Questions
How big is the ClockIOT PCB?
It measures 162.6 × 194.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ClockIOT use?
289 parts, built around the CP2102N-A01-GQFN28R, ESP-WROOM-32D, DS3231N/DIP and DDC114TU. 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 ClockIOT KiCad files?
From the wyolum/ClockIOT repository on GitHub, at the commit this page was made from: the board is kicad/kicad_old_versions/kicad_v1/ClockIOT.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ClockIOT 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).
