Questions
How big is the Clock mod PCB?
It measures 37.5 × 110 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Clock mod use?
78 parts, built around the LM1117MP-5.0, MMBT3904 and SS14. 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 mod KiCad files?
From the Se64s/clock-mod repository on GitHub, at the commit this page was made from: the board is pcb/clock-mod.kicad_pcb and its schematic panel/clock-mode-panel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Clock mod 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).
