Product Discription
This L293D is a monolithic integrated, high voltage, high current, 4-channel driver. With this you can use DC motors and power supplies of up to 36 Volts, It can drive some pretty big motors and it 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. motor
Features:
2 interfaces for 5V Servo connected to the Arduino's 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
Arduino reset button
2 external terminal power interface, for seperate logic/motor supplies
compatible with Arduino Mega, UNO & Duemilanove
Package includes:
1 X L293D Motor Drive Shield module Expansion Board
To improve the thermal quality we recommend to stick 2 heatsinks on the L293.
