Questions
How big is the WordclockSpacer PCB?
It measures 320.5 × 91 mm and has 2 copper layers, 1.6 mm thick.
What parts does the WordclockSpacer use?
151 parts, built around the ESP-12E, 74HCT1G125GW, 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 WordclockSpacer KiCad files?
From the C3MA/WordclockSpacer repository on GitHub, at the commit this page was made from: the board is WordclockSpacer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the WordclockSpacer design in my own project?
Its repository states no licence, so its author keeps all rights: ask C3MA before reusing the design.
