Questions

How big is the Buisness Card PCB?

It measures 89 × 50 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Buisness Card use?

23 parts, built around the NT3H2111W0FTTJ. 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 Buisness Card KiCad files?

From the Ayarfox/BusinessCard repository on GitHub, at the commit this page was made from: the board is Buisness_Card.kicad_pcb and its schematic Buisness_Card.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Buisness 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).
