Pixhack V3

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

The CUAV Pixhack V3 flight controller board is a flexible autopilot intended primarily for manufacturers of commercial systems.

The board is a variant of the SOLO Pixhawk^® 2 (PH2) flight controller, which is in turn based on the Pixhawk-project FMUv3 open hardware design. It runs PX4 on the NuttX OS, and is fully compatible with both PX4 or ArduPilot^® (APM) firmware.

Pixhack V3 has significant improvements with respect to the original design, including better interface layout and the addition of vibration damping and a thermostat system.
