DEVMO L293D Motor Drive Shield Expansion Board Compatible with Ar-duino Duemilanove Mega UNO R3 AVR ATMEL

★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.
★2 interface for 5V Servo connected to the high-resolution dedicated timer – no jitter
★2 external terminal power interface, for seperate logic/motor supplies
