|
|
|
|
<Badge type="info" text="Discontinued" />
|
|
|
|
:::warning
|
|
PX4 does not manufacture this (or any) autopilot.
|
|
Contact the [manufacturer](https://holybro.com/) for hardware support or compliance issues.
|
|
:::
|
|
|
|
The Holybro<sup>®</sup> [pix32 autopilot](https://holybro.com/products/pix32pixhawk-flight-controller) (also known as "Pixhawk 2", and formerly as HKPilot32) is based on the [Pixhawk<sup>®</sup>-project](https://pixhawk.org/) **FMUv2** open hardware design.
|
|
This board is based on hardware version Pixhawk 2.4.6.
|
|
It runs the PX4 flight stack on the [NuttX](https://nuttx.apache.org/) OS.
|
|
|
|
|
|
|
|
As a CC-BY-SA 3.0 licensed Open Hardware design, schematics and design files should be [available here](https://github.com/pixhawk/Hardware).
|
|
|
|
:::tip
|
|
The Holybro pix32 is software compatible with the [3DR Pixhawk 1](../flight_controller/pixhawk.md).
|
|
It is not connector compatible, but is otherwise physically very similar to the 3DR Pixhawk or mRo Pixhawk.
|

|
|
|
|
:::info
|
|
This flight controller is [manufacturer supported](../flight_controller/autopilot_manufacturer_supported.md).

## 펌웨어 빌드
|
|
|
|
:::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-v2_default
|
|
```
