Luckfox Lyra RK3506G2 Dev Board

The Luckfox Lyra (B Version) is a compact and cost-effective Linux micro development board built around the Rockchip RK3506G2 processor. Designed for embedded and IoT applications, it features a triple-core Arm Cortex-A7 CPU (1.2 GHz) and a Cortex-M0 core for real-time control, providing a balanced mix of performance and power efficiency.



With 128 MB of embedded DDR3L RAM and 256 MB SLC NAND flash, the Lyra B delivers fast and reliable operation with support for additional storage via a microSD card slot. It includes a 2-lane MIPI DSI display interface supporting resolutions up to 1280 × 800 @ 60 fps, making it ideal for smart displays, human-machine interfaces, and compact industrial devices.

The board also provides dual 20-pin GPIO headers (24 GPIO pins), a USB Type-C port for power and flashing, and a 4-pin USB connector for standard USB-A peripherals. It supports both Buildroot and Ubuntu 22.04 operating systems, giving developers flexibility in software choice. Measuring just 51 × 21 mm, the Luckfox Lyra B Version offers strong performance and rich I/O in an ultra-small form factor.
