Questions
How big is the Core PCB?
It measures 44.8 × 72.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Core use?
66 parts, built around the USBLC6-4SC6, BSS138 and MF-MSMF110-2. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Core KiCad files?
From the SL-RU/osfi-p repository on GitHub, at the commit this page was made from: the board is sch/core/core.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Core design in my own project?
Its repository states no licence, so its author keeps all rights: ask SL-RU before reusing the design.
