HKPilot32 Flight Controller

The Hobbyking HKPilot32 autopilot is based on the Pixhawk-project FMUv2 open hardware design. It runs the PX4 Flight Stack on the NuttX OS.

The HKPilot32 is software compatible with the 3DR Pixhawk 1. It is not connector compatible, but is otherwise physically very similar to the 3DR Pixhawk or mRo Pixhawk.

As a CC-BY-SA 3.0 licensed Open Hardware design, schematics and design files should be available here.
