TUNERC POLY F405 20A AIO Flight Controller – 2S/4S FPV Drone Board

Poly AIO V1.2 is Here. The OG Poly F405 AIO is Getting Better.

Versatile and High Performance AIO for Micro Community

This Poly F405 2S-4S AIO is designed for FPV micro community and it’s made to be super versatile so pilots can use this it in different builds like agile micro or long range quad or creative X6/X8 quads.
The AIO board has integrated blackbox, current meter and features 5 UARTs to suit needs for different builds. Apart from versatility, we have made this AIO board high performance to make sure it could hold up well on powerful quads. To achieve this goal, this AIO board comes with powerful F405 chip and high quality 20A mosfets and excellent heat dissipation ability.

- Bigger and easier to access battery lead and capacitor soldering pads.
- Bigger flash blackbox. The blackbox flash is updated from 4Mbyte to 8M flash. Pilots can now record more flying data, which makes the tuning easier.
- New inverter is used. Now, you don’t need to bridge the jumper pads any more. Just wire the SBUS receiver to the UART4, and you are good to go.
- Higher current 3.3V LDO is featured onboard, the power supply is much improved. 

Suitable for Lightweight Toothpick and Cinewhoop

The Poly AIO V1.2 is easy to use, light weight and versatile. Big soldering pads, reasonable pad layout and easy to access battery leads, all of these features make the Poly F405 V1.2 AIO really easy to solder and work with.  It also features a bigger blackbox 8M flash, now you can record more flying data. And 5UARTs onboard mean you will not be short of UART anymore. So whether you build toothpick, cinewhoops or longrange quads, Poly F405 2S-4S V1.2 AIO get you all covered.

Recommended Builds

The Poly V1.2 AIO is suitable for light 3″ sub250g builds. It supports motors ranging from 1102~1104, 1202~1204, 1303, to 1404 motors. 1404 is the largest motor the Poly V1.2 supports, please avoid using high kv option like 6000kv 1404 motors. And for 1404 4s build, we highly recommend you solder the capacitor directly to the capacitor soldering pads.

Note about the FC Firmware Preflashed to the Poly F405 V1.2

The default betaflight firmware version on the Poly V1.2 is 4.5.1, because the version limits and the product testing needs, the default settings are CRSF protocol and analog OSD mode. For HD digital and other receiver users, please reflash the firmware to include HD OSD options and other receiver protocols.
