ROCK 3 Computing Module(ROCK CM3) is a System-on-Module based on the ROCK3, 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.
