Questions
How big is the Card PCB?
It measures 89 × 51 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Card use?
22 parts, built around the MTCH6102-I/MV. 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 Card KiCad files?
From the object1037/Card repository on GitHub, at the commit this page was made from: the board is hardware/card.kicad_pcb and its schematic hardware/card.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Card design in my own project?
Its repository states no licence, so its author keeps all rights: ask object1037 before reusing the design.
