This H-bridge board is an easy-to-use brushed DC motor driver that can handle large-size motors such as wheelchair motors, and winch motors. An H-bridge is an electronic circuit that switches the polarity of a voltage applied to a load. The circuit is built using 4 x N-Channel MOSFETs, gate driver IR2104, and a logic circuit. […]
