Questions
How big is the ES3ink PCB?
It measures 60.8 × 31 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ES3ink use?
84 parts, built around the ESP32-S3-WROOM-1-N8, AP2112K-3.3, MBR0530 and AO3401A. 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 ES3ink KiCad files?
From the dronecz/ES3ink repository on GitHub, at the commit this page was made from: the board is HW/ES3ink.kicad_pcb and its schematic HW/ES3ink.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ES3ink design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
