I hope this isn't too noob-ish, but I'm not sure how exactly to use what you have in github to get me a few of these things.

The boards have to be ordered from somewhere, I believe...that's not a home-made pcb. SMD soldering is kinda scary too...not sure if my wife is going to like me baking chips in the oven. So, do you have suggestions/advice on this, or are you going to sell pre-built ones?
