Questions
How big is the Clock module--100mmX100mm PCB?
It measures 56 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Clock module--100mmX100mm use?
35 parts, built around the LM555N, 74LS04PC and 74LS32SC. 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 module--100mmX100mm KiCad files?
From the lelandbatey/clock-module repository on GitHub, at the commit this page was made from: the board is clock-module--100mmX100mm.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Clock module--100mmX100mm design in my own project?
Its repository states no licence, so its author keeps all rights: ask lelandbatey before reusing the design.
