HB-25 DC Motor Controller
By Parallax (29144)
The Parallax HB-25 Motor Controller is an elegant 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. But unlike the servo, the HB-25 does not require refreshing, meaning a single pulse can maintain the output, reducing the load on the microcontroller.
