ULN2003 and stepper motor 5V

This is the cheapest combination of stepper motor and controller i could get mi hands on, through ebay(2.92$ with shipping).

First impressions for this set is that you get what you pay for. The ULN2003AN is a Texas Instruments DIP chip. Circuitboard measures 32mm in width and 35mm in length. Chip is seated on a socket so if there are any complications, as in the magic white smoke leaking out, you can replace the chip. All of the board is a full through hole design so again if anything misbehaves just replace it. Soldering job is adequate for this kind of cheap-o standard. One solderbridge but that's the only thing that's amiss.

The Stepper motor supplied has the markings a 28BYJ-48, so it has 4 phases 8 beats. With internal gearing in 1:64. It's rated at 5V DC. Motor-s diameter is 28mm. And is supplied with 20cm wires.On the sides it has two mounting holes for screws, rivets or anything else you can think of for mounting.
