This variant can be used with Flysky RC Receivers compatible with IBUS protocol.
It will send all channels on a single wire like PPM, but is more reliable as it is a digital protocol using a USART frame and checksum.
Default number of channels for IBUS in config.h is 14.

Wiring:

  • Connect green wire to IBUS port of your receiver. By default, IBUS variant is using right sensor cable(shorter)

⚠ Red wire from sensor cable delivers 15v !!! Use 3.3v from programming port, 5v from hall sensor cable, or a voltage regulator.

Troubleshooting:

If the board is beeping

  • Check the number of channels, even if you transmitter only handles 6 channels, you receiver might transmit more channels
  • Make sure you enabled PPM on your transmitter
  • Make sure you are using the sensor cable(left or right) selected in config.h
  • On some boards the wire colors might differ, try the blue wire
