4 2011-07-08 SparkFun <p> <span style="font-weight: bold;">Description:</span> The new version of this shield allows for either 3.3 or 5v logic, a separate and more robust VIN connection, and the PWM input has moved to pin 3.</p> <p> This is a motor shield for Arduino&nbsp;that will control two DC motors. Based on the L298 H-bridge, the Ardumoto can drive up to 2 amps per channel. The board takes its power from the same Vin line as the Arduino board,&nbsp; includes blue and yellow LEDs to indicate active direction, and all driver lines are diode protected from back EMF.<br /> <br /> Control for motor attached to OUT1/2 is connected to digital line 12 (direction A) and digital line 3 (PWM A).<br /> <br /> Control for motor attached to OUT3/4 is connected to digital line 13 (direction B) and digital line 11 (PWM B).<br /> <br /> Compatible screw terminals and connectors are listed below.<br /> <br /> <span style="font-weight: bold;">Documents:</span></p> <ul> <li> <a classname="" href="http://www.sparkfun.com/datasheets/DevTools/Arduino/Ardumoto_v13.pdf" target="_blank">Schematic</a></li> <li> <a classname="" href="http://www.sparkfun.com/datasheets/DevTools/Arduino/Ardumoto%20v13.zip" target="_blank">Eagle Files</a></li> <li> <a classname="" href="http://www.sparkfun.com/datasheets/Robotics/L298_H_Bridge.pdf" name="" target="_blank">L298 H Bridge data sheet</a></li> <li> <a href="http://www.sparkfun.com/datasheets/DevTools/Arduino/Ardumoto_test_3.pde" target="_blank">Example Arduino sketch</a></li> <li> <a href="http://www.sparkfun.com/commerce/tutorial_info.php?tutorials_id=183" target="_blank">Assembly Guide</a></li> <li> <a href="http://www.sparkfun.com/commerce/tutorial_info.php?tutorials_id=195" target="_blank">Quickstart Guide</a></li> </ul> <p> <strong>Replaces:</strong> <a href="http://www.sparkfun.com/commerce/product_info.php?products_id=9213" target="_blank">DEV-09213</a></p> Arduino Motor Shield http://www.sparkfun.com/products/9815 Motor Moto ArduMoto Motor Shield No GND
