The Sparkfun Ardumoto shield for Arduino 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 and includes blue and yellow LEDs to indicate active direction. All driver lines are diode protected from back EMF. The L298 is a two-channel motor driver making it perfect for a two-wheel-drive vehicle. Each channel on the L298 can deliver up to 2A to the motor to which it’s connected. Keep in mind, though, that the amount of current available to your motor also depends on your system’s power source. This is a great motor driver for a Max or Rex mobile robot base.
Part does require some soldering.
The VIN connection is tied directly to the VIN on the Arduino, so make sure to not apply power to both.
We will solder the Arduino headers onto the board for a small fee. (Options)
