Product Introduction

Key Features

Radxa CM3I is a system-on-module (SoM) based on the Rockchip RK3568(J) system-on-chip (SoC). Radxa CM3I integrates a central processing unit (CPU), power management unit (PMU), DRAM memory, flash storage, and wireless connectivity (WiFi 5 and BT 5.0). With a compact form factor of just 70mm x 40mm, Radxa CM3I offers a cost-effective solution for a wide range of applications.

Powerful Multimedia Processing Capabilities

The CPU adopts the advanced ARM Cortex-A55 architecture, integrating a powerful GPU that supports high-definition video decoding and encoding, capable of handling various video formats and resolutions. Additionally, the RK3568J is equipped with a high-performance DSP and NPU (Neural Processing Unit) for audio processing and artificial intelligence applications, making it outstanding in multimedia processing.

Potential for Development

As a powerful development platform, the Radxa CM3I has significant potential in fields such as artificial intelligence, edge computing, and embedded systems.
