Luckfox Lyra Zero W is a compact single board computer (SBC) powered by a Rockchip RK3506B triple-core Cortex-A7 SoC and mostly designed for smart wireless HMI with a MIPI DSI connector and a WiFi 6 and Bluetooth 5.2 module.
The Raspberry Pi Zero-sized board also features 512MB of RAM and a 256MB SPI flash, a microSD card slot, two USB-C ports, a USB 2.0 connector, and a 40-pin GPIO header for compatibility with (most/some) Raspberry Pi HATs.

We’re told the board supports Linux, but not much else, as the wiki (https://wiki.luckfox.com/Luckfox-Lyra-Zero-W) is not working right now… Having said that, we’ve written about other Rockchip RK3506 boards such as the Luckfox Lyra / Lyra Plus SBCs, Banana Pi BPI-Forge1, or Forlinx OK3506J-S carrier board, and Ubuntu images with a Linux 6.1 BSP based on buildroot are typically provided. The Cortex-M0 core runs RT-Thread OS.
There are multiple variants of the RK3506 SoC, and we’ve covered three so far. The RK3506G2 with on-chip 128MB DDR3L RAM, the RK3506B with external DDR3L memory as used by the Lyra Zero W SBC, and the RK3506J with external DDR3L memory and an industrial-grade temperature range.
The Luckfox Lyra Zero W is sold on AliExpress for $17.38, on Amazon for $25.99 including US shipping, and you’ll also find it for $16.99 on the Waveshare shop.
