Questions
How big is the StudioClock PCB?
It measures 152 × 94.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the StudioClock use?
27 parts, built around the MAX7219M, MAX333CWP+ and IRF540N. 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 StudioClock KiCad files?
From the quinot/StudioClock repository on GitHub, at the commit this page was made from: the board is studioclock.kicad_pcb and its schematic clockface/clockface.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the StudioClock design in my own project?
Its repository states no licence, so its author keeps all rights: ask quinot before reusing the design.
