Product Introduction
Key Features
- CM3 Core Board
- CM3 IO Board
Radxa CM3 is a system-on-module (SoM) based on the Rockchip RK3566 system-on-chip (SoC). CM3 integrates a central processing unit (CPU), power management unit (PMU), DRAM memory, flash storage, and wireless connectivity (WiFi 5 and BT 5.0). It features a compact form factor measuring just 55mm x 40mm. Radxa CM3 Core Board uses 3x 100P 0.4mm pitch B2B connectors, providing robust functionality support to integrate with customers' baseboards for accelerated product development processes.
We offer Radxa CM3 IO Board, compatible with Radxa CM3, allowing you to develop the products you envision, such as HMI, robots, intercoms, smart homes, and more.
