The classical Toothpick F4 Brushless FC 20A V3 board restocks now. 

The V3 version has all the functions of the V2 board, also add the following 2 additional functions.

  • Add 8M Flash chip for Betaflight Black Box.
  • 3 full UARTs (UART1, UART2 and UART6) are available in the V3 version. Pilots could use one UART for DJI digital FPV unit or Caddx Vista digital FPV unit and the other UART for external receivers like TBS Crossfire.

The V2 board only has one full UART and could not support DJI digital FPV VTX.


    For a new generation of toothpick drone,this new AIO Brushless FC can handle 20A continuous current(25A burst), which is the first 20A All-in-one FC on the market. Compared to FC / ESC Stacks design, this board provided with massive levels of performance capability while still maintain ultralight only 6.63g. Breaking through the limit of toothpick power, exploring more possibilities in 3''-4'' drones. This board is your best choice to DIY your own toothpick drone that is tailored to your requirements.
