This variant can be used with PPM-SUM RC Receivers.
As opposed to PWM, it will send all channels on a single wire one after the other.
Default number of channels for PPM in config.h is 6 (Successfully tested Flysky fs-i6ab receiver with 8 channels).

Wiring:

  • Connect PPM port of your receiver to green wire on 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.

Transmitter configuration:

  • Enable PPM
  • Assign desired joystick to channel 1(steering) and channel 2(throttle)

Calibration:

Proceed with calibration for better control.

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 use the PPM port on your receiver
  • 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
