Questions
How big is the Esp32s3-ducky epaper PCB?
It measures 34.8 × 65.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32s3-ducky epaper use?
98 parts, built around the ESP32-S3, W25Q128JVSIQ, AMS1117-3.3 and SS14. 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 Esp32s3-ducky epaper KiCad files?
From the rompasaurus/dilder repository on GitHub, at the commit this page was made from: the board is hardware-design/reference-boards/esp32s3-ducky-epaper/hardware.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32s3-ducky epaper design in my own project?
Its repository states no licence, so its author keeps all rights: ask rompasaurus before reusing the design.
