I am currently trying to design a model railway turntable so that I can simply select an outgoing road and the turntable will consistently rotate and line up to outgoing tracks. I have purchased an Arduino Uno and am having fun relearning programming!

The motor I am looking at seems suitable in that it has 400 steps per rotation and a 5mm shaft to match the base of the turntable.

However I note that it is rated at 3v and 1.7A. As the Big Easy Board needs at least 7v to operate will it harm board or motor if I apply a 12v supply (basic voltage on the model railway)?

Whilst I am OK programming I am a bit lacking in my electronics knowledge! Any guidance would be appreciated.
