Ochin Raspberry Pi CM4 Carrier Board

Flavio Ansovini has launched a carrier board Ochin CM4 for the Raspberry Pi Compute Module 4. The compact carrier board is built specifically for size-constrained projects like robotics and drone automation and is available under an open license. The key feature of the Ochin CM4 is its small dimensions, taking up the same footprint as the Raspberry Pi Compute Module 4 it's designed to host.

It is compatible with all full-fat Compute Module 4 models but lacks a MicroSD slot for storage which means it won't work with the Compute Module 4 Lite range, which lacks onboard eMMC storage. The carrier breaks out a single USB 2.0 Type-C port for eMMC flashing, four USB 2.0 GHS connectors, one two-lane and one four-lane MIPI CSI camera port, three UARTs, one USART, one I2C bus, and analog video output, with networking provided by the Raspberry Pi CM4's on-board Wi-Fi and Bluetooth radios. 


  • Supported modules – Raspberry Pi CM4 with Broadcom BCM2711 quad-core Cortex-A72 processor, up to 8GB RAM, up to 32GB eMMC flash (the CM4 Lite is not supported since there’s no microSD card on the board), 4Kp60 H.265 decode, 1080p30 H.264 encode, and optional WiFI 5 and Bluetooth 5.0

  • USB – 1x USB 2.0 Type-C port

  • Camera I/F – 1x 4-lane MIPI CSI connector, 1x 2-lane MIPI CSI connector

  • Misc – Boot mode button

  • Dimensions – 55 x 40 x 4.7mm

  • 4x USB 2.0 GHS connector

  • 1x SPI GHS connector

  • 1x I2C GHS connector

  • GHS Connector with UART 0/1 (only one interface selectable), composite video out, 5V, 3.3V, and GND

  • UART 3/5 GHS connector (both interfaces)

  • USART4 GHS connector
