Holybro Kakute H743-Wing Flight Controller

The Holybro Kakute H743-Wing is a flight controller laid out for fixed-wing aircraft and VTOL builds, running INAV (6.1.1 and later) or ArduPilot (4.4 and later) on a 480 MHz STM32H743. It takes 3S–8S input and carries its own servo and video BECs. Choose the FC on its own, or the bundle with the Holybro Micro M10 GPS module for a complete navigation setup.

Key features

• Built-in power rails: 5 V, a 6 V/8 V selectable servo rail rated 6 A continuous, and a 9 V/12 V rail for video gear, so most planes need no separate BEC.

• Pit switch on the 9 V/12 V output cuts power to the VTX and camera while you work on the bench.

• Dual camera inputs with an onboard video switch.

• CAN bus plus plug-and-play GPS, CAN and I2C ports for DroneCAN peripherals, an external compass or an airspeed sensor.

• Onboard voltage and current sensing rated 90 A continuous, 220 A peak.

• 14 PWM outputs for motors and servos on flying wings, V-tails and quad-plane VTOLs.

The board mounts on a 25 x 25 mm M2 pattern rather than the usual 30.5 mm or 20 mm stack, so check the tray in your fuselage before ordering; the 13.5 mm height suits slim wing bays.
