Just the thing for a drone nerds man cave, sorry hanger.

The Cube autopilot is a further evolution of the Pixhawk autopilot. It is designed for commercial systems and manufacturers who wish to fully integrate a autopilot into their system. On top of the existing features of Pixhawk, it has the following enhancements:

  • 3 sets of IMU sensors for extra redundancy
  • 2 sets of IMU are vibration-isolated mechanically, reducing the effect of frame vibration to state estimation
  • IMUs are temperature-controlled by onboard heating resistors, allowing optimum working temperature of IMUs
  • The entire flight management unit(FMU) and inertial management unit(IMU) are housed in a reatively small form factor (a cube). All inputs and outputs go through a 80-pin DF17 connector, allowing a plug-in solution for manufacturers of commercial systems. Manufacturers can design their own carrier boards to suite their specific needs.
