F4 AIO FC 12A V2 is upgraded in these 2 spark points.

  • Add 8M Flash chip for Betaflight Black Box. More details please check it here.
  • 3 full UARTs (UART1, UART2 and UART6) are available. 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.

Also this board is light only 5.07g and suitable for brushless whoop like 2S Pro 2 Series/ X Series. Integrated with a Betaflight MATEKF411 processor FC, Betaflight OSD and 2-4S 12A ESC which can support 4S battery for fast flying experience.

    Could the ESC on this AIO board support really 4S battery?

    Yes. But please pay more attention to the motors. Here are two situations that the motor will burn itself and then the ESC frequently. 

    Situation 1: The motor's KV value is too high and could not stand the 4S power. For example, the BETAFPV 1105 6000KV motors could not stand the 4S power in aggressive flying. So we are working on a lower KV 1105 motor that could use with 4S battery. It will be released soon.

    Situation 2: A poor quality motor will result in the fire accident in 4S power.

    For the moment, no 0x0x/1102/1103 motors could stand 4S power for the moment in the market. Please make sure your motors could support the 4S battery before any try.

    Here is the connection diagram with DSMX FullSpeed receiver.

    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

    This is our first whoop FC board that have current sensor built-in. So no need to use the virtual current meter and you could get a more accurate current value. In order to use this current sensor hardware, some configurations in Betaflight GUI are needed. In the "Power & Battery" tab:

    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.
