Questions
How big is the IButton PCB?
It measures 15.8 × 24.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the IButton use?
29 parts, built around the TSOP75338TR, VSMY14940, D5V0H1B2LP-7B and MLT-8530. 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 IButton KiCad files?
From the KarkeNeko/ClipperOne repository on GitHub, at the commit this page was made from: the board is Hardware/iButton/iButton.kicad_pcb and its schematic Hardware/iButton/iButton.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the IButton design in my own project?
Its repository states no licence, so its author keeps all rights: ask KarkeNeko before reusing the design.
