L293D Motor Control Shield Motor Drive Expansion Board

Overview

This motor driver expansion board is based on the L293D chip which is designed to drive up to 4 bi-directional DC motors with individual 8-bit speed selection. It can also drive 2 stepper motors (unipolar or bipolar), single coil or double coil, interleaved or micro-stepping. It contains 4 H-bridges which provide up to 0.6 A per bridge (1.2 A peak) at voltages from 4.5 V to 36 V.

This shield has pull-down resistors to keep the motors disabled during power up. It also features a 2-pin terminal block to ensure separate logic and motor external power supplies. This expansion board is compatible with Arduino Mega, Diecimila, and Duemilanove.

This motor driver shield is capable of driving:

• Four DC motors and two servos
• Two DC motors, stepper motor, and two-way servo
• Two stepper motors and servos
