Holybro Kakute H7

PX4 v1.13

WARNING

PX4 does not manufacture this (or any) autopilot. Contact the manufacturer for hardware support or compliance issues.

The Holybro 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, 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.

INFO

This flight controller is manufacturer supported.

PX4 Bootloader Update

The board comes pre-installed with Betaflight. Before PX4 firmware can be installed, the PX4 bootloader must be flashed. Download the kakuteh7_bl.hex bootloader binary and read this page for flashing instructions.

펌웨어 빌드

To build PX4 for this target:

make holybro_kakuteh7_default

펌웨어 설치

펌웨어는 일반적인 방법으로 설치할 수 있습니다.

• 소스 빌드 및 업로드

  make holybro_kakuteh7_default upload

• Load the firmware 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, the following parameters are important:

매개변수	설정
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.
