# Pixhack v3

注意

PX4 does not manufacture this (or any) autopilot. Contact the manufacturer (opens new window) 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 (opens new window) FMUv3 open hardware design. It runs PX4 on the NuttX (opens new window) 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.
