Simple Labs SLAEX039 L293D Motor Shield for Arduino Price & Reviews




The L293D Motor Shield is a very useful shield with standard components. It contains two L293D motor drivers and one 74HC595 shift register. The shift register expands 3 pins of the Arduino to 8 pins to control the direction for the motor drivers. The output enable of the L293D is directly connected to PWM outputs of the Arduino. 2 connections for 5V ‘hobby’ servos connected to the Arduino’s high-resolution dedicated timer: no jitter! 4 H-Bridges: L293D chipset provides 0.6A per bridge (1.2A peak) with thermal shutdown protection, internal kickback protection diodes. Can run motors on 4.5VDC to 25VDC. Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5 percent resolution) Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil or interleaved stepping. Pull down resistors keep motors disabled during power-up Big terminal block connectors to easily hook up wires (18-26AWG) and power Arduino reset button brought up top 2-pin terminal block and jumper to connect external power, for separate logic or motor supplies

Using this chip you can use DC motors and power supplies of up to 36 V, so that some pretty big motors and the chip can supply a maximum current of 600mA per channel
Also known as a type of H-Bridge, which is typically an electrical circuit that enables a voltage to be applied across a load in either direction to an output, e.g. motor
