Man, don't you just hate how so many devices are wired instead of wireless? Well, I sure do.
Unwired is a project that aims to take a USB peripheral (like a mouse/keyboard) and allow you to connect to it wirelessly while simultaniously being as compact as possible because wired stuff can be pretty annoying at times

Questions
How big is the Unwired PCB?
It measures 29.4 × 61.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Unwired use?
90 parts, built around the TPD6S300ARUK and TVS2200DRV. 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 Unwired KiCad files?
From the NoxAevi/Unwired repository on GitHub, at the commit this page was made from: the board is PCB/Unwired/Unwired.kicad_pcb and its schematic PCB/Unwired/Unwired.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Unwired design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
