From the project

My dumping grounds for all my kicad projects and random hardware bringup.

NOTE FOR PULL REQUESTS: I DO NOT ACCEPT MASS ADDS. If you have 5-6 really awesome parts, I'll accept a pull request, but if you have say 10+ parts, I will not. Select only the neatest. Also, make sure JLCPCB offers the parts, if they're intended for board mounting!
