The Holybro Pixhawk RPi CM4 Baseboard combines the Pixhawk FC module with the Raspberry Pi CM4 companion computer in a compact form factor with all the connections you need for your project. 

It follows the Pixhawk Connector and Autopilot Bus Standard, allowing easy swapping of the FC Module with any FC that follows the Pixhawk Bus Standard. The FC Module is internally connected to RPi CM4 through TELEM2, and can also be connected via ethernet with an external cable provided. It is compatible with the Pixhawk 5X and 6X flight controller modules.
 
Hint: This Pixhawk RPi baseboard supports Raspberry Pi CM4 and CM5. The CM5 requires more power, and the USB-C port used for flashing also powers the Pi. If your computer doesn’t provide enough power, use a powered USB hub for reliable flashing operation.
