Yet another stepper driver
YetAnotherStepperDriver is a breakout board for the DRV8825 stepper motor controller IC. The IC can put out 3A of current, so proper cooling is a must. This is the reason behind so many vias around the bottom pad of the IC.

These modules are designed to connect to a booster pack i have yet to design for a Stellaris Launchpad ( overkill? perhaps..) via the FFC on the left side of the board. The motor would be powered by 12V from a computer PSU via the screw terminals on the bottom. I tried to stay away from .1″ pins for the most part. I took inspiration from bearmos’ cnc controller with the thermal vias.
