CM4-IO-BASE-B base board dedicated to Raspberry Pi CM4 modules in a set with a USB HDMI adapter to FCC.
CM4-IO-BASE-B 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 real-time clock (RTC) chip, a backup battery socket as well as a fan connector and 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 a USB 2.0 and HDMI interface. Full documentation is available on the product Wiki page.


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.
