New product: Raspberry Pi Zero 2 W on sale now at $15

It’s been nearly six years since we unleashed the $5 Raspberry Pi Zero on an unsuspecting world. Of all the products we’ve launched, Zero is still the one I’m proudest of: it most perfectly embodies our mission to give people access to tools, and to eliminate cost as a barrier. We’ve sold nearly four million units of Zero, and its $10 wireless-enabled big brother Zero W, and they’ve made their way into everything from smart speakers to hospital ventilators. But where our larger products have grown steadily more powerful over the years, we’ve never found a way to pack more performance into the Zero form factor.

Until today.

Raspberry Pi Zero 2 W

Priced at $15, Raspberry Pi Zero 2 W uses the same Broadcom BCM2710A1 SoC die as the launch version of Raspberry Pi 3, with Arm cores slightly down-clocked to 1GHz, bundled into a single space-saving package alongside 512MB of LPDDR2 SDRAM. The exact performance uplift over Zero varies across workloads, but for multi-threaded sysbench it is almost exactly five times faster.

Raspberry Pi Zero 2 W specifications

Here are the highlights:

  • Broadcom BCM2710A1, quad-core 64-bit SoC (Arm Cortex-A53 @ 1GHz)
  • 512MB LPDDR2 SDRAM
  • 2.4GHz IEEE 802.11b/g/n wireless LAN, Bluetooth 4.2, BLE
  • 1 × USB 2.0 interface with OTG
  • HAT-compatible 40 pin I/O header footprint
  • MicroSD card slot
  • Mini HDMI port
  • Composite video and reset pin solder points
  • CSI-2 camera connector
  • H.264, MPEG-4 decode (1080p30); H.264 encode (1080p30)
  • OpenGL ES 1.1, 2.0 graphics

If a lot of this looks familiar, it’s because Simon Martin, who designed both Zero 2 W, and the RP3A0 package that powers it, has been able to squeeze all this extra performance into the original Zero form factor. Almost all cases and accessories designed for Zero should work perfectly with the new board, including our own case and selection of cables.

PHENOMENAL COSMIC POWERS…itty-bitty living space!

Packaging magic

The principal barrier to creating a higher performance Raspberry Pi Zero has always been form-factor: with a tiny board, and single-sided component placement, there is no physical room to accommodate both the main system-on-chip (SoC) and a discrete SDRAM package.

Like Raspberry Pi 1, Raspberry Pi Zero and Zero W are built around the Broadcom BCM2835 SoC. This neatly sidesteps the problem by using package-on-package (PoP) technology, in which the SDRAM package sits directly on top of the SoC.

BCM2835 and 168-ball LPDDR2 PoP memory

PoP is an elegant solution if the silicon die in the SoC is small enough to fit in the cavity between the balls of the SDRAM top package. Unfortunately, as Broadcom added first a quad Cortex-A7 (to create BCM2836), and then a quad Cortex-A53 (to create BCM2837), the die outgrew the PoP cavity. From Raspberry Pi 2 onward, we use discrete SDRAM, but this option wasn’t available to us for a future Zero.

But there’s another way to avoid discrete SDRAM, and if you’ve been following Raspberry Pi since the start, you’ve met it before. Back in the day, BCM2835 had a slightly evil twin, BCM2763, which integrated a 128MB SDRAM die directly into the package along with the SoC die; this arrangement is known as a system-in-package (SiP). BCM2763 was intended for use as a graphics coprocessor for mobile phones, and powered the original Raspberry Pi prototype we demoed back in 2011.

BCM2835, but with a goatee

Simon, who designed the BCM2763 package at Broadcom a decade ago, now works at Raspberry Pi. In between designing the official mouse and keyboard, the High-Quality Camera, and Raspberry Pi 400, he found time to create RP3A0, a modern SiP which combines the BCM2710A1 die used in BCM2837A1, a 4Gbit Micron LPDDR2 die, and the decoupling capacitors required to smooth the core supply voltage.

RP3A0 system-in-package

Never one to pass up an opportunity for artistic expression, Simon even managed to squeeze a very low-resolution Raspberry Pi logo into the package ball-out, as you can see from this package and X-ray image.

Not the smallest Raspberry Pi logo, but possibly the lowest resolution

PCB magic

Thermals are a challenge when packing more performance into a small package: can we dissipate the heat generated by the faster processor? In common with other recent Raspberry Pi products, Zero 2 W uses thick internal copper layers to conduct heat away from the processor. If you hold a Zero W and a Zero 2 W in your hands, you can really feel the difference in weight.

All this extra copper translates into higher sustained performance: we’ve found that in a 20C ambient environment, an uncased Zero 2 W can run our favourite LINPACK linear-algebra stress test indefinitely without throttling.

Sealed wireless in a can

Next to the large RP3A0 package, you’ll find a large metal shield can, which covers the wireless circuitry on the board and protects it from external interference. Like all Raspberry Pi products since 3B+, Zero 2 W has FCC modular certification, which reduces the compliance workload involved in incorporating it into an end product.

Shield can can shield

New Raspberry Pi Zero 2 PSU

To accompany Zero 2 W, we’re also launching a new official USB power supply. This closely resembles the Raspberry Pi 4 PSU, but with a USB micro-B connector in place of the USB-C connector, and with a slightly reduced peak current rating of 2.5A. Even this is overkill if you’re powering a Zero 2 W, but it comes in handy if you want to power a Raspberry Pi 3B or 3B+.

BS 1363 FTW

The PSU costs $8, and is available in with the following plug types: US and Canada (type A); Europe (type C); India (type D); UK (type G); and Australia, New Zealand and China (type I).

Raspberry Pi Zero 2 W availability

Today, Raspberry Pi Zero 2 W is available in the United Kingdom, the European Union, the United States, Canada, and Hong Kong. We’ll add new countries as we complete our radio compliance work, with Australia and New Zealand coming up first in November.

Sadly, Zero 2 W isn’t immune to the current global semiconductor shortage. We expect to ship roughly 200k units this calendar year, with a further 250k to follow in the first half of 2022.

Frequently-asked questions

We’ll update this list as we answer questions in the comments, but here are a few to get you going.

Are you discontinuing Zero and Zero W?

No. We seldom discontinue products, even where they have been superseded by more modern product at the same price point. Zero 2 W is $5 more expensive than Zero W, and joins the Zero family as a third member.

Note that Zero and Zero W are currently experiencing supply constraints in the context of the global semiconductor shortage. We hope that this will be resolved in 2022.

Will there be a version of Zero 2 W with 1GB of SDRAM?

No. 1GB LPDDR2 monodie are not available, and producing a SiP with two stacked SDRAM dice would be very challenging.

What do the markings on RP3A0 mean?

RP3 is the name of the package. A0 indicates that this is the first version of the part. AU indicates that the package uses gold (as opposed to copper) bond wires.

The 4-digit code is a manufacturing date, expressed as a year and a week number. Amusingly quite a lot of units were manufactured in week 41 of 2020, yielding the misleading code “2041”.

The 6-digit code is an order date, expressed in the format YYMMDD.

How long will Zero 2 W remain in production?

We aim to keep Zero 2 W in production until at least January 2028.

Credits

Products like Zero 2 W draw on the skills of the entire Raspberry Pi team. Aside from Simon, particular thanks are due to Roger Thornton for compliance, Phil Elwell for firmware, and Mike Buffham for commercials.

I’d like to thank our partners at Broadcom, Micron and ASE for their help in making RP3A0 a reality. Like most Raspberry Pi products, Zero 2 W is built at the Sony UK Technology Centre, in Pencoed, South Wales: we couldn’t do this without them.

The blog post only says that this psu is overkill for the zero2. But how many amps does the zero2w need?

I’m currently using a zero1w on a samsung tv that has a 1A USB port. Sometimes i connect it to a Motorola Atrix lapdock. Both have no problems powering the zero1w. The lapdock struggles with everything above a Pi2B.

I think the zero2 could work with the lapdock. But would it also work on the 1A USB output of my tv?

I agree 100%, what the focus should be is server OR client:
– To me the original Raspberry 2 still holds the server crown in Gflops/W with the IO limits of the SD card.
– Raspberry 4 has an underdimensioned GPU compared to the CPU but can be used as a calculation server for heavier (non SD card) related duties.
The missing device is a Zero with more powerful GPU than the Raspberry 4!!!

Yup, just you (the the guy above!). People have been asking for a LONG time for a more powerful Zero. And here it is! As for 512KB of RAM being a limitation – just write better code! You only need huge amounts of RAM for things like web browsers, and for the use cases Zero’s get used for, that not all that common. Zero’s get used for robots and get stuffed in to small devices to provide processing power, not desktop capabilities.

It isn’t about the form factor for me. To me, the whole point of the Zero has been as a cheap replacement for a development Raspberry Pi. You develop a project with a $35+ board and you want to keep it, but you also want to move to a new project. So you buy a $5+ RPi Zero and swap in the SD card.

I don’t think it “requires” a large amount of extra power, it is only a bit more hungry at idle and you can lower it by switching cores off. This means if it is doing a similar kind of workload to an older zero W then the power won’t be a great deal more.

But, if you did want to work the thing harder than the original zero was capable of, then it would have that extra grunt – which would require more power, and it is available if you need it.

Is the raspberry pi open hardware ?
Do you have gerber files, pick and place files and BOM files that I could load up at my favourite PCB fab (starts with J) and get a Pi this way ? Are the components widely available or are they only available to the RPi foundation ?

I ask mostly because I would like to make minor changes to the RPi02W, namely add a full sized HDMI connector and turn it into an HDMI dongle. Also I would like to make a slightly longer version with a USB hub on board. And lastly I would like to make a slightly longer version with a usb hub and an ethernet port and an hdmi usb input chip.
And then republish those new gerber and etc. files as new open hardware clone Pi variants.

The decision to stick to the microUSB ports instead of USB-C is compatibility-related, cost-related or something else entirely is the reason?
Just wondering about that

Reply to TadeusTaD

Alasdair Allan

USB-C is more expensive, and this is a Raspberry Pi Zero, and expensive matters when we’re trying to squeeze everything into the price point. But beyond that, and probably the crucial thing is board space, USB-C takes more board space and there really wasn’t any to spare. Simon had to squeeze things really hard to get everything into the same form factor.

Compatibility is important – going to USB C would mean Zero cases would no longer fit, and you could not use a 02 as a drop in replacement for a 0.

Unfortunately, the idle current for the Zero 2 W is slightly higher than the original Zero, and powering a Zero from a laptop or TV USB was pretty marginal depending on how it was loaded. You’ll need a separate power supply.

It wasn’t technically feasible to stack two 512MB DRAM dies on top of the CPU die for architectural reasons, and a 1GB monodie isn’t available, and if it was available it would be too large and would therefore take up too much board real estate, so we’d be unable to maintain the Zero form factor.

The CM4 (and 1,3) allow access to the 4 lane CSI. Unfortunately, adding it to the Zero or others in the Pi range would mean a change to the connector and break a lot of backwards compatibility. It would also be very difficult to route on a PCB the size of the Zero.

How about the power consumption? Can this Pi Zero be powered with 5V/1A or 5V/2A? I ask because I want to use it on the go

Reply to Michele

Alasdair Allan

We recommend an external power supply as the current draw of the Zero 2 is higher than the original Zero. However the minimum size of your power supply will depend on your use case, there have been some good comparisons of power consumption by folks like Jeff Geerling, who also look at disabling cores to reduce the power budget, as well as Gareth Halfacree at Hackster.io.

That Pi logo-shaped logo in the “package ball-out” is indeed art. I declare Simon Martin to be both an artist, as well as a scientist.
Thanks so much for maintaining the same form factor!
For that price, it seems to me pretty much a no-brainer that anyone with a project already having a previous Pi zero would just toss in this newer one instead.

Congratulations on solving the issues around upgrading the Pi0. This now means that *every* Pi product line has a 64-bit capable upgrade path.
The new PSU is also and interesting addition to the stable.
A bit more on power requirements would be welcome.

If its based on the Pi3 die, will it use Pi3 kernels and kernel modules?

Reply to Glenn

Alasdair Allan

Yup. The new RP3A0 SiP looks a lot like the BCM2837 to the OS.

Hi
How much power needed in full load(heavy cpu benchmark)? I mean 5v 2.5A psu is really required or it’s just an over measured psu which is already in stock? For battery usage perspective. Thanks for reply.

We recommend our own power supply. However, there have been some good benchmarks of power consumption of the new Zero 2 by folks like Jeff Geerling, who also look at disabling cores to reduce the power budget, as well as Gareth Halfacree at Hackster.io.

Nice job, I was hopping to see 1GB or even bigger RAM options. Right now this will be a big improvement in 3D printer’s setup with Octopi. Again, thanks for your work.

Reply to Diomedes Dominguez

Alasdair Allan

It wasn’t technically feasible to stack two 512MB DRAM dies on top of the CPU die for architectural reasons, and a 1GB monodie isn’t available, and if it was available it would be too large and would therefore take up too much board real estate, so we’d be unable to maintain the Zero form factor.

Anyone know the Zero 2 W has AES crypto enabled or was it still not licensed from ARM?

WAAA! Imagine jumping into a bowl of raspberries now; imagine the confusion with numbers. Raspberry Pi 02, 0-2, no zero two.
Thanks for the periodic shot of dopamine.

Looks great. I hope I can actually find one. Does this run .NET 6?

Reply to Ronald Walcott

Alasdair Allan

Probably a question for Microsoft rather than us, but it should do? Looking at their site .NET 6 as Linux Arm binaries, so it should be fine. There seem to be plenty of installation HOW TOs around for Raspberry Pi!

It was really hard to squeeze things in, and keeping the overall form-factor was important.

Great news – the Pi Zero W is phenomenal so it’s great to see it updated. Is the existing USB OTG support maintained? I found it an incredibly helpful bit of functionality. The existing Pi0W does the job nicely for me from a processing perspective so I’ll probably keep the lower thermal output of that but it’s great to have options of higher power with this Pi02W.

Yes! The board has a USB OTG port.

Yes. I would suggest making sure the OS is up to date, just as a general housekeeping rule, but yes.

When will the raspberry pi run BSD family operating systems?

Reply to Jz80

Alasdair Allan

Sounds like a question for the folks at BSD rather than us, we have our own excellent operating system which runs perfectly on the new Zero 2. But as the RP3A0 uses the same silicon as the Raspberry Pi 3 it shouldn’t take them too long if it doesn’t work out of the box.

Will the Pi Zero 2 reboot when you plug in a USB peripherals when the device is already on like the older Pi Zeros or was the USB circuit fixed?

Reply to Steve

Alasdair Allan

Sounds like you were powering your original Zero with a power supply that wasn’t up to the job and wasn’t providing the board with enough current. Your experience isn’t typial! We recommend our own 12.5W Micro USB Power Supply.

It has been specifically designed to provide a consistent +5.1V despite rapid fluctuations in the current draw. Those fluctuations in demand are something that happens a lot when you’re using peripherals with your Raspberry Pi, and they’re something that other supplies — which may well have been designed to provide consistent current for charging cellphones — usually don’t cope with all that well. Our supply also has a captive (attached) micro USB cable, which means you can’t inadvertently use a poor quality cable, something that can be an issue with other power supplies.

This is a big upgrade for the Zero, but as I explain my first impressions, the original zero still shines in some use-cases.

Why didn’t they go with USB-C????

Reply to ilium007

Alasdair Allan

USB-C is more expensive, and this is a Raspberry Pi Zero, and expensive matters when we’re trying to squeeze everything into the price point. But beyond that we wanted to maintain the form factor of the original Zero.

I see from previous comments that you have no plans for a non-W version, which is a shame. Is there at least the ability to completely isolate the wireless module on the Zero 2 W so it draws no power and I can pretent it doesn’t exist!

Thinking cap on. I think RPiT said that it wasn’t possible to put more than 512MB of RAM on the board becuase it would be too big for the PoP and there’s no room on the board for a discrete RAM chip. What if the wireless chip was removed though – would that theoretically leave enligh space for a discrete RAM chip? I appreciate we’re entirely talking about technical theory – in commercial reality the product would also have to be popular enough that it pays for itself.

As long as you use the appropriate micro-USB to full-size USB adaptor https://www.raspberrypi.com/products/micro-usb-male-to-usb-a-female-cable/ it works fine with USB hubs. But for anything more than just a keyboard and mouse you might need to use a powered hub.

I’ve noticed that the dimensions of the cm4 and pi02w are very similar. Is it possible hat if the io holes were scrapped, that you could put the internals of the cm4 into the form of a pi zero?

That’s not a Zero 2W – it’s the prototype Raspberry Pi from 2011. Which we refer to as Zero 2W’s evil twin – hence Eben’s crack about a goatee.
