Description
This is a motor shield for Arduino board 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, includes LEDs to indicate active direction, and all driver lines are diode protected from back EMF. 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.
The following view shows the main components of the Motor Driver Shield Ardumoto.
Control for motor attached to OUT1/2 is connected to digital line 12 (direction A) and digital line 3 (PWM A). Control for motor attached to OUT3/4 is connected to digital line 13 (direction B) and digital line 11 (PWM B).
Note: The VIN connection is tied directly to the VIN on the Arduino board, so make sure to not apply power to both.

Note:
The Ardumoto Shield does not come with the 4 x through headers soldered to the board.
