From the project
Open-source six-layer Raspberry Pi CM4/CM5 carrier board with USB-C, 25 W PoE, M.2 NVMe, microSD, I2S, and expansion-board connectors.
A compact six-layer carrier board for the Raspberry Pi Compute Module 4, Compute Module 5 and compatible modules. Rev2 retains the 120 mm × 40 mm form factor while improving CM4 compatibility and adding an I²S connector and two underside expansion-board interfaces.
- M.2 interface revised to support CM4, CM5 and compatible compute modules - PWM fan control revised to operate correctly with CM4 and compatible modules - I²S JST connector added to the main board - Two 50-pin Hirose connectors added on the underside for a companion expansion board
