Holybro Kakute H743 Wing Flight Controller for Fixed-Wing / VTOL

Holybro Kakute H743 Wing Flight Controller for Fixed-Wing / VTOL

Product description

The Holybro Kakute H743 Wing Flight Controller was specifically designed for modern fixed-wing, VTOL, and long-range platforms, combining tremendous computing power with versatile connectivity options and professional features for demanding flight projects. Whether it’s an FPV aircraft, a VTOL platform, an autonomous mapping system, or a high-end INAV or ArduPilot build—this flight controller delivers the performance and flexibility required by modern aviation electronics.

At its core is a powerful 480 MHz STM32H743 processor that effortlessly handles even complex flight calculations, sensor fusion, and autonomous flight modes. This is no longer just an ordinary flight controller—it’s more like a tiny aviation computer with a caffeine problem.

The integrated ICM-42688P gyro ensures extremely precise attitude calculations with low noise, while the built-in BMP280 barometer enables reliable altitude measurements. Both INAV and ArduPilot are supported, making the Kakute H743 Wing ideal for everything from classic FPV fixed-wing aircraft to fully autonomous VTOL systems.

Particularly convenient are the numerous integrated BEC outputs at 5V, 6V/8V, and 9V/12V, which allow servos, GPS, VTX, cameras, or gimbals to be powered directly. Additionally, the controller offers a dual-camera input with switching, a pit switch for VTX voltage, CAN bus support, and plug-and-play ports for GPS, I2C, and external sensors.

With a total of 14 PWM outputs, multiple UARTs, and a CAN interface, the Kakute H743 Wing is perfect for complex aircraft and VTOL configurations with multiple motors, servos, and auxiliary systems.

In short: This board is like a Swiss Army knife for aircraft geeks. Only with significantly more telemetry and fewer toothpicks.
