The Compute Module is a Raspberry Pi board in a more flexible form factor, intended for industrial application. CM3 is the Raspberry Pi 3-based revision of the original Compute Module.

The Compute Module contains the guts of a Raspberry Pi 3 (the BCM2837 processor and 1GB RAM) as well as 4GB of eMMC flash storage (which is the equivalent of the SD card in the Pi). The Pi 3 has a processor speed of 1.2GHz and runs at roughly 10 times the speed of the Pi 1 due to its quad-core CPU. This is all integrated on to a small 67.6mm x 31mm board which fits into a standard DDR2 SODIMM connector (the same type of connector as used for laptop memory). The Flash memory is connected directly to the processor on the board, but the remaining processor interfaces are available to the user via the connector pins. You get the full flexibility of the BCM2837 SoC (which means that many more GPIOs and interfaces are available as compared to the Raspberry Pi), and designing the Module into a custom system should be relatively straightforward as the Raspberry Pi Foundation has put all the tricky bits onto the Module itself.

The compute module has significant differences from other Pi boards that should be noted, as configuring it requires a different process;

  1. It has 4GB of onboard eMMC memory from which to boot, and there is no ability to expand the size of boot memory. OS images are therefore limited to 4GB.
  2. In order to flash the OS onto the eMMC memory, the compute module must either be connected to the Compute Module IO Board for USB programming, or via its 200-pin SODIMM edge connector.
