Loading 3D model… large boards can take a moment.
Production build of a compact carrier board for the Raspberry Pi Compute Module 4 and Compute Module 5. The board combines USB-C data and power, Ethernet, 25 W PoE input, M.2 storage and essential peripheral connections in a 120 mm × 40 mm form factor.
The carrier board can be powered through either USB-C or PoE. The active input is selected using the onboard power-selection jumper.
The USB-C input provides 5 V at up to 3 A and uses CC pull-down resistors for source detection. The PoE interface operates as a 25 W powered device through the Ethernet connection.
The M.2 M-Key interface supports 2230, 2242 and 2260 module sizes. A microSD card socket is provided for CM4 Lite and CM5 Lite variants without onboard eMMC storage.
UART, I²C and PWM fan connections are exposed through dedicated 3-pin JST connectors. PWR and ACT LEDs provide visible system-status indication.
