Happymodel CruxF405HD ELRS 2-4S 3in1 AIO FC 20×20mm built-in UART ELRS RX and 20A ESC for Toothpick Drone HP-CruxF405

Happymodel CruxF405HD ELRS 2-4S 3in1 AIO FC 20×20mm built-in UART ELRS RX and 20A ESC for Toothpick Drone HP-CruxF405

The CruxF405HD 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 would be better for 2-4S toothpick drone or long range FPV drone. Reserved 6 pin socket for DJI HD equipment plug and play. It’s a great solution of build HD digital FPV drone .
