Holybro Kakute H743-Wing Flight Controller — a powerful and reliable controller for fixed-wing models and VTOL projects from Holybro. This module combines high computing power, a rich set of interfaces, and readiness for integration with modern autopilot systems, making it an excellent choice for professionals and hobbyists.
Device Overview
The Kakute H743-Wing is based on the STM32H743 processor with a clock speed of 480 MHz, equipped with 1 MB of RAM and 2 MB of flash memory. For precise orientation, a high-precision ICM-42688P (SPI3) IMU is used, and altitude is determined by the built-in BMP280 (I2C4) barometer. This platform ensures stable autopilot operation even in complex flight conditions.
