Questions
How big is the ELECA PCB?
It measures 86 × 54 mm and has 2 copper layers, 0.69 mm thick.
What parts does the ELECA use?
71 parts, built around the ESP32-C3-MINI-1-H4, XC6220B331MR, SK9822-EC20 and IN-S63ASR. 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 ELECA KiCad files?
From the lightcafe-lab/ELECA repository on GitHub, at the commit this page was made from: the board is pcb/pcb-eleca/ELECA.kicad_pcb and its schematic pcb/pcb-eleca-extend/eleca-extend.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ELECA design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
