Technical Highlights

Designed for Fixed-Wing and VTOL Builds

The Kakute H743-Wing combines an STM32H743 flight controller with a dedicated power board. Fourteen PWM outputs, CAN connectivity and external GPS support provide the interfaces needed for fixed-wing and VTOL integration.

H743 Processing and Onboard Sensors

The STM32H743VIT6 MCU runs at 480 MHz. The pictured configuration uses an SPI-connected ICM-42688P IMU, a BMP280 barometer and an AT7456E analog OSD chip.

3–8S Power System

The power board accepts 10–36 V from a 3–8S LiPo battery. It provides regulated 5 V, selectable 6 V/8 V servo power and selectable 9 V/12 V accessory power. Selectable voltages require the corresponding jumper configuration.

Camera and Peripheral Integration

Dual analog camera inputs can be switched through the flight controller. Dedicated GPS, CAN and I2C connectors, seven UARTs and a microSD slot support navigation peripherals, telemetry and flight logging.

Integration Notes

Choose the GPS option explicitly; a GPS module is not built into the flight controller.
Use the documented 10–36 V battery input range. Do not use the “2S–8S” notation shown in one supplied wiring image as the electrical rating.
Confirm the barometer fitted to the supplied batch, because Holybro lists BMP280 and SPA06 versions.
Set the servo and accessory-power jumpers for the required output voltages before connecting peripherals.
Use the firmware target corresponding to the selected INAV or ArduPilot installation.

FAQ

Is GPS built into the Kakute H743-Wing?

No. The flight controller has a dedicated GPS port. The supplied images show separate package options with no GPS, a Micro M9N GPS or a Micro M10 GPS.

What battery voltage does the power board support?

Holybro specifies a 10–36 V input range for 3–8S LiPo batteries.

Which firmware targets should be selected?

Use KAKUTEH7Wing for supported INAV releases or KakuteH7-Wing for supported ArduPilot releases. Holybro lists INAV 6.1.1 or newer and ArduPilot 4.4 or newer.

How many PWM outputs are available?

The flight controller provides 14 PWM outputs for the aircraft configuration.

Does the flight controller contain an ESC or video transmitter?

No integrated ESC or VTX is specified. The board provides ESC power pads, control outputs, camera inputs and regulated accessory power for connecting external equipment.

B2B Procurement FAQ

How should the GPS option be stated in an inquiry?

Specify “Kakute H743-Wing only,” “with Micro M9N GPS,” or “with Micro M10 GPS.” Confirm the exact package contents and part numbers in the quotation.

Can the fitted barometer be confirmed before ordering?

Yes, request confirmation of the actual batch configuration. The supplied diagram shows BMP280, while Holybro also lists SPA06 as a possible barometer version.

Are pre-soldered pin headers included?

The supplied package images show separate pin headers. If pre-soldered headers are required, specify that configuration in the inquiry and confirm it in the quotation.

What are the MOQ, lead time, warranty and delivery terms?

These commercial terms are not established by the supplied product material and must be confirmed during quotation.
