Questions

How big is the PCB keychain PCB?

It measures 8.3 × 30 mm and has 2 copper layers, 1.6 mm thick.

What parts does the PCB keychain use?

5 parts. 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 PCB keychain KiCad files?

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

Can I use the PCB keychain design in my own project?

Its repository states no licence, so its author keeps all rights: ask SanaDeghat before reusing the design.
