The Raspberry Pi Foundation released the Raspberry Pi Zero 2 W on October 28, 2021.
The Raspberry Pi Zero 2 W uses the BCM2710A1 of the Raspberry Pi 3 as the SoC. The ARM core is clocked slightly down to 1GHz, bundled with 512MB of LPDDR2 SDRAM in a very space-efficient way. The performance gain of the Raspberry Pi Zero 2 W varies by workload, but for multi-threaded sysbench it is almost 5x faster than the previous generation Raspberry Pi Zero.
Raspberry Pi Zero 2W Specifications
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 port with OTG
HAT-compatible 40-pin I/O header footprint
MicroSD card slot
Mini HDMI port
Composite video and reset pin solder joints
CSI-2 camera connector
H.264, MPEG-4 decoding (1080p30); H.264 encoding (1080p30)
OpenGL ES 1.1, 2.0 graphics
The new Raspberry Pi Zero 2 W is compatible with previous Raspberry Pi Zero accessories, including cases, cables, and more.
the art of encapsulation
The main factor limiting the performance of the Raspberry Pi Zero is the form factor. Due to the extremely limited size of the PCB, there is not enough physical space to accommodate the SoC chip and SDRAM package.
The Raspberry Pi Foundation designed the RP3A0 system-in-package. The figure compares the past and present encapsulation modes.
Can we dissipate the heat generated by faster processors?
Like other Raspberry Pi products, the Zero 2 W uses thick internal copper layers to conduct heat away from the processor.
If you're holding a Raspberry Pi Zero W and a Raspberry Pi Zero 2 W in your hand, you can really feel the difference in weight.
We found that the caseless Raspberry Pi Zero 2 W could run our favorite LINPACK linear algebra stress test indefinitely without overheating at 20 degrees Celsius.
The Raspberry Pi Zero 2 W is currently available in the UK, EU, US, Canada and Hong Kong. Sadly, the Raspberry Pi Zero 2 W is not immune to the current global semiconductor shortage. The Raspberry Pi Foundation expects to ship about 200,000 units this year, and another 250,000 units in the first half of 2022.
FAQ
Will the previous Raspberry Pi Zero version be discontinued?
Won't. The Raspberry Pi Foundation rarely discontinues products, even if they have been replaced by more modern products at the same price point. Zero 2 W joins the Zero family as the third member.
Note that Zero and Zero W are currently facing supply constraints against the backdrop of a global semiconductor shortage. The foundation hopes this will be resolved in 2022.
What does the RP3A0 mark 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 the date of manufacture, expressed as year and week. Interestingly, quite a few devices were produced in the 41st week of 2020, resulting in the misleading code "2041".
The 6-digit code is the order date in the format YYMMDD.
How long will the Zero 2 W remain in production?
Maintain zero 2W production and supply until at least January 2028.
