Overview

The Radxa ROCK 3 Compute Module (CM3) is a System on Module (SoM) based on a the Rockchip RK3566 System on Chip (SoC). The CM3 integrates the Central Process Unit (CPU), Power Management Unit (PMU), DRAM memory, flash storage and wireless connectivity (WiFi 5 and BT 5.0) in a small form factor of just 55mm x 40mm. The ROCK CM3 core board uses 3x 100P 0.4mm pitch B2B connector to provide powerful functional support, and can be combined with the customer's backplane to build complete product functions, thereby speeding up the research and development process.

ROCK CM3

The ROCK CM3 is available in various LPDDR4 RAM and eMMC size configurations:

  • RAM: 1 / 2 / 4 / 8 GB
  • eMMC: NA / 8 / 16 / 32 GB

At the same time, we provide ROCK CM3 IO Board compatible with ROCK CM3, you can use it to develop the products you want. For example, HMI, robot, video intercom, smart home, etc.
