With our devices and for individual sale, we offer two kinds of Raspberry Pi IO boards which serve different purposes. These two IO boards are:
The Andino CM4 board provides various connectivity options for the CM4 and adapts it to a Raspberry Pi formfactor, thus allowing usage of the Compute Module with Raspberry Pi accessories. Its unique selling point is the fact that it exposes the PCIe X1 lanes of the Compute Module. It therefore allows for an M.2 NVMe SSD to be connected. All connectivity options of the Andino CM4 IO Board are:
The SHCHV CM4 to Pi4 IO Board adapts the Compute Module 4 to exactly the same formfactor as a Raspberry Pi 4 and also provides the same connectivity options:
In contrast to the Andino CM4 IO Board, however, there is no way to connect an NVMe SSD to this board.
