Overview
The Holybro Kakute F722 Flight Controller is a high-performance, feature-rich FC designed for demanding FPV pilots and drone developers. Built on the STM32F722 MCU, it offers 216MHz processing, low-noise ICM42688P gyroscope, and versatile connectivity for ESCs, digital & analog VTX, GPS, SBUS receivers, WS2812 LEDs, and more.
With native support for Betaflight and INAV firmware (KAKUTEF7MINIV3 target), it is ideal for freestyle, cinematic, and long-range drone builds. Integrated 16MB Blackbox flash, AT7456E OSD, and support for up to 8S input voltage make it a reliable core for modern FPV systems.
