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

  • 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 receiver like TBS Crossfire.

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

We also carry the Toothpick F4 20A FC V2!

    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.

    Here is a video of detailed introduction for 20A AIO FC, made by Jon E5 FPV.

    Features

    • This new board can handle 20A continuous current(25A burst), which is the first 20A All-in-one FC on the market
    • Comes with 4*Motor Pluggable Pins and Not Pre-solder in default, fits your needs of self-assembly best
    • Compatible with 120X, 130X, 140X motors, and 1505 motors
    • USB port is mounted on the side, you have more possibilities of mounting it while still maintaining access to the USB port
    • All of the solder pads are at the edge of FC, which is a convenience to solder
    • Double-sided motor solder pad. Pins pad and wires pad are both built-in for motors connection
    • Integrated with a Betaflight MATEKF411 processor FC, Betaflight  OSD, F4 MCU, and 20A ESC, support 2-4S battery

    PARTS UPDATED

    • Integrated 24 single N-channel MosFETs chips on 20A AIO FC board, which has a lower inner resistance. 12A AIO FC board adopts 12 dual MosFETs chips instead. Current sensor included.

      Double-sided Motor Solder Pad
      Support connect with motors via connectors or solder directly Mounting Pattern and Real Holes of Mounting Holes
      This board comes with standard 26.5x26.5mm mounting holes, which can install easily in most whoop and toothpick frames.

      Status LED

      There are 3 LEDs on the bottom of the board to indicate the status, including Receiver LED ( Green), FC Status LED ( Blue ) and FC Power LED ( Red ). 

      LED  Status  Description
      Mode LED (Green)  Solid Horizon Mode/ Angle Mode
      Mode LED (Green)  Extinguished Acro Mode
      Power LED (Red)  Solid  Power on
      Status LED (Blue)  Solid  Motor Armed


      Built-in CURRENT METER

      You could get a more accurate current value without using the virtual current meter. In order to use this current sensor hardware, some configurations in Betaflight GUI are needed. In the "Power & Battery" tab:

      Note: You may need to slightly adjust offset at Amperage Meter after connecting electronic components, such as VTX, camera, and motor.

      Then when flying, you could find the real current value from the OSD information. Of course, the current sensor is configured well in the factory and you do not need to change it as usual.

      Know more about current sensor and calibration.
