So, I finally have a first draft of the PCB for the keyboard I want to make. I’ve put it on GitHub: https://github.com/joelproko/keyboard_layout_jopr
A few questions:
- I’ve never done this before, so I expect there to be mistakes, but don’t hesitate to point them out. Like maybe it’s a bad idea to have the USB data lines so close to the edge?
- The USB Multex has connections labeled 2 and 6, which aren’t connected. 2 because it was like that in the guide, 6 because it didn’t exist in the version of the footprint the guide maker used. What are they for and what do I do with them?
- When I run Kicad’s design rules check, it complains something about an incorrect courtyard for the USB Multex, and about holes drilled too close to eachother for every single key footprint. Can I ignore these warnings? If not, how do I fix it?
- There’s no pins left for the lock status LEDs (there’s one left, but it’s labeled AREF in the schematic, so I guess it’s special). Which controller would you recommend instead?
