The Cube (Pixhawk 2.1)

The Cube is the heart of any pixhawk 2 based autopilot. Designed as a modular component the cube can fit onto a number of different carrier boards depending on the application. The Cube is the worlds most advanced autopilot for open autonomous unmanned vehicles. Redundant, temperature controlled, and vibration isolated. It runs either the PX4 or Ardupilot firmware stack giving you the ultimate flexibility with your drone.

The Cube will not function without a carrier board. This product listing is for the cube module on its own and does not include a carrier board.
