Simplify your HD build and experience locked-in flight performance with the GEPRC GEP-F405-HD V3 Flight Controller. Engineered specifically to accommodate modern digital FPV systems, this highly capable 30.5×30.5mm flight controller takes the headache out of wiring while delivering the processing power and ultra-smooth gyro data required for cinematic video and aggressive freestyle.
Plug-and-Play DJI Integration
Say goodbye to tedious micro-soldering for your video system! The GEP-F405-HD V3 features a dedicated connector that plugs directly into the DJI Air Unit, getting your HD video feed up and running in seconds. To support power-hungry digital transmitters, the board is equipped with beefy dual independent BECs (5V@3A and [email protected]), ensuring your electronics receive clean, uninterrupted power without browning out during throttle punches.
Next-Gen Gyro & Filtering
At the heart of this flight controller is the reliable STM32F405 MCU paired with the latest ICM42688-P gyroscope. To guarantee your HD footage is completely jello-free, GEPRC has integrated an onboard LC filter to clean up electrical noise and included specialized silicone shock-absorbing grommets that isolate the sensitive gyro from physical frame vibrations.
