Questions
How big is the 1 3S PCB?
It measures 118.5 × 91.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 1 3S use?
46 parts, built around the XIAO NRF52840. 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 1 3S KiCad files?
From the igor-salt/ERGO repository on GitHub, at the commit this page was made from: the board is 1_3/1_3S/1_3S.kicad_pcb and its schematic 1_3/1_3/1_3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 1 3S design in my own project?
Its repository publishes it under the CERN-OHL-P-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).
