L293D Stepper Motor Driver Board Control Shield Module Motor Drive Expansion Board 4.5-16V DC For Arduino Mega2560 in Qatar
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.
Features:
- 2 interface for 5V Servo connected to For 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 16V DC
- Pull down resistors keep motors disabled during power-up
- reset button
- 2 external terminal power interface, for seperate logic/motor supplies
- Tested compatible for Aduino Mega, Diecimila & Duemilanove
