Questions
How big is the Isolator PCB?
It measures 33 × 67.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Isolator use?
43 parts, built around the ISO6741DW and ISO6721BD. 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 Isolator KiCad files?
From the SG-O/Isolator repository on GitHub, at the commit this page was made from: the board is Isolator.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Isolator 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).
