Rock3/CM
Radxa Compute Module 3 Series
Radxa Computing Module 3 Series (Radxa CM3 Series) is a series System-on-Module based on the Rockchip RK356x series, containing processor, memory, eMMC Flash and Power Management Unit. These modules allow a designer to leverage the ROCK3 hardware and software stack in their own custom systems and form factors. In addition these modules have extra IO interfaces over and above what is available on the ROCK3 boards, opening up more options for the designer. CM3 series compute modules comes in the following form factors:
- CM3: Compatible with Raspberry Pi CM4 in pinout and form factor
- CM3S: Compatible with Raspberry Pi CM3/CM3+, SODIMM form factor
- CM3I: Compatible with Raspberry Pi CM4 pinout in a larger size with industrial temperature range option
