L293D-MD motor driver is a simple and reliable DC motor driver. This motor driver can handle current up to 1 ampere. The design is dedicated for those who does not have much time in developing a small dc motor driver for projects application. It also helps to minimize soldering error and maximize the time use for other applications.

Specification:

• Supply Voltage: 5V to 12V
• Logic Supply Voltage: 5V to 12V
• Maximum output current : 1 A
• Output: Up to 2 DC motor
• Direction control signal input : 4
• Speed control signal input : 2

L293D Motor Driver/Servo Shield for Arduino is probably one of the most versatile on the market and features 2 servo and 4 motor connectors for DC or stepper motors. That makes it a great shield for any robotic project. This Arduino compatible motor Driver shield is a full-featured product that it can be used to drive 4 DC motor or two 4-wire steppers and two 5v servos. It drives the DC motor and stepper with the L293D, and it drives the servo with Arduino pin9 and pin10. L293D is a monolithic integrated, high voltage, high current, 4-channel driver. Basically, this means using this chip you can use DC motors and power supplies of up to 36 Volts, that some pretty big motors and the chip can supply a maximum current of 600mA per channel, the L293D chip is also what’s known as a type of H-Bridge. The H-Bridge is typically an electrical circuit that enables a voltage to be applied across a load in either direction to an output, e.g. a motor.

• Compatible with Arduino
• 2 Interface for 5V Servo Motor connected to the Arduino
• High-resolution dedicated timer
• 4 H-bridges: per bridge provides 0. 6A (1. 2A peak current) with thermal protection,
• Can run motors on 4. 5V to 36v dc
• Pull-down resistors keep motors disabled during power-up with Arduino reset but
• Can drive 4 dc motors or 2 stepper motors or 2 servos up to 4 bi-directional dc motors with individual 8-bit speed selection up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, or interleaved stepping.
