Questions
How big is the Example PCB?
It measures 43.2 × 35.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Example use?
12 parts, built around the LDC1314. 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 Example KiCad files?
From the eliassjogreen/inductive-analog-switch repository on GitHub, at the commit this page was made from: the board is example/example.kicad_pcb and its schematic example/example.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Example design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
