_Pix32 v6_<sup>®</sup> is the latest update to the pix32 v5 flight controllers. It is a variant of the Pixhawk 6C with a modular design and shares the same FMUv6C Target. It is comprised of a separate flight controller and carrier board which are connected by a [100 pin connector](https://docs.holybro.com/autopilot/pix32-v6/download). It is designed for those pilots who need a high power, flexible and customizable flight control system.
|
||
|
||
It is equipped with a high performance H7 Processor, and comes with IMU redundancy, temperature-controlled IMU board, and cost effective design, delivering incredible performance and reliability. It complies with the [Connector Standard](https://github.com/pixhawk/Pixhawk-Standards/blob/master/DS-009%20Pixhawk%20Connector%20Standard.pdf).

|
||
## Introduction
|
||
|
||
Inside the Pix32 v6, you can find an STMicroelectronics® based STM32H743, paired with sensor technology from Bosch® & InvenSense®, giving you flexibility and reliability for controlling any autonomous vehicle, suitable for both academic and commercial applications.
|
||
|
||
The Pix32 v6’s H7 MCU contain the Arm® Cortex®-M7 core running up to 480 MHz, has 2MB flash memory and 1MB RAM. Thanks to the updated processing power, developers can be more productive and efficient with their development work, allowing for complex algorithms and models. It includes high-performance, low-noise IMUs on board, designed to be cost effective while having IMU redundancy. A vibration isolation System to filter out high-frequency vibration and reduce noise to ensure accurate readings, allowing vehicles to reach better overall flight performances.
|
||
|
||
This flight controller is perfect for people that is looking for a affordable and modular flight controller that can use a customized baseboard. We have made the [pix32 v6 base board schematics public](https://docs.holybro.com/autopilot/pix32-v6/download), you can either make a custom carrier board yourself or just let us help you with it. By using a customize baseboard, you can make sure that the physical size, pinouts and power distribution requirements match your vehicle perfectly, ensuring that you have all the connections you need and none of the expense and bulk of connectors you don’t.

|
||
## Voltage Ratings
|
||
|
||
_Pix32 v6_ can be triple-redundant on the power supply if three power sources are supplied. The three power rails are: **USB**, **POWER1**, **POWER2** (N/A on Pix32 v6 Mini-Baseboard) .
|
||
|
||
**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)
|
||
|
||
**Voltage monitoring**
|
||
|
||
Pix32 v6 uses analog power modules.
|
||
|
||
Holybro makes various analog [power modules](../power_module/index.md) for different need.

## 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 px4_fmu-v6c_default
|
||
```
|
||
|
||
## Debug Port {#debug_port}
|
||
|
||
The [PX4 System Console](../debug/system_console.md) and [SWD interface](../debug/swd_debug.md) run on the **FMU Debug** port.
|
||
|
||
The pinouts and connector comply with the [Pixhawk Debug Full](../debug/swd_debug.md#pixhawk-debug-full) interface defined in the [Pixhawk Connector Standard](https://github.com/pixhawk/Pixhawk-Standards/blob/master/DS-009%20Pixhawk%20Connector%20Standard.pdf) interface (JST SM10B connector).
|
||
|
||
| Pin | Signal | Volt |
|
||
| -------- | ---------------- | ----- |
|
||
| 1 (red) | `Vtref` | +3.3V |
|
||
| 2 (blk) | Console TX (OUT) | +3.3V |
|
||
