This variant can be used with Pulse Width Modulation RC Receivers.
## Configuration/Parameters
CONTROL_PWM_RIGHT is for the right sensor cable and is set by default to limit the noise as this cable is shorter.<br>
You can use CONTROL_PWM_LEFT instead if you need to use the left sensor cable.<br>
DEBUG_SERIAL will be automatically enabled on the opposite cable.<br>
## Wiring:
* Connect channel 1(steering) of your receiver to blue wire and channel 2(speed) to green wire. By default, the right sensor cable(shorter) is used to limit the noise
* Connect channel 1(steering) of your receiver to blue wire and channel 2(speed) to green wire of the cable selected in config.h
* PWM is highly prone to noise : keep cables short, use 100nf capacitors, use shielded cable, use ferrites, stabilize voltage
⚠ Red wire from sensor cable delivers 15v !!!

## Troubleshooting:
If the board is [beeping](https://github.com/EmanuelFeru/hoverboard-firmware-hack-FOC/wiki/Diagnostics)
* Make sure you are using the sensor cable(left or right) selected in config.h
* Make sure you are using the sensor cable(left=CONTROL_PWM_lEFT or right=CONTROL_PWM_RIGHT) selected in config.h
* You might have a defective input, because of a fried resistor or MCU pin (e.g. [issue](https://github.com/EFeru/hoverboard-firmware-hack-FOC/issues/244)), you can configure the firmware to work on the other cable
