L293D Motor Driver/Servo Shield for Arduino 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, 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, Features : 1. Can drive 4 DC motors or 2 stepper motors or 2 Servos 2. 2 interface for 5V Servo connected to the high-resolution dedicated timer no jitter 2. Up to 4 bi-directional DC motors with individual 8-bit speed selection 4. Up to 2 stepper motors with single coil, double coil or interleaved stepping. 5. 4 H-Bridges: per bridge provides 0.6A (1.2A peak current) with thermal protection, can run motors on 4.5V to 36V DC 6. Pull down resistors keep motors disabled during power-up 7. Reset button 8. 2 external terminal power interface, for separate logic/motor supplies Package Includes : 1 x L293D Motor Driver/Servo Shield for Arduino
