I was checking out Texas Instruments offerings in terms of stepper driver IC's and I noticed that they have a booster pack using their DRV8711. It attaches to one of their LaunchPad prototyping platforms to create an 8-52V 4.5Amp max stepper driver. Just wondering if anyone has tried to make their own stepper driver using this. Here is a link to it:
