Questions
What parts does the Core sf use?
114 parts, built around the 10M02SCE144I7G, MAX485ED, SN65HVD230D and AMS1117-3.3. 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 sf KiCad files?
From the krtkr/4hbd repository on GitHub, at the commit this page was made from: the board is core_sf/core_sf.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Core sf design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
