The Ardumoto is a motor shield for Arduino that will control two DC motors. Based on the L298 H-bridge, Ardumoto can drive up to 2 Amps per channel. The board takes its power from the same Vin line as the Arduino board. Blue and yellow LEDs indicate active direction. All driver lines are diode protected from back EMF.

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).

Connectors not included

Note: This board does not ship with any connectors for Arduino or motors. See the options below to add connectors that you can solder to the board to suit your design. The lower image shows an example of what the Ardumoto will look like with the Stackable Header Kit and a pair of 2-pole 3.5mm screw terminals installed, and what it will look like mated to an Arduino board. The board also has pads for external VIN (Max 18V) via header pins or a third 2-pole screw terminal.
