GEPRC GEP-F405-HD V2 Flight Controller – STM32F405, 3–6S, 9V/5V Dual BEC, DJI Plug, 30.5x30.5mm for FPV Drones

Overview

The GEPRC GEP-F405-HD V2 is a feature-rich, cost-effective flight controller built for 3–5 inch FPV drones, especially HD builds using DJI Air Unit or Vista systems. Powered by the reliable STM32F405 MCU and equipped with the ICM42688-P gyro, it delivers stable, responsive flight control. With 6 UARTs, dual BEC outputs (5V@3A and 9V@2.5A), and direct plug-and-play DJI compatibility, it provides everything you need for a clean, powerful digital FPV setup. Ideal for freestyle quads, cinewhoops, or mid-range cruisers running up to 6S LiPo.
