## Overview

The SainSmart L293D Motor Drive Shield is a high-quality, monolithic integrated driver designed for Arduino platforms. With its compact dimensions and robust capabilities, it allows for efficient control of motors in various applications, making it an essential tool for hobbyists and professionals alike.

## 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 25 Volts, that"s 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 the 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 25V DC. Pull down resistors keep motors disabled during power-up. 2 external terminal power interface, for separate logic/motor supplies. Tested compatible for Arduino Mega, Diecimila and Duemilanove.

## Features

- A monolithic integrated, high voltage, high current, 4-channel driver.
- Brand new and high quality.
- Size:6.8cm x 5.5cm x 2cm - 2.68inch x 2.17inch x 0.79inch.

    Well built clone but don't forget to check alternatives and understand limitations
  

*by P***. on Reviewed in the United States on December 23, 2014*

It's the AdaFruit Motorshield v1.0 clone and works fine. I did not realize that AdaFruit meanwhile has moved to v2.0 which uses a lot less pins and has a more versatile stackable design allowing to use multiple shields for even more motors.This one does what it needs to do. Be aware that you either need to use the AdaFruit library or be prepared to reprogram how the pins are used. The design uses a shift/latch to address the motors so the control is a little less direct than a typical HBridge design. Of course you can also use the L293D's directly they are in an IC socket and can easily be taken off the shield if you want to go that path (then it's cheaper to buy just the IC).Beware if you also need SPI communication (used a lot for RF modules) as It uses those pins for the motor control.You may notice that the board has spots for additional capacitors. I first thought they forgot them but it's the same on the original. I think that they are supposed to be used for extra noise suppression but it is better to put them closer to (or even on) the motors. I guess that's why they are missing: it's not as efficient as putting them closer to the source of the noise. It's also possible that they designed the board so clever that the open spots actually act as capacitors but I doubt it.

    Good little shield
  

*by T***J on Reviewed in the United States on February 27, 2013*

VERY easy to use with the Adafruit library.Does limit the use of other boards a bit, but you can see from the picture it doesn't have other headers.If you are using all of the motors, it does take up most of the digital IOs, but ONLY if you're using those motors:  All 6 analog input pins are available. They can also be used as digital pins (pins #14 thru 19)  Digital pin 2, and 13 are not used.  The following pins are in use only if the DC/Stepper noted is in use:  Digital pin 11: DC Motor #1 / Stepper #1 (activation/speed control)  Digital pin 3: DC Motor #2 / Stepper #1 (activation/speed control)  Digital pin 5: DC Motor #3 / Stepper #2 (activation/speed control)  Digital pin 6: DC Motor #4 / Stepper #2 (activation/speed control)The following pins are in use if any DC/steppers are usedDigital pin 4, 7, 8 and 12 are used to drive the DC/Stepper motors via the 74HC595 serial-to-parallel latchThe following pins are used only if that particular servo is in use:Digitals pin 9: Servo #1 controlDigital pin 10: Servo #2 control

    If you need more current than this can handle, Solder another set of L293D chips on top!
  

*by L***R on Reviewed in the United States on March 6, 2017*

Works with adafruit version 1 motor shield code.  All of the analog pins are open, just need header pins installed and you can use them for sensors.If you need more amp handling you can solder another set of the L293D chips right on top of the ones on here, They have parallel capability!I'm using this to make an autonomous car from a old new bright rc truck with a servo. Make sure you check the motor you plan on using this with under load with a multimeter to be sure you won't go over its rating! Cheap and decent board for powering motors can't beat it.
