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 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.

Diagram for F4 1S 12A AIO FC

UART1, UART2, and SBUS pads are left for external receivers like Frsky XM+, TBS Nano receiver so that a long receiver range is available.

Buzz pads (BUZZ+ and BUZZ-) are invalid directly. It needs some modification to make it works.

The current meter is integrated on the FC board. Here is the configuration in Betaflight Configurator.

12A 1S ESC

Should we really need a 12A ESC for 1S drones? If it is a 65mm or 75mm Whoop drone like Meteor65, 5A ESC is enough for all actions. But how about with 3" propellers and 1102/1202.5 motors? Still, want smooth and powerful flying actions? The 5A ESC has developed about 3 years ago and designed for whoop drones with 0603/0802 motors. For the past year, the BETAFPV team has been cooperating with BLHeli author Steffen on the 12A 1S ESC for 3" toothpick drones. Finally, it is here!

It marks "1-2S" on the board, could this FC board support 2S?

NOT Yet. The motor spins not smoothly in 2S power with the released ESC firmware. We will work on it continuously and make this board support 2S later. If you have any ideas or advice, feel free to contact us.

SPI Frsky RX

Come with the build-in SPI Frsky Receiver (CC2500 chip), F4 1S 12A AIO FC can be compatible with Futaba S-FHSS, Frsky D8, and D16 protocol. The default protocol is configured to Frsky D16 FCC out of the factory. Pilots could set up the protocol according to your own need in Betaflight Configurator.
