Holybro pix32 Flight Controller (Discontinued)
:::warning 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. :::
:::info This flight controller is manufacturer supported. :::
