4 H‑Bridges Motor Drive Shield Expansion Module for Arduino Projects


 



Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil or interleaved stepping.
Up to 4 bi-directional DC motors with individual 8-bit speed selection.
2 interface for 5V Servo connected to the high-resolution dedicated timer - no jitter.
4 H-Bridges: per bridge provides 0.6A (1.2A Maximum current) with thermal protection.
Can drive 4 DC motors or 2 stepper motors or 2 Servo.
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: 
Pull down resistors keep motors disabled during power-up.
Built In Reset Button.
2 external terminal power interface, for separate logic/motor supplies.
Specification:
Motor voltage: 4.5V-36V
Current: ≤1A
PCB size: 6.7*5.3cm / 2.64*2.09in
Color: As picture shown
