Motor Driver Shield Ardumoto presentation

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 blue and yellow 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.

Jumpers and connectors are not included with this product. Don't forget to include shield stacking headers for Arduino with your purchase.

Note: The VIN connection is tied directly to the VIN on the Arduino board, so make sure to not apply power to both.
