# Pixhawk 시리즈

[Pixhawk<sup>&reg;</sup>](https://pixhawk.org/) is an independent open-hardware project providing readily-available, low-cost, and high-end, _autopilot hardware designs_ to the academic, hobby and industrial communities.

Pixhawk is the reference hardware platform for PX4, and runs PX4 on the [NuttX](https://nuttx.apache.org/) OS.

제조업체는화물 운반에서 1인칭 시점(FPV) 레이서에 이르는 애플리케이션에 최적화 된 폼 팩터를 사용하여 개방형 디자인을 기반으로 다양한 보드를 제조하였습니다.

:::tip
For computationally intensive tasks (e.g. computer vision) you will need a separate companion computer (e.g. [Raspberry Pi 2/3 Navio2](../flight_controller/raspberry_pi_navio2.md)) or a platform with an integrated companion solution.

## 주요 장점

Key benefits of using a _Pixhawk series_ controller include:

- 소프트웨어 지원 - PX4 기준 하드웨어로서 가장 잘 관리되는 보드입니다.
- 장착 가능한 하드웨어 주변 장치의 유연성.
- 고품질
- 폼 팩터 측면에서 정밀하게 수정할 수 있습니다.
- 널리 사용되어 잘 테스트되고 안정적입니다.
- Automated update of latest firmware via _QGroundControl_ (end-user friendly).

## 지원 보드

The PX4 Project uses [Pixhawk Standard Autopilots](../flight_controller/autopilot_pixhawk_standard.md) as reference hardware.
Pixhawk 표준(상표 사용 포함)과 호환는 컨트롤러입니다.

:::info
The PX4 maintenance and test teams maintain and support these standard boards.
:::

Pixhawk-like boards that are not fully compliant with the specification may be [manufacturer-supported](../flight_controller/autopilot_manufacturer_supported.md), [experimental/discontinued](../flight_controller/autopilot_experimental.md), or unsupported.

이 섹션의 나머지 부분에서는 Pixhawk 시리즈에 대해 조금 더 설명하지만 반드시 읽어야하는 것은 아닙니다.

## 배경

The [Pixhawk project](https://pixhawk.org/) creates open hardware designs in the form of schematics, which define a set of components (CPU, sensors, etc.) and their connections/pin mappings.

Manufacturers are encouraged to take the [open designs](https://github.com/pixhawk/Hardware) and create products that are best suited to a particular market or use case (the physical layout/form factor not part of the open specification). 동일한 디자인의 보드는 바이너리 수준에서 호환이 가능합니다.

:::info
While a physical connector standard is not mandated, newer products generally follow the [Pixhawk Connector Standard](https://github.com/pixhawk/Pixhawk-Standards/blob/master/DS-009%20Pixhawk%20Connector%20Standard.pdf).
:::

The project also creates reference autopilot boards based on the open designs, and shares them under the same [licence](#licensing-and-trademarks).

### FMU 버전

Pixhawk 프로젝트는 다양한 개방형 회로도를 디자인하였습니다.
같은 디자인의 보드들은 동일한 펌웨어가 바이너리 수준에서 호환되어야 합니다.

각 디자인의 이름은 FMUvX(예 : FMUv1, FMUv2, FMUv3, FMUv4 등)입니다.
FMU 번호가 높을 수록 보드가 최신 버전이며, 반드시 성능 향상을 의미하지는 않습니다. 버전이 거의 동일할 수 있으며 커넥터 배선만 다를 수 있습니다.

PX4 _users_ generally do not need to know very much about FMU versions:

- _QGroundControl_ automatically downloads the correct firmware for a connected autopilot (based on its FMU version "under the hood").
- 일반적으로 FMU 버전이 아닌 물리적 제약과 폼 팩터에 의해서 컨트롤러를 선택합니다.

:::info
The exception is that if you're using FMUv2 firmware it is [limited to 1MB of flash](../flight_controller/silicon_errata.md#fmuv2-pixhawk-silicon-errata).
이 제한된 공간에 PX4를 맞추기 위하여, 다수의 모듈들이 비활성화되어 있습니다.
You may find that some [parameters are missing](../advanced_config/parameters.md#missing) and that some hardware does not work "out of the box".
:::

PX4 _developers_ need to know the FMU version of their board, as this is required to build custom hardware.

## 추가 정보

### LED

All _Pixhawk-series_ flight controllers support:

- A user facing RGB _UI LED_ to indicate the current _readiness to fly_ status of the vehicle. This is typically a superbright I2C peripheral, which may or may not be mounted on the board (i.e. FMUv4 does not have one on board and typically uses an LED mounted on the GPS).
- Three _Status LED_s that provide lower level power status, bootloader mode and activity, and error information.

To interpret the LEDs see: [LED Meanings](../getting_started/led_meanings.md).
