Holybro pix32 Flight Controller (Discontinued)

Discontinued

PX4 does not manufacture this (or any) autopilot. Contact the manufacturer for hardware support or compliance issues.

The Holybro^® pix32 autopilot (also known as "Pixhawk 2", and formerly as HKPilot32) is based on the Pixhawk^®-project FMUv2 open hardware design. This board is based on hardware version Pixhawk 2.4.6. It runs the PX4 flight stack on the NuttX OS.

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

TIP

The Holybro pix32 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.

This flight controller is manufacturer supported.
