Questions
How big is the Wordclock PCB?
It measures 60 × 22 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wordclock use?
24 parts, built around the ESP-12E and BSS138. 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 Wordclock KiCad files?
From the bitlair/wordclock repository on GitHub, at the commit this page was made from: the board is pcb/wordclock.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wordclock design in my own project?
Its repository states no licence, so its author keeps all rights: ask bitlair before reusing the design.
