 PPM_NUM_CHANNELS is the number of channels for PPM and is 6 by default. As an example Flysky fs-i6ab receiver is sending 8 channels even when used with a 6 channel transmitter<br>
 
 ## Wiring:
+* Connect your receiver VCC to 3.3v from programming port, 5v from hall sensor cable, or a voltage regulator, ⚠️ Red wire from sensor cable delivers 15v !!!
 * Connect PPM port of your receiver to green wire on right sensor cable(shorter)
+* Connect the receiver to ground, ⚠️ On some boards, the black wire is 15v !!! Check with a multi-meter to make sure 15V and ground are not swapped
 * PPM is highly prone to noise : keep cables short, use 100nf capacitors, use shielded cable, use ferrites, stabilize voltage
