L293D L293 293 DC Motor Driver Control Shield 74HC595 Expansion Board for Arduino UNO & MEGA Servo & Stepper Motor

This is a full-featured motor shield for Arduino, which is able to power many simple to medium-complexity projects.

Features:

-     2 connections for 5V 'hobby' servos connected to the Arduino's high-resolution dedicated timer
-     4 H-Bridges: L293D chipset provides 0.6A per bridge (1.2A peak) with thermal shutdown protection, internal kickback protection diodes. Can run motors on 4.5VDC to 25VDC.
-     Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution)
-     Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil or interleaved stepping.
-     Pull down resistors keep motors disabled during power-up
-     Big terminal block connectors to easily hook up wires (18-26AWG) and power
-     Arduino reset button brought up top
-     2-pin terminal block and jumper to connect external power, for separate logic/motor supplies (remove the jumper to use different power supplies for Arduino and motors)
-     Tested compatible with Arduino Mega 2560 and UNO

Product features:(MINI)
. Scope of application: Arduino beginners,Arduino experimentalequipment platform,Arduino interactive electronics,Arduino robots,etc.
. Features: many functions,easy to operate,a powerful driver librarysupport and function update.
.Disadvantages: High l/O consumption when driving a four-waymotor at the same time (compared to the version with less L/O inthe AR-Duino),low power.
