Questions

How big is the Usb armor PCB?

It measures 28.8 × 28.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Usb armor use?

20 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 armor KiCad files?

From the Squantor/various_PCB repository on GitHub, at the commit this page was made from: the board is electronics/usb_armor/usb_armor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Usb armor 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).
