Introduction: The Super F405HD ELRS AIO flight controller comes with integrated UART 2.4GHz ExpressLRS receiver and 20A Blheli_s ESC(Bluejay firmware pre-installed) which could support 2-4s battery. Bigger Mosfet could support high to 20A currents and reserved 6 pin socket for DJI HD equipment plug and play. It鈥檚 a great solution of build 2-4S HD digital FPV whoop.
