F4 AIO 1S Brushless Flight Controller 12A ELRS 2.4GHz

F4 1S 12A AIO Flight Controller - a 1S 12A FC for building lightweight 3" toothpick drones like the HX115 SE Toothpick Drone and HX115 LR Toothpick Drone. If you want to try a bigger FPV drone than 65mm/75mm on 1S power, and still want smooth and powerful flying actions, this FC that integrates 1S 12A ESC is definitely your best choice.

Integrated ELRS receiver

What is the update of the ELRS 2.4G V2.0 board?

Support both 1S and 2S battery now. Only 1S supported on V1.0.
Use SPI ExpressLRS 2.4 receiver with Betaflight firmware.
Modify the shape of the board to support 85mm whoop frame. Only toothpick frame supported on V1.0.
Uses the lighter and smaller SH connector instead of USB Type-C for connecting to your PC.

Note: The default flight controller firmware only supports ELRS V1.0. However, this flight controller can work with ELRS V2.0 by flashing the Betaflight V4.3.0 RC1-RC3 firmware. The target file name is BETAFPVF4SX1280.
