Questions
How big is the Usb isolator PCB?
It measures 50 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Usb isolator use?
39 parts, built around the NUP4202W1 and ADUM4160BRW. 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 isolator KiCad files?
From the dfro/usb_isolator repository on GitHub, at the commit this page was made from: the board is usb_isolator.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usb isolator design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
