SPI Frsky Receiver

Currently the built in Frsky receiver is compatible with Taranis, Taranis Plus, X9E, Horus X12S, XJT Modules. Pay attention, this is a SPI connection receiver. In Betaflight Configuration, it should be setted as FRSKY_D receiver (aka Frsky D8 mode) or FRSKY_X receiver (aka Frsky D16 mode) in SPI RX mode.

 

The Frsky D16 unstable connection issue is totally resolved since Betaflight 3.4.1. Nowadays, the default configuration from factory is Frsky D16 mode (FRSKY_X).

So the pilot who has a Frsky radio transmitter with EU firmware could use this FC board in D16 mode directly.

Binding Procedure

The binding procedure is reversed as usual. No need to click the bind button when power on.

  • Power on the board, either by connecting the battery or USB power. Then the green receiver LED start to flash.
  • The second step, click the bind button for 3s. Then the green receiver LED will be solid on. This means that the receiver is in bind mode and you could start to bind your radio transmitter.

For detail procedure of binding, please check the SPI Frsky Receiver Binding Manual.
