MegaMoto デュアルチャンネル Hブリッジモータコントローラ (Arduino用、13A、5～28V)

Stacked two of these on the Arduino to drive two Treadmill motors (each rated for 130VDC and 18A). The motors are mounted beneath a piece of plywood and along with a front caster we have created a nice little Arduino controlled 2WD cart. My students are learning how to program this "RoboCart". Using two UPS batteries (12V DC for each motor) we are able to drive the cart around. We are using one shield per motor so we can forward or reverse the motors to drive the cart forward, backward, and do circles. We have not started testing with braking code yet but the H bridges have yet to get warm during our routine testing and at only 12V DC we got more than enough speed out of the motors without pushing the shield too hard. The real test will come when we brake the cart to a stop rather than coast. The downloaded documents are excellent and made connecting and using these shields very easy.

Appears to work as advertised! Have not had an opportunity to run with it under load yet? And even then it will only see about 60W tops. they're always pushing you to review products before you have an opportunity to run them through their paces...

Robust, reliable and easy use shield. Comes with a user manual which is very helpful. The speed and direction of each shield is easily controlled by two digital pins of the arduino board.
