Questions
How big is the Isolation Board PCB?
It measures 90 × 50 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Isolation Board use?
29 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 Isolation Board KiCad files?
From the MECSEM/electrical repository on GitHub, at the commit this page was made from: the board is LV-Misc/Isolation Board/Isolation Board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Isolation Board 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).
