Pixhawk 3 Pro (Discontinued)
:::warning PX4 does not manufacture this (or any) autopilot. Contact the manufacturer for hardware support or compliance issues. :::
The Pixhawk® 3 Pro is based on the FMUv4 hardware design (Pixracer) with some upgrades and additional features. The board was designed by Drotek® and PX4.
::: info The main hardware documentation is here: https://drotek.gitbook.io/pixhawk-3-pro/hardware :::
:::tip This autopilot is supported by the PX4 maintenance and test teams. :::

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-v4pro_default
Debug Port
The board has FMU and IO debug ports as shown below.
The pinouts and connector comply with the Pixhawk Debug Mini interface defined in the Pixhawk Connector Standard (JST SM06B connector).
| Pin | Signal | Volt |
|---|---|---|
| 1 (red) | VCC TARGET SHIFT | +3.3V |
| 2 (blk) | CONSOLE TX (OUT) | +3.3V |
| 3 (blk) | CONSOLE RX (IN) | +3.3V |
| 4 (blk) | SWDIO | +3.3V |
| 5 (blk) | SWCLK | +3.3V |
| 6 (blk) | GND | GND |
For information about wiring and using this port see:
- SWD Debug Port
- PX4 System Console (Note, the FMU console maps to UART7).
