CM4-IO-BASE-A base board dedicated to Raspberry Pi CM4 modules in a set with a USB HDMI adapter to FCC.
CM4-IO-BASE-A is equipped with special connectors for connecting the module and the outputs of all CM4 module interfaces, including USB, Ethernet, HDMI, DSI, two CSI connectors, 40-Pin GPIO connector compatible with HAT modules. The Mini Base Board is additionally equipped with a microSD card slot. At the bottom of the board, there is also an M.2 connector for connecting additional modules or a disk, and an FFC connector with USB 2.0 and HDMI interface. Full documentation is available on the product Wiki page.


Compared to version B, the board has no RTC clock, fan controller and battery socket. The 40-pin connector is color-coded, which makes it easy to connect expansion modules. The board has compact dimensions (85 x 56 mm) corresponding to the dimensions of the Raspberry Pi 4 model B minicomputers, thanks to which, after connecting the Raspberry Pi CM4 module (not included), it can be a replacement for standard Raspberry Pi minicomputers.
Adapter with USB and HDMI connectors connected via FFC tape. It allows you to add two USB connectors and HDMI connectors for base boards.
