Questions
How big is the Name card PCB?
It measures 85.6 × 54 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Name card use?
16 parts, built around the ATTINY25V-10SU and ST25DV64K-JFR6D3. 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 Name card KiCad files?
From the Nicholas1023/name-card repository on GitHub, at the commit this page was made from: the board is src/name-card.kicad_pcb and its schematic src/name-card.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Name card 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).
