Questions

How big is the USB key PCB PCB?

It measures 12.1 × 28.1 mm and has 4 copper layers, 2 mm thick.

What parts does the USB key PCB use?

28 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 USB key PCB KiCad files?

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

Can I use the USB key PCB 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).
