The Parallax HB-25 Motor Controller is our single best solution for DC motor control. This module is dependable and highly-compatible with any microcontroller that can generate a servo compatible pulse. In the simplest sense the HB-25 allows a DC Motor to be controlled much like a Continuous Rotation Servo. While the signals are compatible, the HB-25 does not require refreshing as a servo does; a single pulse can maintain the output.
