A SmoothieBoard has the pins for external driver connections (as do a few other boards that cost a little more).
The driver in your photo looks like one of the problematic TB6600 units. I suggest you look into it.
This is the sort of trouble you can run into when you search for and buy the cheapest of everything. Now, unless you go to the expense of replacing all the stuff you bought, you have several hours of work to do to get it all working together. If and when you get it working, how long will it keep working and how much trouble will it be to fix problems? Did you really save that much money?
