4B5 Motor Drive Shield Expansion Board L293D For Arduino Mega2560 UNO

DESCRIPTION

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, 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. 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.
