This is going to be a pretty slick board - just a bare bones simple stepper motor driver board. I love using these fully integrated drivers - they take care of everything for you. A couple pins from your microcontroller enable the driver, set the direction, and actually step the motor. I'll be doing videos on how to use the DRV8825 (using this board), position and speed control, and a couple other cool things. In the mean time, check out the wiki page: http://www.kevindarrah.com/wiki/index.php?title=Stepper_Board
Side note, I just started working on something that might be the coolest thing I've ever done with the ESP8266 WiFi module... I think we know what the next board will be based on. But anyway, these Stepper boards should be here soon and I'll get them out to the bare board members asap. I may ship them with the driver populated too, we'll see.
