Dual Channel 12A DC Motor Driver Board

SKU: DFR0601

This is a 1.97”×1.97”×0.49” dual-channel DC motor driver. It drives two motors simultaneously, with blue (forward)/red (reverse) direction indicators per channel. Supports 6.5V-37V, 12A continuous current per channel (max 290W), 70A peak current (100ms). PWM min pulse width is 2us for better control. Integrated over-voltage/under-voltage/overheat protection: STATE light (ON=normal, fast flash=over-voltage, slow flash=under-voltage, double flash=overheat; protection triggers turn off output). Works with Arduino for easy motor control.
