+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.
+
+## Wiring:
+* Connect green wire to your receiver. By default, PPM variant is using right sensor cable(shorter) to minimize noise
+
+## Troubleshooting:
+
+If the board is beeping
+* Please 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
+
+⚠ Use 3.3v from programming port or a voltage regulator, don’t use red wire it delivers 15v
