Holybro Pixhawk RPi CM4 UAV Flight Controller Baseboard

The Holybro Pixhawk RPi CM4 Baseboard makes the connection between Pixhawk Flight controllers and Raspberry Pi Compute Module 4 (RPi CM4) as a companion computer, an easy job. It creates a compact form with all the connections that one may need for development. All Pixhawk connectors and autopilot bus standard is followed for compatibility, which allows using any compatible Pixhawk Flight Controller. The flight Controller module is internally connected to the RPi CM4 through TELEM2, while there is the possibility of an ethernet connection using an external cable. Pixhawk 5X and Pixhawk 6X flight controllers are compatible with this baseboard.

Holybro’s Pixhawk 6X UAV Flight Controller is an autopilot device based on FMUv6 that is ideal for use by engineers at startups, corporate research labs, and academics (research, professors, students) as well as for commercial applications. The FMUv6X open-hardware standard includes high-performance and low-noise IMUs on board that helps improve stabilization.

Pixhawk 6X was one of the first Pixhawk boards to add support for fast Ethernet connection. With Microchip Ethernet PHY integrated into the External Sensor Bus (SPI5), high-speed communication with mission computers such as BeagleBone Black and Raspberry Pi 4 via Ethernet was made possible, as well as two chip select lines and data-ready signals for additional sensors and payload. Pixhawk 6X Autopilot firmware could handle more complex algorithms and models, thanks to the increased processing power and RAM in this flight controller.
