The Motor Shield is a perfect platform for robotics and mechanical applications. It enables the Arduino to drive two brushed DC motors or one 4-wire two-phase stepper motor. Based on the H-bridge driver Chip L298N motor driver integrated circuit, it requires a 6V to 15V power supply to power the motor and also includes an on-board 5V voltage regulator for powering the main Arduino board. Additional plug and play Grove sensors can be connected to the 13 on-board Grove connectors.
I used this for a small robot that was later disassembled and don't need this anymore. Works.
I have a number of other computer parts, electronics and test equipment listed right now, so if you're interested, check out my other auctions.
I ship within 2 business days of receipt of payment. Good luck, and thanks for bidding!
