Questions

What parts does the Layouts use?

3 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 Layouts KiCad files?

From the jrhrsmit/ato-packages repository on GitHub, at the commit this page was made from: the board is packages/opamp_hysteresis/layouts/default/default.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Layouts 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).
