The 3DR Pixhawk Mini autopilot is a next-generation evolution of the Pixhawk (designed by 3DR in collaboration with HobbyKing). It is about 1/3rd the size of the original Pixhawk and has more powerful processors and sensors.
The Pixhawk Mini is based on the PX4 open-hardware project and has been optimized for the PX4 flight stack.
