# Pixhack V3
|
|
|
|
:::warning
|
|
PX4 does not manufacture this (or any) autopilot.
|
|
Contact the [manufacturer](https://store.cuav.net/) 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<sup>®</sup> 2 (PH2) flight controller, which is in turn based on the [Pixhawk-project](https://pixhawk.org/) **FMUv3** open hardware design.
|
|
It runs PX4 on the [NuttX](https://nuttx.apache.org/) OS, and is fully compatible with both PX4 or ArduPilot<sup>®</sup> (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.
|
|
|
|
|
|
|
|
::: info
|
|
This flight controller is [manufacturer supported](../flight_controller/autopilot_manufacturer_supported.md).

## 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](../dev_setup/building_px4.md) for this target:
|
|
|
|
```
|
|
make px4_fmu-v3_default
|
|
```
|
