Variant PPM

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 green wire to your receiver 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.

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 are using the sensor cable(left or right) selected in config.h
• On some boards the wire colors might differ, try the blue wire
