Radxa Zero 1GB SBC – Powerful Quad-Core Alternative to Raspberry Pi Zero W

The Radxa Zero is an ultra-compact Single Board Computer (SBC) that adopts the same form factor as the popular Raspberry Pi Zero W (65 x 30 mm). However, it stands out with significantly higher computing power thanks to its Amlogic S905Y2 quad-core Cortex-A53 processor clocked up to 1.8 GHz. This architecture delivers performance close to a standard Raspberry Pi 4 while maintaining a minimal footprint ideal for embedded projects.

This 1GB model is equipped with LPDDR4 memory and an Ampak AP6212 wireless module integrating Wi-Fi 4 (802.11b/g/n) and Bluetooth 5.0. It features a micro HDMI port for 4K video output, a CSI camera connector, and a 40-pin Raspberry Pi-compatible GPIO header for functionality expansion. Storage is handled via MicroSD card or eMMC (depending on the variant).
