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.
