Questions
How big is the DMClock PCB?
It measures 168.3 × 120.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DMClock use?
204 parts, built around the HV5622PG-G, DS3231SN#T&R, 2SC1815 and CPT-1255C-090. 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 DMClock KiCad files?
From the danielpchamoun/DMClock repository on GitHub, at the commit this page was made from: the board is DMClock/DMClock.kicad_pcb and its schematic DMClock/DMClock.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DMClock design in my own project?
Its repository states no licence, so its author keeps all rights: ask danielpchamoun before reusing the design.
