product. :)

But FYI, its much harder to search the internet for “model b+” than “model c”. If customers search for “sd card raspberry pi model b+” they’ll probably get results that are more appropriate for the model b.

Dave avatar

Great to see the B+. I’ve got a B running Robot Operating System (ROS Hydro) using a USB hub and an Arduino to handle the I/O. Works ok however it’s a bit short of computing power. Any chance of a faster processor in the B++?

SileNT avatar

Is there a second UART available in B+?
That’s one of the things which Pi was lacking the most.

AndrewS avatar

Secondary UART is only available on the same pins as the primary UART :-/
http://elinux.org/RPi_BCM2835_GPIOs

mahjongg avatar

You can probably use an I2C/SPI to UART chip like the SC16IS750 to add one or more UART (serial) ports, but off course you also need to have drivers for the SC16IS750 .

Dave avatar

Great to see the B+, a great upgrade with lots of potential. I’ve got a B running Robot Operating System (ROS Hydro) using a USB hub and an Arduino to handle the I/O. Works well however it’s a bit short of computing power to run any serious navigation or perception packages. Any chance of a faster processor in the B++?

typ_o avatar

Thank you very much for not changing the system entirely – it is extremely important that you do not so much hardware forks.

Congratulations on the release of another great product. This update to the Raspberry Pi appears to be well thought out, and very useful. Again, don’t take to heart the detractors who will try and pummel you for everything you do that doesn’t involve SATA/1GbE/1GBDDR, you have a good handle on what the Pi is to the community and are doing a great job.

Uhm, they’re £26-30 – how is that cheaper?

Mike Redrobe avatar

“$35 plus local taxes and shipping / handling”…

$35 = £20

£20 + 20% VAT = £24

Dale Brandt avatar

You released the new version… The B+.

Eventually, you will release a future version … the Raspberey Pi 2.

Instead, You could advertise it as being a new “revolutionary” hardware device and call it the Raspberry 2 Pi , since tthere are 2 Pi radians per revolution.

For anybody interested we have crated a 3d model of the new Pi. Step file available here http://www.inti-innovations.co.uk/products/inti-media/inti-media-raspberrypi.html (documentation and downloads section).

Dazzled avatar

Congratulations Rasp Pi team on what looks like a very logical re-imagining of the original model B.

Don’t be disheartened by the angst I see in some of the comments. I think there is a bit of a love hate kinda vibe going on in response to the incremental rather than monumental improvements. Take it as a complement, as it shows how much people love the Raspberry Pi. Maybe to the point we feel we have a personal investment in it.

Obviously there is allot of pent up demand for something more powerful. I’m feeling it too. Im sure this is a good sign for the future.

exartemarte avatar

A neat tidying up job on what was already a very successful product – thank you!

I will certainly buy one (as soon as there’s a case I like) for my NAS server – I’ll be able to dispense with the hub, which has been a rectal discomfort, and tidy up the wiring considerably.

I’ll probably still use Model As for battery powered robots, though – unless there’s an A+ in the offing …

kneekoo avatar

Awesome job you guys did with model B+. :) My shopping list just got bigger and I look forward for RasPi 2. ;)

TGMN avatar

Hey all, apologies if this question has already been answered elsewhere, but how good is the audio? I’ve seen talk about 11-bit, but what’s the sampling rate?

Furthermore is the Pi compatible with external DAC’s / ADC’s?

jbeale avatar

There are several external ADC and/or DAC boards for data acquisition. For high quality audio, there is the Wolfson Audio board using the I2S interface, but until now it has been designed for Port 5 on the R-Pi Model B (rev.2) and not the RPi B+ which has removed P5 in exchange for an expanded P1.

mahjongg avatar

Wolffson has announced a version for the Raspberry PI model B+ already.
Even though for many people the redesigned audio (A/V) jack output will now suffice better than the old one (but if “better” is good enough is obviously a personal choice).

Torsten Jaekel avatar

I2S works, see here:
http://www.tjaekel.com/T-DAC/raspi_Bplus.html

Just: temporary jumper wires AND kernel patch needed.

Zoltan Arvai avatar

There are some cheap hdmi -> hdmi+audio (spdif/analog) and hdmi->dsub+audio devices on ebay that can be a good alternative for that. Those devices requires no driver, because they are using hdmi audio.

Ha, just bought a Pi last week. Still, it suits my purpose just fine and I don’t consider it obsolete (not by a long shot), although I’m a bit envious the lower power consumption of the B+. Then again, my fourth Pi will be a B+. Great job.

Boris Wilson avatar

To the Raspberry pi Creators, Developers, Testers I say THANK YOU! Thanks to you my girls feel empowered to learn all they can about the power of a ones imagination mixed with technology. Who knew $35 could change someones life instantly. All the best and looking forward to the future.

Kiran Lonikar avatar

I would have a loved a revision on the lines of hardkernel’s Odroid-U3. Agreed it is priced higher ($90 including shipping). I wonder if that was the reason for not going for Quad core, 2GB RAM kind of specs.

James Hughes avatar

Er, yes. Clearly. Price point is vital. You cannot build a quad core 2GB RAM device for $35. $90 is nearly three times the cost of the current Model B.

Akash Marathe avatar

Awesome upgrade from the Raspberry Pi Foundation. Worked extensively with the Raspberry Pi Model B and was awestruck by it’s versatility. Hope the B+ upgrade shall be a success in many ways!
Keep up the good work!!!

Ion avatar

Is it possible to supply more than 5V?
I have a 12V regulator, used to power other devices. Now, model B+ has a switching power supply, can I supply 12V?

James Hughes avatar

No, max is about 5.25 IIRC.

Tommy avatar

Can I run four external drives on this? Or tree and a USB dongle for wifi?

mahjongg avatar

There is about 1.2 Ampere available for the four USB ports (with a line in config.txt) which seems not enough to directly power FOUR hard disks, but if you externally power the hard-disks it shouln’t be a problem. The B+ now also solves the back-feeding issue, so you do not have to worry about that (but power distribution from one HD to the next might be a new issue with multiple simultaneously externally powered HD’s, if they all try to put power on the USB bus, but that isn’t a PI specific problem.

Brijesh Kumar avatar

Does B+ support microphone port ?

mahjongg avatar

No the SoC has not changed, and it doesn’t support any audio input hardware. You can add an audio input by adding your own I2S (Inter IC Sound) audio codec through I2S signals now available on the 40-pole GPIO header.
Wolffson has announced they will release a B+ version of their “audio card”, which supports multiple microphones, and microphone inputs.

AndrewS avatar

Or you can add a USB sound card with a microphone input.

Geoff avatar

I guess the 3.5mm jack is 4 pole now. Is the pinout Right Audio, Left Audio, Video and Ground, counting from the tip.

MW avatar

The best place to ask general questions is in the Forum,see:

mahjongg avatar

“I guess the 3.5mm jack is 4 pole now. Is the pinout Right Audio, Left Audio, Video and Ground, counting from the tip.”

No, because the connector setup is compatible with a normal stereo jack, and those have the left, (not the Right) Channel at the tip, the right channel on the ring (and GND on the sleeve)

The order is fully compatible with adapters (or adapter cables) for the iPod, so you can use cheap Chinese adapter cables designed for the iPod (or for the Microsoft Zune, which copied the same layout)

Geoff avatar

I got 0 out of 4 correct. Maybe I should stop playing the lottery.

mahjongg avatar

You got 2 out of 4 correct, only switched the tip and the ring (left and right).

condew avatar

I really like the new, more efficient use of power. I want to use a Pi to monitor my cabin, and as a 24-hour load on my very small solar installation, this small improvement in efficiency will be a big help. I didn’t need another Pi, but better power and 4 USB ports just convinced me to buy 3 more.

Will the Secondary Memory Interface be available on the new GPIO connector?

Yes the whole of bank 0 is now accessible…

But you’ll have to wait for some further documentation on SMI first (this is in the pipeline)

Thank you. I know about the documentation and that is the most important news for me. I hope it will be announced in a blog post.

SMI pins exposed + new serial eeprom pins: I sense a memory extension coming! (ZX81 16k extension, anyone?)

mahjongg avatar

It would be amazing if the RPF can pull this “secondary memory” trick out of their high hat. Nobody would have thought any new fast memory interface interface would have been possible, the raspberry PI never ceases to amaze. :-)

That said, a secondary memory interface does NOT mean the RAM can be expanded beyond the current maximum of 512MB !
Instead, if it will ever be implemented it will become a secondary memory device with far faster access than either SD-Card, or USB memory.
http://en.wikipedia.org/wiki/Auxiliary_memory

This means it can be used as a kind of very fast virtual memory (dedicated memory swap device).

What this means in practice has to be seen, but for any hardware implementation it has to be noted that almost all GPIO pins will be used to connect the actual memory chip(s).
It will mean that some trickery will be needed when this “SIDE RAM” (to keep the tradition of using BBC computer related terms) needs to be combined with any use of the GPIO’s. I’m sure something smart can be developed.

For now we just have to wait and see how this plays out.

mahjongg avatar

Actually the new EEPROM mechanism, are intended for future “stackable expansion modules” called “HAT’s”, (comparable with Arduino shields, but made stackable) . Each stackable expansion module can announce with its EEPROM which if the various I/O subsystems of the GPIO header it will use. So the PI can combine the I/O of those various modules.

At this moment the details are still very vague, but in the near future we will probably hear more.

Will the B+ still reboot like the B does when you’re switching around hard drives?

mahjongg avatar

No, the B+ PI now has hot plug support, so you can now plug in a USB device after bootup.

ColinD avatar

*LOL* I’d always thought this was a bug… never occurred to me it was just a lack of hot swap support *head desk*.

WooHoo to the new hot plug support. That’s my new favourite thing.

Mike Redrobe avatar

lack of hotplug was a “bug” introduced with the loss of polyfuses after rev1.

Rev1 with polyfuses did have hotplug support, but had problems powering usb devices

Now we have hotplug support back with B+, and no powering problems either.

Rob Hendry avatar

Hi chaps,

B+ Arrived this morning. Quick question … will the micro sd slot support a 64gb card?

Cheers

mahjongg avatar

Only the card connector itself has changed, so it will support the same types of cards the model B does (if they mechanically fit, obviously).

Andrea avatar

As someone who bought a Pi Model B just one month ago, I am a bit disappointed. A fair warning, ideally combined with a discount plan for resellers to get rid of stocks, would have been very welcome. I guess business reasons come first. Still, even the evil corporations usually announce their new models/revisions in advance, so you know you’re buying an obsolete item :)

Anyway: I wrote my rant, I feel better and I’m still happy the Pi exists and to own one.

James Hughes avatar

How can you discount something that is already discounted as cheap as it will go? It’s making sure all stock gets sold that is one of the main reason behind keeping quiet about new product launches, sorry, but that’s just the way it is. It happens with everything.

A avatar

I have no objection to the Pi’s price – I’m actually amazed by it! My mention of a discount was a preemptive reply to the natural objection that announcing the B+ model would have hurt current stocks and discounts are the common countermeasure to that. My complaint is that resellers came before users, which is nothing new but still not pleasant at all, especially considering that – like the blog post mentions – demand for the original model will still exist for hardware consistency reasons.

Finally, it doesn’t happen with everthing. Even revisions of gaming consoles and high-end smartphones are announced a week to a month in advance – and we’re talking about some big sharks here, not charities. 0 days is new to me.

All in all, I stated my case and I am still disappointed, you rightfully stand by your decision and I thank you for your reply.

AndrewS avatar

So you’d prefer there to be a announcement, and then have to wait before you can buy it, rather than being able to buy it on the same day of the announcement? ;-)

AndrewS avatar

And I guess the “big sharks” make much more profit per unit, and thus they have more “headroom” with which they can offer discounts.

Andrea avatar

Sure, I do prefer there to be an announcement, so that I can decide whether to wait for the new, better model or get the previous one anyway (often for a discount). Inevitably someone will still make their purchase just before the announcement and will not have a chance to choose, but like I said before, going straight from complete silence to release is quite extreme and strikes me as very consumer-hostile, something I wouldn’t expect from a charity.

James Hughes avatar

I think, because they are a charity (and cannot afford to lose money), and there is no room to discount old product (prices are already as low as possible), this is exactly the right mechanism to use. Given the previous two point, if the B+ was announced 6 months ago (when the first boards were prototyped), there would be few if any sales of the B for those months, any B’s in the supply chain would likely need to be crushed as no-one would buy them, or if sold would probably be sold at a loss. A charity cannot afford that. Read up on the Osbourne effect. Announcing early killed that company.

Andrea avatar

And about “the sharks”, they do have high margins on high-end phones, but not on gaming consoles, for example. And they also have a lot more to lose so… tough call. :)

u8nc avatar

Actually, you have a notification of a future release** right now. The best time to have bought a Pi is before the release of the B+. I’ll explain why:

most people find that they need a second one anyway as a development board at on the test bench, and their second purchase out in the field actually doing stuff without extricating it from whatever mounting.

the B is virtually identical from a coding point of view, and when you are ready to commit it to use in a robot, or remote webcam or hydroponics monitor or whatever, a low power model A+ ( impending** ) is ideal.

A avatar

I’m afraid I didn’t really get your point.

bart van thielen avatar

Will it be possible to turn power to the USB ports off? I am having problems with a USB GSM modem and the only way to reset it is to turn it off and on again.
Or was this already possible on the normal model B also?

mahjongg avatar

No power to the USB ports is hard wired, but unlike the older models you now can safely remove and re-plug USB devices.

bart van thielen avatar

Somebody told me to post this question on the forum, and there I got a different answer:

Yes.

The 9514 hub’s power control is hooked up to the USB power switch. Sending a control message via USB can power it off/on.

USB 3G modem? Yeah…Had an early Model-B, had to short out the polyfuses, that thing sucks power
“Darling, are you using your USB modem?”
“Yeah, why do you ask?”
“I can’t seem to get the kettle to boil…”

Gordon avatar

Yes it is possible through the 9514 since it controls the USB power switch…

But there is currently no software to do it…

Gordon

bub avatar

I wonder if you could cut off everything to the right of the mounting holes (USB and ethernet) for a mini-Pi (or maybe the A+).

Making it into a permanent prototype area for the Model A+ would also be cool…

mahjongg avatar

Would not do that (sawing off part of the board), with a many-layer board as the PI, chances are big you will creat internal shorts.
Also because its more cost efficient to use an identical PCB for the (announced) Model A+ and the Model B+ I do not expect the PCB of the model A+ to have any “experimenters areas”.
Also the B+ PCB should be final at this stage.

Something I didn’t see mentioned in any of the videos or descriptions above – did some of the status LEDs disappear? They’re labeled ACT, PWR, FDX, LINK and 100 on the Model B. I see ACT and PWR in the upper-left corner in the picture of the B+, but that’s it.

Not that I’ve ever paid that much attention to the LEDs, but I’ve seen them referenced in debugging steps.

Ben Finio avatar

Answering my own question…I spoke too soon – towards the very end of this video (7 minute mark), he shows that 2 of the lights are on the ethernet port itself:

http://youtu.be/KtKSyN0x6sk

So that accounts for 4 out of the 5…

Aardvark avatar

This explains why my local computer shop dropped the price on model B’s about three weeks ago from USD$39.95 to USD$29.95 as well as various cases. I like the extra USB ports as two can be problematic without an external hub. At the moment, I have enough B’s to keep myself amused but my next purchase will most likely be a B+.

Liz Upton avatar

Actually, the reason that happened is much more likely to be to do with currency fluctuations; nobody was discounting ahead of time because of B+.

Do the new raspberry work with less temperature?

DRB avatar

All this work seems to be getting in the way of the Pi Education Fund opening for applications :)

AndrewS avatar

AFAIK the RPF is technically split into an “engineering half” (e.g. http://www.raspberrypi.org/products/ ) and an “education half” (e.g. http://www.raspberrypi.org/resources/ and http://www.raspberrypi.org/picademy/ ).
But it’s still a relatively small team so there’s probably some overlap ;)

AndrewS avatar
ACW avatar

Can you PLEASE mark the precise location of the 40-pin header on the mechanical drawing…maybe the co-ordinates of the PIN 1 pad?

beta-tester avatar

hi, does the model B+ still have the crappy one single lane on the DSI/LVDS (Display Serial Interface)?
so you still can not connect an LCD Display directly to it – because todays lcd Panels are using Minimum 2 and more common using 4 lanes.

unbelevable, that it was forgotten to connect all four existing lanes of the PI to the connector – so the Interface is in fact not usable for anything.

beta-tester avatar

oops, shame on me. i forfot to tell, that on the other Hand i very like the new model B+.

Martyn Jones avatar

I don’t think the education community which the Foundation was originally targeting gives a hoot about most of what these comments on either side are ranting on about. It seems that the whole initiative has now been hijacked by hobbyists and fanboys who are just looking for a small and cheap computer on which they can base their next project. Let’s get back to what’s important please – educating kids in computing.

Jane avatar

This is just awesome news. The amazing little RPi just gets better.

I just have to shake my now-greying head at some of these comments. It’s a $35 computer people. It’s a gift to the world. Somewhere right now there is an incredibly gifted child who otherwise couldn’t afford a computer with a RPi. That child is going to grow up and do something that will change life as we know it. He/she doesn’t care about a SATA chip or dual core. That child is just happy that he or she has a computer at all.

That’s what the RPi is all about.

Thanks to the Foundation. I know that this was a lot of hard work and I’m really looking forward to adding another pi to my collection. Great work people!

MW avatar

+1 wholeheartedly agree, though I am often abused for taking the stance that a Pi is adequate as is..

Yes I am now a B+ owner and the evolution is fantastico !

Matthew M avatar

I agree — I was that kid about 30 years ago. Too bad PCs were ridiculously expensive back then. I was introduced to a Commodore 64 when I was 7, and I wanted nothing more than to have hours alone with that machine to write BASIC programs. I guess I’m a born programmer. But I had to wait until I was *15* to get any kind of access to a computer. It was a long wait! I would have loved to have an option like the Pi. I would have sold lemonade for a month to get the $40.

Stephen Pearce avatar

Mine arrived this morning, and I’m now in the process of setting it up.

Few words of praise while I wait for an image to be written to my MicroSD card…

It both looks and feels incredibly well refined, and the build quality is perhaps the best I’ve seen to date. I can’t recall how many variations of the model B I’ve experienced (and later recycled to friends) but I’m pretty certain I’ve seen each of the major Model B revisions.

This is a massive step up from the latest model B, and an even greater step up from the older 256MB variate if you’re still using one.

If you’re looking for a significant upgrade, this is it.

Thanks RS for the ridiculously fast turnaround ;-)

Iain Turner avatar

Ignore the nasty detractors! I am a teacher who has used the Pi (A and B) with Scrtach and then Python to bring propgramming to a whole school full of kids. My own boys use it and I will be laying hands on a B+ as soon as I can.
You guys do FANTASTIC work and those who whinge about not having this and that should fire up the soldering iron and do it themselves.

Thanks for this new release of the Raspberry Pi

I’m very interested to integrate this card in a demonstrator for a project (to be deployed in my customers homes) but I would like to know if there are any qualification certificate/reports available (CE mark, electrical security, etc)? Or qualif planned to be passed?

Thanks

Mine came from RS with a ***Statement of Conformity*** attached to the paperwork..

JulienC avatar

Thanks but I dont think this is what I need.

Is there any CE mark Test Reports available for this new board on the Raspberry foundation side? Do you know to whom I could ask to get these documents? This is mandatory for me if I want to deploy Raspberry in my demonstrator…

thanks

Liz Upton avatar

We don’t share those; you should be able to demonstrate that the device is CE marked, but it’s the legal responsibility of any company making a product with Raspberry Pi inside to do their own CE/FCC testing on their entire product.

JulienC avatar

Thanks Liz,

Of course, we’ll do our own certification for the global product but we would have less tests to pass if we could have Raspberry CE test reports… Why don’t you share these docs? they are a proof of good job!

Julien

James Hughes avatar

I’m not sure that having the Raspberry CE reports would reduce the number of test you have to do yourself. Since enclosures and peripherals can make such a large difference, don’t you have to do all the required tests anyway?

NealB avatar

I have read may postings on the new Model B+ and have been interested on some of the comments. I have had my New Model B+ now for just over a day and feel that some of the comments made by people who don’t have one should read my actual findings.
The new switch mode power supply is much better on the 3.3V – it bounces less and does give some more output current.
The 5V rail is still very much an issue – the supply still goes through a polyfuse which increase its resistance with current follow. Switching 2 small relays, keyboard, mouse sees the 5V rail dropping to 4.6V, this can be overcome by the usual shorting out of the polyfuse.
The new audio & video connector is very nice but if you plug a set of headphones, speakers etc without using a special lead you short out the composite video signal -outch!
The new MicroSD slot is great and very reliable – I’ve repeatedly tested the latching which on some connectors can be week and not hold the card correctly.
I have tested a lot of different add on cards and all worked perfectly.
I have read some people complaining that the extra pins on the new GPIO connector will stop them plugging in things – not the case unless you are using a cheap IDC ribbon cable with extra large retaining clips.
Overall this updated model from what I have experienced is far better than the previous models.

mahjongg avatar

No “outch”, shorting out the Video output when using a stereo jack plug was full foreseen in the design, and has no detrimental effect at all.

mahjongg avatar

and the new polyfuse is now 2Amp instead of the old 1.1Amp one, but you should feed relays from their own external power supply, just as always. For normal USB devices the new polyfuse should not be a deterrent.

NealB avatar

The polyfuse being 2A does not get past the fact that is a polyfuse which has resistance, and hence volt drop. The only difference with the new 2A is the rate of change. The 2 relays in question where used as load, each taking 54mA. The power supply attached was a 5V 4A calibrated supply which takes it out of the equation.

mahjongg avatar

Theoretically off-course you are absolutely right that a polyfuse -must- have a resistance to work, but normally this resistance is so low that at currents below the tripping point the voltage drop will be negligible!

Your comment about “the usual shorting out of the polyfuse.” is far from reasonable, its a very rare occasion that the polyfuse “must be shorted”!

In fact the only time I have hear of such a thing being needed was when the polyfuse was broken (perhaps by being triggered very many times). And also in the time that each USB ports still had its own, (very low rated) polyfuse, but that is the reason why they were later removed.

In fact I have researched which polyfuse has been used in the B+, and came to the conclusion it is the 1812 sized 2.0A hold current BOURNS MF-MSMF200, which according to it’s datasheet has an -maximal- internal resistance at 25 degrees Celsius of just 0.080 Ohm (and a minimal internal resistance of just 0.02 Ohms) Other brands will by nature will have a very similar resistances.

According to you the voltage behind the polyfuse drops to 4.6V, at which point by the way, the new brownout detection circuit of the B+ would turn off the PWR LED, but that is besides the point.

The point is that this means that if the polyfuse is the only cause the polyfuse must have a 5.0 – 4.6 = 0.4 Volt drop across it!
But this logically means that according to ohms law the -minimal- current that must flow through it to cause a 0.4V drop must be I = V / R = 0.4V/0.08 Ohm = 5 Amperes! Thus this is clearly impossible!

The only reason you can see a 0.4V drop appearing on the PI is that somewhere there is a much larger resistance between the PSU and the PI than the polyfuse’s 0.08 Ohm.

I can estimate that resistance value, as you have supplied a rough indication of the current consumption.

I’m guessing the B+ PI uses roughly 500mA (maybe a bit less), each USB mouse/keyboard device uses a maximum of one hundred mA, but most often its half that or 0.1A (100mA) together. And both relays together use (when both turned on) 2 x 0.054A = 0.11A (110mA) and the HDMI port uses another maximal 50mA, so the total current consumption will maximally be 500+100+110+50 = 760mA, that means that the 0.4V drop must be caused by a resistance of about R = V / I = 0.4/0.76 = 0.53 Ohm!

its well known that below par microUSB cables can have several fractions of an ohm resistance, it appears you might use a terribly bad one.

Matthew M avatar

I understand that upgrading the Pi to Dual-core, etc. would require a whole new design, and render much of the Foundation’s work up till now useless. HOWEVER, what about upgrading to 1 GB of RAM? That would vastly improve the “budget PC” experience of the Pi, and it would be completely backwards-compatible. I suppose the question is, does such a System-on-Chip exist?

James Hughes avatar

There are no 1GB compatible RAM chips available, so effectively impossible.

mahjongg avatar

The main reason why a massive performance upgrade is unwanted is because in all probability it would mean that all new software developments would be done with the new performance in mind, and that would leave all the millions of previous PI owners in the cold, as they would not be able to use such software. So they all would be forced to upgrade!

This may be a good policy for a commercial company, but not for a foundation like the RPF, that wants their users to have many years of profit from their PI’s without being forced to upgrade.

SiriusHardware avatar

If this was going to happen it would have happened with the original 256MB Pi, but I haven’t seen any sign yet that users of those (I still have one myself) are being forced to upgrade by writers / producers shutting out the 256MB Pi.

However, since I also own a 512MB model I’m bound to say that the performance of the 512 model is considerably better for things which involve using it as a desktop PC – so if a 1GB version magically appeared (and I know there is no such SOC-TOP Ram available, so this is purely hypothetical) then I would not grumble too much about the opportunity to add a 1GB Pi to my collection.

Matt Smith avatar

If your like me and have spent the few days crying because your B+ has a USB ethernet issue. Plug the SD into your old pi and do a

sudo apt-get update
sudo apt-get upgrade

and then smile like a smiley person

Michele avatar

0,5-1W just only replacing linear regulators!?
If power consumption will be less 1W it would be great.
By the way, would it be a way to “disable” sameway video output to further reduce power?

mahjongg avatar

The GPU already auto-magically turns off parts of itself when they are not needed, that is why, for example, playing full HD video’s slightly increases power consumption.

In a few months time a Plus version of the model A will be released, identical to the B+ but with the same stuff removed as the model A, so without the LAN9514 chips, but with the new switching power supplies. The A+ will be the model for people who need very low current consumption.

Shannon Spurling avatar

B+ is passing, but I need an A… Seriously, where can you get a model A in the US?

James Hughes avatar

Should be a new production run of A’s soon – all manufacturing capacity has been on the B+ in recent weeks since demand for that is so much higher. Once the demand has dropped to sane levels, then A production can be restarted.

Steve Drain avatar

Will that be A or A+? The original A still has the advantage of back-powering from the USB. For stripped-down projects that is very convenient.

SEDur avatar

Beautiful… Still no thoughts on upgrading to gigabit ethernet yet?

mahjongg avatar

That too would require a new SoC.

Ian avatar

Hooray: 4 USB ports. It will stop having to choose what to plug in / using a hub quite so often.

It looks like the only reasons for going for a B now are that a B+ won’t physically fit in something or you have a pile of SD cards because..

Boo: moving to microSD. You can fit a microSD card into an SD slot with an adaptor, but you can’t fit an SD card into a microSD slot even with a saw. (Well, not if you expect it to work anyway!)

The change I would have liked to have seen was the ability to plug in a VGA monitor. There are an awful lot of VGA monitors out there that can’t do DVI and the Gameduino shield for the Arduino shows it’s not hard to do VGA at a fixed resolution and frequency.

Hmm: obviously too much could not have changed if it is still to be a ‘B’. But it’s interesting to see so many ‘but it couldn’t have been an ARM7-based SoC’ posters use the because of how much work has been done on ARM6‘ arguments. As at least one person has said, it’s inevitable that a future Pi will go ARM7, and that work will become ‘legacy’ before too long.

mahjongg avatar

The current Broadcom SoC cannot, and never has been able to support VGA output signals, so to create VGA signals a HDMI to VGA converter would have to be built in, and it would have increased cost and power consumption of the PI to similar levels as for people who now use an external HDMI to VGA adapter, but for everybody!

It already was quite easy to use a HDMI to VGA adapter, although using many different models makes it a bit more difficult to find the right settings (if any were needed).

One of the improvements of the model B+ is that the need to use an externally powered VGA adapter has been removed! So you can now use the more cheaper HDMI powered models, which means no more extra cabling and supplies!

Its possible the swag shop will start to sell an “official” HDMI to VGA adapter, now the use of HDMI powered models has been officially endorsed. And with just one universal model setting it up will become much easier, especially if they manage to find a cheap model that does not need any manual setup!

MW avatar

Actually ARMv8-64 is more than likely for next generation Pi, ARMv7 is getting old so if the RPF had changed at this point, then would have to change again in 2 years or so, what a waste of time, money and resources. Also the price point and choice of SoC’s is more favourable now than it was five or so years ago and in real terms will get cheaper.

I wish people would think about the future before pulling ideas out of the air and jumping on a meaningless band wagon.

Regards VGA, well Dvi has been on monitors for a decade or so and digital is easier than analogue to implement in boards considering the price point.

Last but not least I do have B+ and the silly USB Hub back powering has gone which is great. The transformation compared to my first Pi bought 2 years ago is absolutely amazing and can not wait for Maynard to give it the final polish !

Just curious about the IDE cable on the 40 pin gpio. Looking through my stock of cables I see some of them had a pin position blocked out.. the ones with 3 sockets on them are all open but I am afraid to use any of these because I don’t want to short out the board.. is there an article available on how to make use of the old IDE cables we have lying about or should one avoid doing this? .. thanks

mahjongg avatar

Most often pin-20 is blocked, but on the Model B+ PI, pin-20 happens to be one of the GND pin’s so potentially you do not need it and you can cut it off with a side cutter.

Johan Adler avatar

I have no trouble using an external USB hub, which can also provide power if needed, so two extra USB ports will not do much for me. (By the way are they native or is there a USB hub on the board? More native USB connections could improve speed, a hub does not.) For me personally two Ethernet connections would be more useful.

In my humble opinion the switched regulators should have been there from the beginning, why waste power and generate heat by using old LDO regulators?

Regarding power I would really, really like a normal power socket, that would tolerate a wider span of input voltage. Why not something like the Olimex Duino series? Having support for a rechargeable battery would give a simple UPS functionality.

Actually there is at least one good reason to use linear regulators rather than switching regulators on equipment, and that is to minimise the amount of broad-band RF noise that the unit generates. Switched – mode power supplies are generally a nuisance to HF / Shortwave reception, so anyone using a Pi in conjunction with an HF radio receiver (for ham radio purposes, etc) might very well find that the old ‘B’ is still a better board for that purpose.

Found a case you can print. http://www.thingiverse.com/thing:396858

While you were doing the board upgrade you could have integrated a wifi adapter. I miss it a lot…

Ben Nuttall avatar

Could have, but not at the crucial price point. Not everyone needs wifi, and if they do – they can use one of the four USB ports for a wifi dongle.

Also, you could say that about any feature. What’s important to you is not necessarily important to others. Our focus is on education.

Graham Toal avatar

OK, I’m seeing the pattern here – so how long is it until you come out with the “Raspberry Pi Master 128” :-)

Cole Milne avatar

Very exciting! I have a the Model B Revision 2 and I just might pick this one up because of the 14 Extra GPIO Pins and the Micro SD Slot!

Long Zheng avatar

Are the B+ models made in the UK?

James Hughes avatar

Yes

Henry Pham avatar

Now, all we need is Raspberry Pi Model B+ Heatsinks

James Hughes avatar

I hope you are being sarcastic….

Alex Cheung avatar

Will Model B+ be released by Egoman of China? Many thanks.

Miquel Bosch avatar

Right now there isn’t any photo of the Raspberry Pi B+ in Wikimedia Commons to use in the wikipedia’s articles. Is the first image in this article licensed as CC BY-SA so I can upload and use it?

Liz Upton avatar

These pics from Adafruit are CC BY-NC-SA – have at it! https://www.flickr.com/photos/adafruit/with/14647185751 (They’ve got a proper studio setup, which we don’t have at the minute, so their pics are rather more *wonderful* than ours are!)

Miquel Bosch avatar

The CC BY-NC-SA license doesn’t comply with de wikipedia standards, it should be CC BY-SA or CC BY, could you or the community share some pictures? http://commons.wikimedia.org/wiki/Commons:Contributing_your_own_work Thanks ;)

nathanael avatar

How about a T-shirt with just a photo of the B+ or the track lay-out and silk-screen on? That would be cool as it would make the wearer look like a robot.

Fourdee avatar

Bit of a disappointment if i’am honest. It feels like a massive waste of resources with little improvement to the core of the unit whilst ignoring the main issue with the PI.

Its time to move on, the raspberry Pi is old old tech. All you had to do is change the cpu to dual core to keep the product with the times.

The improvements to the “audio noise” surely will only apply to those who dont use the digital HDMI output.

The microSD change is welcomed, but without changes to the CPU, it just feels a waste of production runs.

Dual Core + USB3 + Gigabit Ethernet = job done. Say hello to Raspberry Pi 2.0. Thats what we crave, please make it and let this old and great product rest in peace.

And yes, my Model B 256mb Pi is still alive and kicking :)

The product announcement said it all:

This isn’t a “Raspberry Pi 2″, but rather the final evolution of the original Raspberry Pi.

as for the magical Raspberry PI II, it well known it wasn’t in the picture, literally from the sticky “When will there be a NEW Raspberry Pi?”

There is no ‘new’ Raspberry Pi expected in the near future.*

Eben Upton, Founder, has stated in public that he would expect a NEW board between two and three years from now (Sept 2013). In all likelihood,this would be a device with a new SoC with more power and more memory, and perhaps other features yet to be decided.

I (personal opinion) expect that the upgrade path to any new device will be simple, and code will be compatible between devices, to ensure smooth transitions to any new device.

In the meantime, there will continue to be new revisions of the current device (same SoC) as and when they are required and are cost effective. Again, there will be no compatibility issues between device revisions.

The Foundation are putting a lot of money in to optimising code to run on the Raspberry Pi, both at the graphics level (Weston/Wayland and others) and the apps level (Scratch and others), which will ensure the device remains competitive over its lifetime.

* New does not include B+. As stated in the Model B+ product announcement, this is the final evolution of the original Raspberry Pi design.</cite)

recent predictions place the PI II somewhere in 2017.

As for "a massive waste of resources with little improvement", and "Thats what we crave" I could not disagree more, this update was exactly what was needed for the raspberry PI, the improvements are enormous, and do not make all the old Raspberry PI's obsolete overnight, which is probably the most important point.

If you want a "Dual Core + USB3 + Gigabit Ethernet" system, you can buy that now, but it won't be a PI, and you can expect to spend a lot more than $35 for it.

its not in the best interest for the RPF's goal to throw away two years of development of a system meant for computer education (and anger three million current PI users) by making it obsolete.

nathanael avatar

Never say never – some of these simple improvements were publicly dismissed in the forum by certain individuals speaking on behalf of the foundation. The need to clear old stock requires the foundation to keep forthcomming hardware releases under wraps. The pi created a market and now has competition. I anticipate further hardware releases.

Clive Beale avatar

It’s a computer for the price of an Ethernet adapter. It does what it was designed to do and way more. Your disappointment is misdirected.

Fourdee avatar

– Ethernet adapters are £5, not £35
.
– The Model B does exactly the same as the model B+, so why upgrade?

– why burn a whole new fabrication process and resources on adding 2 more usb ports. Especially when the majority already use a USB hub for their Pi’s?

– Why should a Model B user upgrade to a B+? Only the “die hard” Pi fans will. Everyone else (eg: me) are waiting for a more valid reason to upgrade.

I respect what the foundation has already done with the Pi from day one. But if they want to reach and replenish their current market, its time to “move on” and stop rehashing old equipment.

Stick a Dual Core chip on the current Pi board. Then i’ll gladly buy more Pi.

salman avatar

“Ethernet adapters are £5, not £35”
Tell that to Apple ;)

“The Model B does exactly the same as the model B+, so why upgrade?”
Because it doesn’t do the same.

“Why should a Model B user upgrade to a B+?”
They shouldn’t unless they want or need to.

“why burn a whole new fabrication process and resources on adding 2 more usb ports.”
This is a straw man.

“I respect what the foundation has already done with the Pi from day one.”
And yet you don’t seem to understand what they are trying to do.

“Stick a Dual Core chip on the current Pi board.”
It wouldn’t work.

Fourdee avatar

“Tell that to Apple ;)”
Sorry, android user here.

“Because it doesn’t do the same.”
Those two extra usb ports make all the difference.

“They shouldn’t unless they want or need to.”
Thinking of sales, market.

“This is a straw man.”
Scarecrows are now involved in fabrication design and implementation?

“And yet you don’t seem to understand what they are trying to do.”
Clearly, not meet their customers demands, ignoring the vast requests for a Pi 2.0.

“dual Core chip, It wouldn’t work.”
Make it work by spending less time on a rehashed B+, which in my opinion isnt worth the investment based on the same ARM cpu that desperately needs leaving alone?

Disappointed, yes, hence my annoyed posts.
So much potential for the Pi 2.0, yet simply ignored by the foundation for side products to dwell on old tech.

James Hughes avatar

Hmm. You may be disappointed, but the sales suggest that most people are not. You really really need to actually think about this a bit more. Just because what you want isn’t what is for sale, doesn’t meant that what is for sale isn’t the right thing overall.

You have basically fallen in to the same erroneous mindset of all the other ‘needs to be better’ posters. They also clearly have not given this enough thought, whereas the Foundation has thought about it.

The point being, right now, it doesn’t need dual or quad cores, it doesn’t need 1GB RAM, it doesn’t need gig ethernet.

As for ignoring the ‘vast’ requests for Pi 2.0. What vast requests? A few internet commentators don’t count. Really, it is only a few in comparison to sales numbers. Have you got demand numbers? No, because you have made an assumption that everyone wants and needs these higher specs and that is NOT the case, as shown by the very large sales of the A/B and now the B+ (and interestingly, the very very low sales of the BB and all of the faster devices out there)

adavis avatar

My! What a spoiled young man! (I’m guessing young due to your entitlement and lack of understanding of how the electronics industry works etc — if you are over 25 then you should be doubly ashamed of your self-absorbed trolling)

Jim Kopps avatar

I am having an issue getting my B+ to boot from a 16GB Sandisk Ultra Plus micro-SDHC. Is anyone aware of a size limitation on the micro-sd card?

Liz Upton avatar

Are you using the newest firmware?

Jim Kopps avatar

Trying to use noobs 1.3.9 Freshly downloaded.

Sreekanth Arun avatar

WOW!!

Last Sunday i bought model-B :(

Phil Balaam avatar

The I2S connector seems to have gone on the B+ :-0
Does this mean that you can no longer use extarnal audio DACs with a B+ or can you still get to the I2S bus somehow.

This will be a terrible blow to all the people wanting to use the pi as a high quality media player because the onboard audio (even on the B+) just isn’t good enough!

Liz Upton avatar

Have another look at the new GPIO pins.

mahjongg avatar

its actually simpler to connect a random codex chip than the original B!

That is because the interface now requires just one connector, instead of two!

Thats because the B’s P5 connector only contained I2S signals, and most codecs need both I2S AND I2C (12S four sound, and I2C for configuration and control), and now the new 40 pins connector offers both!

Thats why Wolfson had to use expensive pogo stick connectors, in addition to a 26 pins header for their “soundcard”.

glnds avatar

First benchmark results Raspberry Pi B vs B+: no difference in performance but quite a huge difference in power consumption! The benchmark results can be found here: http://gleenders.blogspot.be/2014/07/raspberry-pi-b-vs-raspberry-pi-b.html

nathanael avatar

thats great for self-contained or always-on applications (like a robot or server)

Noob avatar

Got a new B+ with NOOBS and PiBow, when will it arrive? (Says: Ships next working day, I put the order on around 7pm friday Hong Kong Time)

Noob avatar

Monday, I think. but I hope it’s shipping friday/now!

Matt avatar

Just a quick observation of the style employed for your bullet points in what has been improved on the B+: The red minus “-” symbols as the bullet points, indicate a negative, and imply that there would be green plus “+” symbols to complement them. This is merely a cosmetic observation of this article :)

Ahmad avatar

Hello all.

I can’t seem to find one with international shipping. Do you know one that ships internationally (outside U.S and EU) ?

Thank you.
Regards.

Donald avatar

I noticed there are some model B+ labeled v1.1 and v1.2 so I was wondering what, if any, are the differences between the labels or is it simply cosmetic? The only thing I really noticed is the display DSI and camera CSI brackets are either white or black (white on v1.1 and black on v1.2)

none avatar

I still need A Intel Core i7 @ 4.7GHZ, built in nuclear reactor, toaster oven, and a skynet controler.

Kasun avatar

Hi,

Can someone tell me whether i can use Micro SDHC 32GB card with model B+?

Liz Upton avatar

Yes, you can. If you’ve got other questions, swing by the forums (link at the top of the page), where 100,000 users are waiting to help you out!

Kasun avatar

Thanks a lot Liz

Reidmere avatar

My first thought with this was “Does it have a better fuse to allow more input to supply those extra USB ports?”.

After that, my next question was “Based on the extra GPIO pins, do you plan on releasing some form of adapter board to allow ribbon connection of the PiFace?

My design idea would be to create something like the PiRack, with 2 original RPi GPIO outputs, and 2 modern outputs.

I would love these questions answered!

JulienC avatar

Thank you James for your answer.

Sorry for the delay, I just come back from holidays!
I confirm that if I have Raspberry CE test reports (not only certificates), there will be less tests to pass for my product. This is what I’ve been said by the certification authority in France. That is why I ask you for this test reports.

Thanks again for your help.
Julien

I’m not sure that having the Raspberry CE reports would reduce the number of test you have to do yourself. Since enclosures and peripherals can make such a large difference, don’t you have to do all the required tests anyway?

Liz Upton avatar

We do not share that information; you are liable for your own certification.

Max Lee avatar

Anybody know if Raspberry Pi model B+ can support direct plug in of a 3G dongle WITHOUT having the Powered USB Hub? Thank you.

Justin avatar

Does the B+ have POE?! This would be a GREAT feature for this little system.

Thanks,
~Justin

David Braziel avatar

I have the raspberry pi model b running ultimate raspbian, but i just recently bought the model B+ and am trying to install the same version of ultimate raspbian and it won’t boot. Could you reply back giving some insight and maybe explain why it’s not booting.

James Hughes avatar

Does it boot with the standard Raspbian? Is so, you should approach the Ultimate Raspbian people to get an updated package.

Ben Nuttall avatar

Not so ultimate after all, eh?

Grégory avatar

You said in July “for our industrial customers we’ll be keeping Model B in production for as long as there’s demand for it.”
Today Model B is out of stock until March 2015 (RS and Farnell), i need to buy 1000 units, where is it possible to reach people in charge of Industrial customer ?
thanks a lot

brenden avatar

I’m in the same boat. Need 5K Model Bs and availability is none. It will be good to have point of contact for industrial customers.
