What is SPI?

Basically, SPI is a communication protocol like UART, a serial communication protocol. A SPI connection requires 4 wires, while an UART connection only uses 2 (TX and RX). However SPI is faster than UART and places less stress on the processor.

Currently the built in Frsky receiver is compatible with Taranis, Taranis Plus, X9E, Horus X12S, XJT Modules with International Firmware (in D8 mode). Pay attention, this is a SPI connection receiver. In Betaflight Configuration, it should be setted as FRSKY_D receiver in SPI RX mode.


    1. Power the flight controller
    2. Hold the "bind" button for 2 seconds — the flashing green LED will turn solid
    3. Put your Taranis in to bind mode (using D8)
    4. The green LED should now be flashing indicating that binding is now complete.
