F722 Mini Flight Controller Technical Brief

Descriptions

The F722 Mini Flight Controller is a high-performance flight control system designed for compact FPV drones and UAV applications. Built around the STM32F722 microcontroller (ARM Cortex-M7 @ 216MHz), it delivers ultra-low latency processing and advanced flight dynamics. Featuring redundant sensors and dual BEC outputs, it is optimized for racing, cinematic filming, and long-range autonomous missions in space-constrained builds:cite[2]:cite[9].
