I am familiar with using PWM on Arduino and have done so with simple 3-pin interfaces: e.g. PWM, DIR (direction) and GND pins. Choose a direction with DIR, set speed with PWM in software (0 - 255), simple stuff.
But this board I'm buying seems different:
There seems to be 6 control pins:
R_IS, R_EN, RPWM, L_IS, L_EN, LPWM
But from what I understand this board would only be used for controlling one motor bidirectionally, so why is there a distinction between left and right?
So how would I go about using this motor driver board in a similar way to my
PWM, DIR, GND boards that I've used before to control the motor direction and speed?
