Raspberry Pi Compute Module 3

The 68.7 x 31mm Compute Module 3 (CM3) integrates the guts of a Raspberry Pi 3 (1.2GHz-clocked quad-core BCM2837 SoC + 1GB RAM), plus 4GB eMMC storage. The module plugs into a standard DDR2 SODIMM connector and all additional processor interfaces are available via the edge-connector (many more GPIOs and I/Os than on a standard RPi SBC). The CM3L (“Lite”) omits the eMMC flash.
