FPV Electronics > Flight Controller
F722 Flight Controller is built around the STM32F722 32-bit processor, which operates at 216MHz, providing exceptional processing capabilities for flight stabilization and control.
The F722 Flight Controller is a high-performance flight control board designed for FPV drones, leveraging the STM32F722 microcontroller (ARM Cortex-M7) for fast processing, advanced filtering, and smooth flight characteristics. It’s widely used in racing, freestyle, and even long-range builds due to its balance of power and affordability.
