Product Introduction

Key Features​

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.

Powerful Multimedia Processing Capability​

The CPU adopts a quad-core A55 (ARM v8) architecture running at 1.8 GHz, providing robust computing power and multitasking capabilities. The GPU integrates Mali G52-2EE, supporting Arm Mali™-G52-2EE, OpenGL® ES1.1/2.0/3.0/3.1/3.2, Vulkan® 1.1, OpenCL™ 2.1, ensuring efficient and smooth graphics processing.

Potential for Development​

As a powerful development platform, Radxa CM3 holds great potential in artificial intelligence, edge computing, embedded systems, and more.

Strong Compatibility​

It is compatible not only with Radxa CM3 IO Board but also with Raspberry Pi CM4 IO Board, Seeed Studio Dual Gigabit Ethernet Carrier Board, Waveshare CM4 IO Base, Mcuzone CM4 Mini, and Mcuzone CM4 Tiny.
