DFRobot DRI0009 Motor Shield for Arduino, 2A

Works great on my tank robot.

It's good and did what it was supposed to. Just I tried using PLL and PWM both to power a 12 V and also a 1.5 V motor and it wouldn't work when powered through the arduino. It needed to have separate power and then it worked fine. Only took a few hours of wonder why to get that figured out. Just making sure common ground for both the arduino and the shield are very important. A friend ordered the exact same shield and it was DOA however and it was a time related issue. So it wasn't feasible to get another in the time needed.

These worked perfectly for our student labs. Thank you!

Works well for small projects (especially those requiring around 2 amps)

Mi único problema fue el detalle en los pin, al conectarla a un arduino y luego retirarlo después de su uso ocasionaba que se doblaran los pin.Hay que tener cuidado.
