The design includes files originating from an older KiCad workflow; review schematic links, footprints, design rules, zones, and manufacturing outputs after any conversion or upgrade.
KiCad source files and project-specific libraries are the source of truth. Generated BOM, Gerber, assembly, and fabrication-house outputs are excluded from the repository; regenerate and verify them before manufacturing.
Temporary KiCad state, locks, autosaves, and backup directories are excluded by .gitignore. Board revision, tested KiCad version, manufacturing revision, and hardware/firmware compatibility still need to be recorded when provenance is confirmed.

71 parts, built around the SN65HVD230D, BME280, TPS62175DQC and PESD2CAN. 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.
From the sillevl/spha-btnn-hardware repository on GitHub, at the commit this page was made from: the board is niko-4-6-way-button.kicad_pcb and its schematic niko-4-6-way-button.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask sillevl before reusing the design.
