The Luckfox Lyra Pi is a compact, Raspberry Pi-sized SBC built around the Luckfox Core3506 core board with a Rockchip RK3506B triple-core Cortex-A7 processor with an additional Cortex-M0 core for IoT, edge computing, and industrial control applications.
The board features 512MB DDR3L RAM, optional 8GB eMMC flash, a microSD card slot, dual 10/100Mbps Ethernet with optional PoE, MIPI DSI, USB Type-A and Type-C ports, a 3.5mm audio jack, and a 40-pin GPIO header for Raspberry Pi HATs. The SBC also supports Wi-Fi 6 and Bluetooth 5.2, includes an M.2 slot for an optional 4G LTE module, and offers RS-485 and CAN Bus industrial connectivity.

The Lyra Pi SBC comes in four different varieties, all of which feature the RK3506B. The only difference is in storage and wireless options. Model A includes 8GB eMMC with no wireless or MicroSD. Model B uses a MicroSD card for storage with no eMMC and no wireless. Model A W adds Wi-Fi 6 and Bluetooth 5.2 to the 8GB eMMC but lacks a MicroSD slot. Model B W has wireless and a MicroSD slot, but no eMMC.
In terms of software, the board supports Buildroot and Ubuntu 22.04. But at the time of writing, there is no dedicated Wiki available for the Lyra Pi, but I found general documentation for its Lyra series boards.
It’s the second Rockchip RK3506B board from LuckFox with Raspberry Pi form factor, but the LuckFox Lyra Zero W specifically followed the smaller Zero form factor, while the LyRa Pi SBC discussed here is based on Model B designs.
All four Luckfox Lyra Pi variants are available on AliExpress for $27.34 to $$78.59, depending on the selected model and options like 4G LTE and MIPI DSI display modules. Alternatively, the board can also be purchased on the Waveshare store.
