Working with the project
Open the .kicad_pro file in KiCad. 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.
Repository notes
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.

Questions
How big is the Spha gateway PCB?
It measures 68 × 87 mm and has 4 copper layers, 4.69 mm thick.
What parts does the Spha gateway use?
75 parts, built around the SN65HVD230D, 74LVC1G07SE-7-MS, LM2594M-5.0 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.
Where can I download the Spha gateway KiCad files?
From the sillevl/spha-gateway-hardware repository on GitHub, at the commit this page was made from: the board is spha-gateway.kicad_pcb and its schematic CAN.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Spha gateway design in my own project?
Its repository states no licence, so its author keeps all rights: ask sillevl before reusing the design.
