I spent some of last night laying out the first rev of the board for this project - you can check it out now in the Github repo if you like.

Even if the board comes back and is functional, I will probably do a second run with more of an eye to the ergonomics - I need to figure out exactly how I'd like to use this, how it should feel in my hand, and whether or not to add extra buttons (ie, toggle the stepper's "enable" pin to allow it to be manually moved, allow inputs for limit switches, and provide an optional header for more common OLED screens)

I'm not looking to make this a very generic controller - it's pretty specifically a one-channel jog for CNC devices. That said, let me know if I'm missing a crucial feature, it'd be nice ot hear what you think!
