I've almost finished laying out the main board in Kicad. The Freerouting application was a lifesaver here - this would have been a pain to route manually.

Still have to tweak it a bit, double check the netlist, and make layouts for the power bus and sensors. Those will be quick to do. Once I'm done I'll post the Kicad files here and maybe on Github.

I hope to place my PCB order in a week or two. I will have a few extra boards for anyone that is interested.
