BETAFPV has come up with their F4 1S 12A AIO Flight Controller which is suitable for 3" lightweight builds and toothpick drones like the HX115 SE 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 12A  AIO FC V1.0  ELRS is definitely your best choice!

Features

• F4 1S 12A AIO Flight Controller is the best choice for building ultra-lightweight 3" toothpick drones like HX115 SE FPV Quad.
• Most of the 1S flight controllers on the market come with 5A ESC by now, but this FC especially integrates 1S 12A ESC, it can provide more sufficient power for 3" toothpick drones.
• Built-in current meter, 2 programmable RGB LEDs, and SPI Frsky receiver. At the same time, all the pads are left for the external receivers with UART1 and UART2, for buzzers, etc.
• Whoop mounting hole pattern, be compatible with most 1S 3" frame. Large pads are reserved for solder motor cables, this design will make solder easier.
