Raspberry Pi Launches New Pi Zero 2 W Board
2021-10-28 | By Nate_Larson
The Raspberry Pi Zero 2 W is the latest product in the Zero product family. The Pi Zero line launched in November 2015 to much fanfare, presenting the world with a stripped-down, unbelievably low-cost version of the acclaimed Raspberry Pi single-board computer. Then, less than a year-and-a-half later, in February 2017, the Zero W board was released, which incorporated onboard Wi-Fi and Bluetooth while maintaining the same form-factor and processing power.
Until now, the latest product in the Zero lineup has been the Zero WH, a Raspberry Pi Zero W board with the 40-pin GPIO header pre-installed that debuted in January 2018. However, the Zero 2 W is a complete redesign rather than an incremental upgrade.
While the Zero 2 W maintains the same physical design and 65mm × 30mm footprint as the original Zero, the processor has been upgraded. Previous Pi Zero boards featured the same single-core Broadcom BCM2835 1GHz processor used for all Raspberry Pi models prior to the Raspberry Pi 2 Model B. However, the new Pi Zero 2 W features a quad-core Broadcom BCM2710A1 64-bit Arm Cortex-A53 running at 1GHz, providing computational performance closer to the Raspberry Pi 3 Model B.
The board also now sports a Raspberry Pi RP3A0 branded SiP to house the Broadcom die along with 512MB of LPDDR2 SDRAM, which is wire-bond stacked, a change resulting from a larger chip that would no longer accommodate the PoP DRAM design of previous Zero boards. The Pi Zero 2 W maintains standard Pi Zero W connectivity, including an unpopulated footprint for a HAT-compatible 40-pin GPIO header, micro USB connectors for power and an OTG compatible interface, mini HDMI port, microSD card slot, a CSI-2 camera connector, 2.4GHz 802.11 b/g/n wireless LAN, and Bluetooth 4.2 with BLE support. It should be noted that because of the redesign of the board, several of the test pads on the underside of the board have been relocated. So, the Zero 2 W may not be compatible with previously designed accessories that made use of these pads as connection points.
Compared to the original Pi Zero products, the Zero 2 W has 40% faster single-thread performance, 5.2x faster quad CPU performance vs. the previous single CPU, and a 3x faster GUI boot time. Also, contrary to previous Pi Zero products, the Raspberry Pi Zero 2 W is not limited to a single unit per customer order (subject to inventory availability.)
