Help selecting a motor controller

I am not at all experienced with motors and controllers, so I need some help. I need to select a motor controller for use with my Pololu 37D motor. I am running a carriage on a belt-driven guide rail, and the carriage must go both forwards and backwards. I have limit switches to mount on the guide rail that will need to connect to the controller. What do I need for this process, I know almost nothing about the subject. Thanks

Hi.

You might consider our Pololu Simple Motor Controller 18v7. Any of the unused analog channels on this controller can be used with limit switches.
