Questions
How big is the Eink PCB?
It measures 62.4 × 115 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Eink use?
116 parts, built around the ESP32-S3-WROOM-1-N8, AP3031KTR-G1, TPD4E1U06DBVR and 74LVC1G04Z. 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 KiCad files?
From the gaoDean/eink repository on GitHub, at the commit this page was made from: the board is eink.kicad_pcb and its schematic eink.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Eink design in my own project?
Its repository states no licence, so its author keeps all rights: ask gaoDean before reusing the design.
