We all knew Raspberry Pi Compute Module 3 were about to be launched soon, as the Raspberry Pi foundation announced a partnership with NEC displays last October, and the datasheet for two version of the Broadcom BCM2837 based system-on-module, CM3 and CM3L (Light), was released shortly after.
The good news is that the modules have officially been launched for $25 and $30 for respectively Compute Module 3 with 4GB flash, and Compute Module 3 Light with a micro SD slot. The foundation has also lowered the original compute module price to $25.
The module is mostly electrically & mechanically backward compatible with the original Compute Module, and benefits from the software running on Raspberry Pi 3 board. You’ll find specific documentation here.
In order to get started quickly, a Raspberry Pi Compute Module 3 devkit is also offered with a CM3 module and a “Compute Module IO V3” baseboard exposing GPIO headers, an HDMI port, a USB port, a micro SD slot, and more.
