# Holybro Kakute H7
|
|
|
|
<Badge type="tip" text="PX4 v1.13" />
|
|
|
|
:::warning
|
|
PX4 does not manufacture this (or any) autopilot.
|
|
Contact the [manufacturer](https://holybro.com/) for hardware support or compliance issues.
|
|
:::
|
|
|
|
The [Holybro Kakute H7](https://holybro.com/products/kakute-h7) is full of features including dual plug-and-play 4in1 ESC ports, HD camera plug, barometer, OSD, 6x UARTs, full Blackbox MicroSD card slot, 5V and 9V BEC, easy soldering layout, and much more.
|
|
|
|
The Kakute H7 builds upon the best features of its predecessor, the [Kakute F7](../flight_controller/kakutef7.md), and further improves on hardware components and layout.
|
|
Dual plug'n'play 4-in-1 ESC connectors simplify support for x8 and Octocopter configurations, keeping assembly simple and clean.
|
|
|
|
The board also has an on-board barometer, LED & buzzer pad, and I2C pad (SDA & SCL) for external GPS/Magnetometers.
|
|
|
|
|
|
|
|

## PX4 Bootloader Update {#bootloader}
|
|
|
|
The board comes pre-installed with [Betaflight](https://github.com/betaflight/betaflight/wiki).
|
|
Before PX4 firmware can be installed, the _PX4 bootloader_ must be flashed.
|
|
Download the [kakuteh7_bl.hex](https://github.com/PX4/PX4-Autopilot/raw/main/docs/assets/flight_controller/kakuteh7/holybro_kakuteh7_bootloader.hex) bootloader binary and read [this page](../advanced_config/bootloader_update_from_betaflight.md) for flashing instructions.
|
|
|
|
## 펌웨어 빌드
|
|
|
|
To [build PX4](../dev_setup/building_px4.md) for this target:
|
|
|
|
```sh
|
|
make holybro_kakuteh7_default
|
|
```
|
|
|
|
## 펌웨어 설치
|
|
|
|
펌웨어는 일반적인 방법으로 설치할 수 있습니다.
|
|
|
|
- 소스 빌드 및 업로드
|
|
|
|
```sh
|
|
make holybro_kakuteh7_default upload
|
|
```
|
|
|
|
- [Load the firmware](../config/firmware.md) using _QGroundControl_.
|
|
미리 빌드된 펌웨어나 사용자 지정 펌웨어를 사용할 수 있습니다.
|
|
|
|
:::info
|
|
If you are loading the pre-built firmware via QGroundControl, you must use QGC Daily or QGC version newer than 4.1.7.
|
|

|
|
|
|
## PX4 설정
|
|
|
|
In addition to the [basic configuration](../config/index.md), the following parameters are important:
|
|
|
|
| 매개변수 | 설정 |
|
|
| -------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------ |
|
|
| [SYS_HAS_MAG](../advanced_config/parameter_reference.md#SYS_HAS_MAG) | 보드에 내부 자력계가 없기 때문에 비활성화하여야 합니다. 외부 자력계를 연결하여 활성화 할 수 있습니다. |
|
|
|
|
## 시리얼 포트 매핑
|
|
|
|
| UART | 장치 | 포트 |
|
|
| ------ | ---------- | ----------------------------------- |
|
|
| USART1 | /dev/ttyS0 | TELEM1 |
|
|
| USART2 | /dev/ttyS1 | TELEM2 |
|
|
| USART3 | /dev/ttyS2 | 디버그 콘솔 |
|
|
| UART4 | /dev/ttyS3 | GPS1 |
|
|
| USART6 | /dev/ttyS4 | RC SBUS |
|
|
| UART7 | /dev/ttyS5 | ESC 텔레메트리(DShot) |
|
|
|
|
### Using TELEM2 (USART2)
|
|
|
|
The `TELEM2` port (USART2) has no exposed solder pads as it is intended for use with Bluetooth telemetry (this does not work with PX4).
|
|
|
|
You can expose the solder pads and use the port by removing the two resistors marked with an X.
|
|
No other configuration should be required.

|
## 디버그 포트
|
|
|
|
### 시스템 콘솔
|
|
|
|
UART3 RX and TX are configured for use as the [System Console](../debug/system_console.md).
|
|
|
|
### SWD
|
|
|
|
The [SWD interface](../debug/swd_debug.md) (JTAG) pins are:
|
|
|
|
- `SWCLK`: Test Point 2 (Pin 72 on the CPU)
|
|
- `SWDIO`: Test Point 3 (Pin 76 on CPU)
|
|
- `GND`: As marked on board
|
|
- `VDD_3V3`: As marked on board
|
|
|
|
These are shown below.
