FPV Electronics > Flight Controller
The F405 Flight Controller is a high-performance flight control system designed for FPV drones and UAV applications. Built around the STM32F405 microcontroller (ARM Cortex-M4 @ 168MHz), it provides reliable flight control with optimized processing efficiency. Suitable for racing drones, freestyle FPV, and intermediate autonomous operations.
