It is a convenient way to adjust settings "on the go", at the field, for everyone.



FPV Combat board shall be flashed with compatible [firmware](https://github.com/FPV-Combat/Main_board_v2/releases).

**Gadget version 0.5.0+ requires FPV Combat version 2.8.0+.**

## Assembly

It is possible to [order the gadget](https://www.etsy.com/se-en/listing/1589030767/fpv-combat-gadget-battery-not-included) either fully assembled, as a kit or just PCB from [our shop on Etsy](https://www.etsy.com/se-en/shop/SkyGadgets).

Alternatively, you can always order PCB yourself from PCBWay, JLCPCB and alike or use 30x70mm prototype board.

### Assembly tips

- Once soldered, backs of pins/slots have to be filed out/flattened, otherwise risk of damaging the battery;

- Straighten encoder pins and cut them a bit, just a several mm;

- Cut a bit of encoder pcb, across mounting holes, otherwise it does not fit;

- HC-12 is placed white (flat) side up;

- Pull HC-12 antenna a little so it is away from everything to minimise interference.
