DC Motor/Stepper/Servo Driver Shield for Arduino Water Purity This is why it's calledDC Motor Stepper Servo Driver Shield for Arduino (L293D) is a dual channel H Bridge motor driver capable of driving a pair of DC motors or single stepper motor. The shield offers total 4 H Bridges and each H bridge can deliver up to 0. 6A to the motor. It can drive up to 4 bi directional DC motors with individual 8 bit speed selection (so, about 0. 5% resolution). It can drive up to 2 stepper motors (unipolar or bipolar) with single coil, double coil,
