L293D Arduino Motor Driver Shield Product Description

L293D Arduino Motor Driver Shield

Product Description

Arduino is a great starting point for electronics, and with a motor shield it can also be a nice tidy platform for robotics and mechatronics. Here is a design for a full-featured motor shield that will be able to power many simple to medium-complexity projects. 2 connections for 5V 'hobby' servos connected to the Arduino's high-resolution dedicated timer - no jitter! Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution) Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping. 4 H-Bridges: L293D chipset provides 0.6A per bridge (1.2A peak) with thermal shutdown protection, 4.5V to 25V Pull down resistors keep motors disabled during power-up Big terminal block connectors to easily hook up wires (10-22AWG) and power Arduino reset button brought up top 2-pin terminal block to connect external power, for seperate logic/motor supplies Tested compatible with Mega, Diecimila, & Duemilanove.

The shield 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.

To increase the maximum current, the L293D allows extra chips with "piggyback". Piggyback is soldering one or two or three extra L293D drivers on top of the L293D drivers on the board to increase the maximum current. The L293D allows parallel operation.

The Motor Shield is able to drive 2 servo motors, and has 8 half-bridge outputs for 2 stepper motors or 4 full H-bridge motor outputs or 8 half-bridge drivers, or a combination.

The servo motors use the +5V of the Arduino board. The voltage regulator on the Arduino board could get hot. To avoid this, the newer Motor Shields have connection points for a separate +5V for the servo motors.
