Questions
How big is the Lixie clock PCB?
It measures 186.5 × 50.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lixie clock use?
84 parts, built around the ESP32-S2-SOLO-N8, AMS1117-3.3 and WS2812B. 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 Lixie clock KiCad files?
From the rmd6502/lixie_clock repository on GitHub, at the commit this page was made from: the board is lixie clock.kicad_pcb and its schematic digit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lixie clock 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).
