Features:

25.5×25.5mm 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
