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. :::

Building Firmware

:::tip Most users will not need to build this firmware! It is pre-built and automatically installed by QGroundControl when appropriate hardware is connected. :::

To build PX4 for this target:

make px4_fmu-v2_default

Debug Port

See 3DR Pixhawk 1 > Debug Ports.

Pinouts and Schematics

The board is based on the Pixhawk project FMUv2 open hardware design.
