Questions
What parts does the Eink watch use?
18 parts, built around the MBR0530 and SI1308EDL. 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 Eink watch KiCad files?
From the devramsean0/eink-watch repository on GitHub, at the commit this page was made from: the board is board/board.kicad_pcb and its schematic board/board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Eink watch 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).
