L293D Motor Driver Shield for Arduino Uno

L293D Motor Driver Shield

The L293D Motor Driver Shield for Arduino is probably one of the most versatile on the market and features 2 servo and 4 motor connectors for DC or stepper motors. That makes it a great shield for any robotic project.
This Arduino compatible L293D motor Driver shield is a full-featured product that it can be used to drive 4 DC motor or two 4-wire steppers and two 5v servos. It drives the DC motor and stepper with the L293D, and it drives the servo with Arduino pin9 and pin10.
The shield contains two L293D motor drivers shield and one 74HC595 shift register. The shift register expands 3 pins of the Arduino to 8 pins to control the direction of the motor drivers. The output enables the L293D motor driver shield is directly connected to the PWM outputs of the Arduino.

Firmware:

• Arduino Stepper/Servo software library with microstepping support.
• To install, click on Download in the top right corner, select zip and uncompress the folder.
• Rename the folder to AF-motor (check that the renamed folder contains the .cpp and .h files) and install it into the Arduino sketches/libraries folder. For information on how to use and install libraries, see our tutorial! This version now works with the Mega. Public domain!
• AccelStepper library with AFMotor support. This library allows for advanced stepper control including acceleration and deceleration, and concurrent stepper control!
• To install, click on Download in the top right corner, select zip and uncompress the folder.
• Rename the folder to AF-motor (check that the renamed folder contains the .cpp and .h files) and install it into the Arduino sketches/libraries folder.

Note:

• Power for the motors can be supplied from the Arduino boards DC Jack (normally 9V) or from the 2-pin EXT-PWR terminal block. If you are supplying power from the EXT_PWR terminal block you should remove the PWR jumper or you could damage the shield and the Arduino board.
• We have a variety of modules that can be interfaced with this L293D Motor Driver Shield. Some of them are listed below click on their name to know more
• Arduino Boards
• Servo Motors
• DC Motors
• 28BYJ-48 Stepper Motor

Features:

• 2 connections for 5V hobby servos connected to the Arduino’s high-resolution dedicated timer
• 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% 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/motor supplies
• Tested compatible with Arduino Mega and UNO
• Download the easy-to-use Arduino software library, check out the examples and you’re ready to go!
