If your motor require more than 9V we recommend that you separate the power lines of the shield and the Arduino board on which the shield is mounted. This is possible by cutting the \"Vin Connect\" jumper placed on the back side of the shield.

You can drive two Brushed DC motors by connecting the two wires of each one in the (+) and (-) screw terminals for each channel A and B. In this way you can control its direction by setting HIGH or LOW the DIR A and DIR B pins, you can control the speed by varying the PWM A and PWM B duty cycle values. The Brake A and Brake B pins, if set HIGH, will effectively brake the DC motors rather than let them slow down by cutting the power. You can measure the current going through the DC motor by reading the SNS0 and SNS1 pins. On each channel will be a voltage proportional to the measured current, which can be read as a normal analog input, through the function analogRead() on the analog input A0 and A1. For your convenience it is calibrated to be 3.3V when the channel is delivering its maximum possible current, that is 2A.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style='font-family:\"Open Sans\", Roboto, Arial, Helvetica, sans-serif, SimSun;line-height:inherit;color:rgb(34, 34, 34);background-color:rgb(255, 255, 255);margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;padding:0px;padding-bottom:0px;padding-top:0px;padding-left:0px;padding-right:0px;box-sizing:border-box'\u003e\u003cspan style='font-size:18px;font-family:\"Times New Roman\"'\u003ePhysical Characteristics :\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style='font-family:\"Open Sans\", Roboto, Arial, Helvetica, sans-serif, SimSun;line-height:inherit;color:rgb(34, 34, 34);background-color:rgb(255, 255, 255);margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;padding:0px;padding-bottom:0px;padding-top:0px;padding-left:0px;padding-right:0px;box-sizing:border-box'\u003e\u003cspan style='font-size:18px;font-family:\"Times New Roman\"'\u003eThe maximum length and width of the Motor Shield PCB are 2.7 and 2.1 inches respectively.
