HAKRC F7220D Flight Controller for FPV Drone – STM32F722, ICM42688, 20×20mm, DJI Compatible, 3S-6S Input

The HAKRC F7220D Flight Controller is a compact, high-performance F7 FC designed for FPV drones with a 20×20mm mounting pattern, offering advanced flight control capabilities in a mini form factor. Built around the powerful STM32F722RET6 processor, this board ensures reliable performance with fast loop times and rich connectivity options.

Equipped with a high-precision ICM42688 IMU, Infineon DPS310 barometer, and AT7456E OSD, the F7220D delivers accurate sensor data and full Betaflight OSD functionality. It also includes a 16MB blackbox for data logging and tuning.

The upgraded Type-C USB interface improves durability and ease of connection, while the built-in DJI plug provides plug-and-play support for the DJI FPV Air Unit. With 5 UART ports, the board is fully expandable for GPS, telemetry, and receiver modules.

This flight controller supports a wide range of receiver protocols including SBUS, ELRS, CRSF, DSMX, iBus, PPM, and others.
