Questions
What parts does the Lighthouse use?
67 parts, built around the TPS62175DQC, PA12 and BC846. 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 Lighthouse KiCad files?
From the MG-5/lighthouse_led_pcb repository on GitHub, at the commit this page was made from: the board is lighthouse.kicad_pcb and its schematic lighthouse.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lighthouse 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).
