The Pixhawk RPI CM4 Baseboard is a controller board designed to interface with the Pixhawk flight controller and the Raspberry Pi single-board computer. It allows users to connect the Pixhawk flight controller to the Raspberry Pi, enabling the use of the Raspberry Pi as a companion computer on a drone or other unmanned vehicle. The baseboard includes connectors for the Pixhawk and Raspberry Pi, as well as a power management system that can power both devices from a single power source. It is manufactured by Holybro, a company that specializes in producing high-quality flight control and other electronics for unmanned systems.

Pixhawk 5X and 6X are reliable and powerful flight controllers which can be used to control a wide variety of vehicle systems such as drones, rovers, and submersibles. The Pixhawk is based on the PX4 open-source flight stack, which is developed by the PX4 project and designed to run on a variety of hardware platforms. The Pixhawk is widely used in the DIY drone community, as well as in commercial and research applications. It is known for its reliability, flexibility, and performance.
