 * Connect the receiver signal 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
 
+As the speed/load increases, there can be a lot of noise in the PWM signal, triggering unwanted movements :
+* Keep cables short, use shielded cable, use ferrites, stabilize voltage
+* You can scratch the pcb and solder 100nf capacitors to ground, that will act as a RC filter and reduce the signal noise

 ## :control_knobs: Calibration:
 Proceed with [calibration](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Input-Calibration) for better control.<br>
 This variant is expecting only one mid-resting input, calibration will be rejected otherwise.
