Pixhawk Baseboard compatible with Raspberry Pi CM4

Dec 11, 2022 — by Giorgio Mendoza 1,586 views

The Pixhawk RPI CM4 Baseboard from Holybro is a Flight Controller platform supporting an RPi CM4 and the new Pixhawk 5X & 6X. The Baseboard provides support for Pixhawk/Ardupilot protocols (i.e. GPS, Telemetry, CAN, etc.) in addition to a Mini HDMI port, a CSI connector and dedicated power ports for the FC and the RPI CM4. 

The RPi CM4 and FC can interface each other using an internal Telemetry port (TELEM2) from the baseboard or using the ethernet port located next near the CSI connector as shown below. The baseboard also includes a DIP switch to select the CM4 Host/Slave modes.

Holybro is offering the Pixhawk RPI CM4 Baseboard along with a Power Module compatible with the Pixhawk 5X & 6X. The flight controller is powered using a 6-pin CLIK-Mate cable to the “Power1” port as seen in the image below. Similarly, PM03D power module uses a 4-pin to USB-C cable (5.2V/3A) to power the RPi CM4.

The PM03D also includes 6x XT30 connectors to handle motors’ ESCs, up to 4x B+/GND solder pads for additional devices requiring power and 3-pin headers for 5V and 8V/12V devices (i.e., servo motors). For reference, the PM03D supports up to 6S batteries and it’s rated for 60A (max current 120A, <60 sec)

The installation guide, RPi CM4 Flash guide and other relevant documentation can be found on Holybro Docs website using this link. The PX4 forum also provides a short tutorial to set up the CM4 + the Pixhawk 6X to boot up.
