Questions
How big is the Mini EVSE PCB?
It measures 70 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mini EVSE use?
33 parts, built around the ATTINY84-20PU, IRM-03-5, TMR 1-0522 and SI8261BAC-C-IP. 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 Mini EVSE KiCad files?
From the HuntieDK/Mini-EVSE repository on GitHub, at the commit this page was made from: the board is Mini EVSE.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mini EVSE 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).
