 There are 3 wave-forms the user can select: sine wave, triangle wave, and saw wave. The controller also is equipped with a low-voltage cutoff routine. This will dissable the throttle channel to prevent over-discharging a battery. The routine uses an analog-pin to read the input voltage via a voltage-divider.
