Description How To More Details
 

You'll probably need a Official Arduino Motor Shield if you're planning to build a robot with an Arduino to drive your motors. This Official Arduino Motor Shield fits right on top of your Arduino Uno (or compatible) microcontroller and uses a full-bridge L298 driver. The L298 driver is capable of providing 2 channels with 5-12V at 2 amps per channel (or 4 amps max with external power supply) to control inductive loads such as relays, solenoids, and DC or stepper motors. It's perfect for robotics because it is able to control the speed and direction of two DC motors independently, as well as measure the current each motor is using. This means that you can use your motors as an input device by measuring changes in current flow. Did your robot just hit a wall? With the right programming, your Arduino will sense the sudden rise of current from the stalled motors and command your robot to reverse to safety. The shield also features braking so you can stop your robot quickly should the need arise.

Because the Arduino Motor Shield draws a lot of power it must be hooked up to an external 7 - 12V power supply rather than a USB connection to avoid damage. If your motors require more than 9V it is recommended that the power supply lines for the Arduino and the Motor Shield be separated and the "Vin Connect" jumper on the back of the board be cut.

Note: Standard servos will not work on this board.

Features
  • Operating Voltage 5V to 12V
  • Motor controller L298P, Drives 2 DC motors or 1 stepper motor
  • Max current 2A per channel or 4A max (with external power supply)
  • Current sensing 1.65V/A
  • Free running stop and brake function
