wiat what? lol.
i have 2 pins, either has to be high at one point or another. i don't see how you're getting it so that only 1 pin is needed. i can supply the 5 v for the enable pins and vss pin from the battery, sure, but i got 4 more inputs to control. 2 controllers, cause there's 2 drive motors and 2 servo motors.
are you saying to PWM the enable pin in order to get it to move slower or faster?
