Questions
How big is the ESP32-Eink PCB?
It measures 59.2 × 29.2 mm and has 4 copper layers, 1.86 mm thick.
What parts does the ESP32-Eink use?
83 parts, built around the ESP32-C3, TPS63001DRC, BQ24074RGTR and USBLC6-2SC6. 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 ESP32-Eink KiCad files?
From the Outdatedcandy92/ESP32-Eink repository on GitHub, at the commit this page was made from: the board is pcb/ESP32-EINK.kicad_pcb and its schematic pcb/ESP32-EINK.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32-Eink design in my own project?
Its repository publishes it under the CERN-OHL-W-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).
