The Compute Module is a Raspberry Pi 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 1 GB RAM) as well as a 4 GB eMMC Flash device (which is the equivalent of the SD card in the RPi). The RPi 3 has a processor speed of 1.2 GHz and runs at roughly 10 times the speed of the RPi 1 due to its quad-core CPU. This is all integrated on to a small 67.6 x 31 mm 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 we’ve put all the tricky bits onto the Module itself.
