  Features:

  25.5x25.5mm Flight Controller AIO ESC board for toothpick .

  Most powerful for whoop / toothpick style flight

  Supports 2-4s battery input and provides 20A to the motors.

  Also Integrated SPI Frsky receiver working with D8/D16 protocols.

  This integrated receiver has PA/LNA power amplifier and the diversity antenna.

  This should give more control range for this flight controller.

  Bind procedure:

  Make the on board receiver get into bind mode: For 4.0.x version firmware Plug USB and then connect betaflight configurator and then move to CLI tab , type “bind_rx_spi” ,the Red LED on the top of the flight controller will getting to be solid , the onboard receiver is in bind mode; For 4.1.x or 4.2.x the bind code is “bind_rx”

  Make your transmitter get into bind mode . If bind is successful the red led will starting to blink. The red LED wouldn’t blinking when binding with some new ACCESS firmware frsky radio , but the bind is actual successful , need to go to CLI command and type “save” to finish the binding .

  SPI Receiver option:

  Frsky_D compatible with Frsky D8 protocol

  Frsky_X compatible with Frsky non-eu D16 protocol

  Frsky_X_LBT compatible with Frsky EU-LBT D16 protocol (4.0.X or latest betaflight firmware support)

  SFHSS compatible with Futaba S-FHSS protocol

  Package Included:

  1x F4 Flight Controller w/ Built-in 20A BL_S ESC & Frsky Receiver
