Questions

What parts does the IsoPCB use?

25 parts, built around the MEJ2D1212SC, MIC5225YM5-TR, MIC5225-3.3YM5-TR and MIC5271YM5-TR. 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 IsoPCB KiCad files?

From the etti-F/IsoPCB repository on GitHub, at the commit this page was made from: the board is IsoPCB/IsoPCB.kicad_pcb and its schematic IsoPCB/IsoPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the IsoPCB design in my own project?

Its repository states no licence, so its author keeps all rights: ask etti-F before reusing the design.
