Questions
How big is the UEther PCB?
It measures 36 × 77 mm and has 4 copper layers, 1.57 mm thick.
What parts does the UEther use?
65 parts, built around the 93AA56AT-I/OT, USBLC6-2P6 and B1603S. 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 UEther KiCad files?
From the WebmasterTD/uEther repository on GitHub, at the commit this page was made from: the board is uEther_hw/uEther.kicad_pcb and its schematic uEther_hw/power_filter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the UEther 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).
