The board is compatible with all Raspberry Pi CM4 modules equipped with eMMC. Depending on your needs, you can select a CM4 module with an SDRAM of 1GB, 2GB, 4GB, or 8GB and the eMMC of 8GB, 16GB, or 32G, with or without the Wi-Fi / BT4 connection.

The Ochin board has also been tested to work with OpenHD open source software. Thanks to OpenHD it is possible to transmit an HD video stream with low latency from a mobile station (rover, drone, plane, etc ..) to a ground station. This was possible thanks to the enormous work of the OpenHd community which we thank very much.

There are rich interfaces available on board including 1×USB 2.0 port (highspeed), MIPI CSI-2: 1×2-lane MIPI CSI camera port, 1×4-lane MIPI CSI camera port,1×USART, 3×UART, 1×I2C port, 1×SPI port, and Analog Video Output, all of which enable the Ochin CM4 to connect to external hardware at lower abstraction layers, closer to the physical world.

In terms of external dimensions, it’s the same as the CM4 module which adopts a completely new mechanical standard. The overall footprint is reduced, resulting in a smaller and more compact form factor suitable for integration into products.
