Model Number: L293D Brand Name: New and Original Key Specifications/Special Features: Motor driver module, L293D, expansion shield boardDescription: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 36V, that 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, such as motor.Features:
2 interface for 5V Servo connected to the 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 reset button
2 external terminal power interface, for separate logic/motor supplies
Tested compatible for Mega, Diecimila & Duemilanove
