# Holybro Pix32 v5

::: warning
PX4 does not manufacture this (or any) autopilot.

:::

[Pix32 v5](https://holybro.com/products/pix32-v5)<sup>&reg;</sup> is an advanced autopilot flight controller designed and made by Holybro<sup>&reg;</sup>.
It is optimized to run on PX4 firmware, which is intended for both academic and commercial developers.
It is based on the [Pixhawk-project](https://pixhawk.org/) **FMUv5** open hardware design and runs PX4 on the [NuttX](https://nuttx.apache.org/) OS.
It can be regarded as a variant version of Pixhawk4.

The Pix32 v5 is designed for pilots who need a high power, flexible and customisable flight control system.
It is comprised of a separate flight controller and carrier (base) board, which are connected by a 100pin connector.
This design allows users to either select a base board made by Holybro, or customize their own.

## Voltage Ratings

_Pix32 v5_ can be triple-redundant on the power supply if three power sources are supplied.
The three power rails are: **POWER1**, **POWER2** and **USB**.

::: info
The output power rails **FMU PWM OUT** and **I/O PWM OUT** (0V to 36V) do not power the flight controller board (and are not powered by it).
You must supply power to one of **POWER1**, **POWER2** or **USB** or the board will be unpowered.
:::

**Normal Operation Maximum Ratings**

Under these conditions all power sources will be used in this order to power the system:

1. **POWER1** and **POWER2** inputs (4.9V to 5.5V)
1. **USB** input (4.75V to 5.25V)

**Absolute Maximum Ratings**

Under these conditions the system will not draw any power (will not be operational), but will remain intact.

1. **POWER1** and **POWER2** inputs (operational range 4.1V to 5.7V, 0V to 10V undamaged)
1. **USB** input (operational range 4.1V to 5.7V, 0V to 6V undamaged)
1. Servo input: VDD_SERVO pin of **FMU PWM OUT** and **I/O PWM OUT** (0V to 42V undamaged)

## 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:

```sh
make holybro_pix32v5_default
```

## Debug Port

The system's [serial console](../debug/system_console.md) and SWD interface runs on the **FMU Debug** port

<!--while the I/O console and SWD interface can be accessed via **I/O Debug** port.-->

![FMU debug port diagram](../../assets/flight_controller/holybro_pix32_v5/FMU_Debug_Port_Horizontal.jpg)

The pinout uses the standard [Pixhawk Debug Mini](../debug/swd_debug.md#pixhawk-debug-mini) interface defined in the [Pixhawk Connector Standard](https://github.com/pixhawk/Pixhawk-Standards/blob/master/DS-009%20Pixhawk%20Connector%20Standard.pdf).

## Peripherals

- [Digital Airspeed Sensor](../sensor/airspeed.md)
- [Telemetry Radio Modules](../telemetry/index.md)
- [Rangefinders/Distance sensors](../sensor/rangefinders.md)

## Supported Platforms / Airframes

Any multicopter / airplane / rover or boat that can be controlled with normal RC servos or Futaba S-Bus servos.
The complete set of supported configurations can be seen in the [Airframes Reference](../airframes/airframe_reference.md).
