Introduction

Radxa Zero SBC follows Raspberry Pi Zero W form factor, but thanks to an Amlogic S905Y2 quad-core Cortex-A53 processor clocked at up to 2.0 GHz offers much higher performance, which Radxa says corresponds to about 70% of Raspberry Pi 4 CPU performance.

The tiny Arm Linux board comes with up to 4GB RAM, 16GB eMMC flash, and either AP6212 or AP6256 wireless module. plus all interfaces from Raspberry Pi Zero W, but with a twist as the mini HDMI port is replaced by a micro HDMI port, and USB-C ports are used instead of micro USB ports.

specifications:

SoC – Amlogic S905Y2 quad-core Cortex-A53 processor @ up to 2.0 GHz with Arm Mali-G31 MP2 GPU
System Memory – 2G Ram 8G Emmc
Video Output – micro HDMI port up to 4Kp60

Connectivity
-Ampak AP6212 module – 802.11b/g/n WiFI 4 up to 72 Mbps plus Bluetooth 4.0 or
-Ampak AP6256 module – 802.11n/g/n/ac WiFi 5 up to 433 Mbps and Bluetooth 5.0

USB – 1x USB-C 2.0 OTG port, 1x USB-C 3.0 host port
Camera – 1x CSI camera connector
Expansion – Color-coded 40-pin Raspberry Pi compatible header
Power Supply – 5V via USB-C port
Dimensions – 65 x 30 x 5mm (same as Raspberry Pi Zero W)

The only missing feature is the MIPI CSI camera, but for everything else, Radxa Zero offers much better specifications depending on the selected memory, storage, and wireless module compared to Raspberry Pi Zero W.

The board should run Android and works is being done on Armbian/Twister OS, and other operating systems. From a software perspective, it’s a “G12A” platform, a reference you’ll find in the Linux kernel for example, and compatible with Amlogic S905X2.
