# AUAV-X2 Autopilot (Discontinued)

<Badge type="info" text="Discontinued" />

:::warning
This flight controller has been [discontinued](../flight_controller/autopilot_experimental.md) and is no longer commercially available.
:::

:::warning
PX4 does not manufacture this (or any) autopilot.
Contact the [manufacturer](https://store.mrobotics.io/) for hardware support or compliance issues.
:::

The AUAV-X2 autopilot is based on the [Pixhawk<sup>&reg;</sup>-project](https://pixhawk.org/) **FMUv2** open hardware design. It runs PX4 on the [NuttX](https://nuttx.apache.org/) OS.
