The Pixhawk® 4 Mini autopilot is designed for engineers and hobbyists who are looking to tap into the power of Pixhawk 4 but are working with smaller drones. 

Pixhawk 4 Mini takes the FMU processor and memory resources from the Pixhawk 4 while eliminating interfaces that are normally unused.

This allows the Pixhawk 4 Mini to be small enough to fit in a 250mm racer drone.

Pixhawk 4 Mini was designed and developed in collaboration with Holybro® and Auterion®.

It is based on the Pixhawk FMUv5 design standard and is optimized to run PX4 flight control software.
