WHAT IT DOES

An h-bridge is an electronic circuit which can both turn on/off and reverse the direction of current in an output load such as the machining spindle's DC motor. This module uses pulse width modulation (PWM) to control the time-average voltage in the load.

WHAT YOU NEED

This is a self-contained module containing both control and driver ICs.
