Questions
How big is the Buisness Card PCB?
It measures 100.7 × 62.9 mm and has 2 copper layers, 1.2 mm thick.
What parts does the Buisness Card use?
35 parts, built around the ATTINY85-20SU and MBR0520L-TP. 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 KenwoodFox/ProtoCard repository on GitHub, at the commit this page was made from: the board is Hardware/Buisness Card/Buisness Card.kicad_pcb and its schematic Hardware/Buisness Card/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 states no licence, so its author keeps all rights: ask KenwoodFox before reusing the design.
