I was only able to get this motor shield working once I paired it up with an arduino uno. It was pretty easy after that to make it work to drive 4 solenoid valves. I wanted to use it with another brand of microcontroller but was unable to which is why I am taking one star off. Otherwise it has been pretty useful, making it a 4/5 stars for me.

Arrived with pins bent, but i managed to bend it back. The shield also doesnt fit all the way down into the arduino board, theres about a 1mm gap. Still works, but that might bother some people if not enclosed in a case. I found that even when using a 12v external power adapter, attached motors might be underpowered.Worse part is the noise. When connected to power, it has a very audible humm. This is before connecting anything to the shield. Recommend to look for more modern shields, especially if you are bothered by the humm

I tested this when I got it and all was well. I hooked two 5v DC motors up to it and got some Arduino code and had fun making the motors do different things.I pulled the yellow jumper so I could power the Arduino separately from this motor driver. To power this driver I had an AC-DC converter that goes to an electronic device I no longer use, it outputs 12 V DC which was plenty for the motors I was playing with (I cut the connector off the converter and used solder on the stranded wire to make strong connectors I could push into the PWR_IN port on the card)Pay attention to the 600 mA max draw, I figured a couple of steps from a 1.6 A stepper motor wouldn't hurt anything to make sure some new steppers I bought worked. Even just a couple of steps (literally milliseconds) got the chips on this card very hot! The card survived just fine though, but, umm, don't do that. (search Amazon for L298N if you want to test steppers up to 2A)So it works great and even survived some abuse at a great price.
