A serious fixed-wing pilot can count on the Holybro Kakute H743 Wing flight controller for powerful operation and reliable performance. Equipped with the STM32 H743 Processor running at 480 MHz, CAN Bus support, dual camera support & switch, 9V/12V ON/OFF Pit Switch, and plug-and-play GPS, and I2C ports, this controller is designed for fixed-wing & VTOL applications. Featuring an intuitive layout, it works with INAV and Ardupilot systems for rapid setup and precise control. 

Choose between having the pin headers solder on or loose.
