Questions
How big is the Epaper PCB?
It measures 65 × 30 mm and has 2 copper layers, 1 mm thick.
What parts does the Epaper use?
56 parts, built around the CP2102N-A01-GQFN28R, ESP32-WROOM-32D, TC8002D and AMS1117-3.3. 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 Epaper KiCad files?
From the TDA-2030/E-ink-screen repository on GitHub, at the commit this page was made from: the board is hardware/epaper.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Epaper design in my own project?
Its repository publishes it under the Apache-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).
