Description: Motor Driver Expansion Board L293D Motor Driver Control Shield Guide

This Arduino compatible motor Driver shield is a full-featured products that it can be used to drive 4 DC motors or two 4-wire stepper and two 5V ”hobby” servo. It drive the DC motor and stepper with the L293D, and it drive the servo with Arduino”s 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 10 Volts, thats 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.

Specifications:

Logic Input voltage: 4.5 V ~ 7 V

Current Input: 13-26 mA

Output Current per driver: 600 mA

Pulsed Current per driver: 1.2 A

Output Voltage: 4.5V to 36 V

Size: 69 x 53 mm

Feature:

2 interface for 5V Servo connected to the high-resolution dedicated timer – no jitter!

Can drive 4 DC motors or 2 stepper motors or 2 Servo

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.

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 reset button

2 external terminal power interface, for seperat logic/motor supplies
