Questions
How big is the Clocker-12b PCB?
It measures 39.6 × 110.9 mm and has 16 copper layers, 1.6 mm thick.
What parts does the Clocker-12b use?
84 parts, built around the ATMEGA328-PU, TL072, PJ301M-12 and BAT54S. 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 Clocker-12b KiCad files?
From the 4ms/pcb-RCD-SCM-clocker repository on GitHub, at the commit this page was made from: the board is pcb-v1.2/kicad/clocker-12b.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Clocker-12b design in my own project?
Its repository states no licence, so its author keeps all rights: ask 4ms before reusing the design.
