Questions
How big is the Clock PCB?
It measures 120 × 120 mm and has 2 copper layers, 1 mm thick.
What parts does the Clock use?
409 parts, built around the XL-1010RGBC-2812B. 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 Clock KiCad files?
From the evansj/ESP32-LED repository on GitHub, at the commit this page was made from: the board is PCB/Clock/Clock.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Clock 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).
