The Parallax Little Step-U Motor Controller performs all calculations and operation of the motor. The desired operating speed, ramp time and drive mode can be configured once and then a single command used as required, to move to fixed or relative positions. While the motor is in motion, a busy output is active and the movement can be optionally interrupted by one of the two external inputs.
