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

Several improvements are made to the V1.2 to make the Poly AIO easier to solder and work with, and to meet pilots needs. Detailed improvements are as below.

  • 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.
