Factory firmware: F_H_40_REV16_7.HEX

Default protocol: DSHOT600

Bind procedure:

1.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”

2. 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 – all selectable in Betaflight

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
