Questions
How big is the TimerClock PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TimerClock use?
33 parts, built around the ATMEGA328P-PU, CD4511BE, DS1307+ and OS102011MS2QN1. 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 TimerClock KiCad files?
From the kseebaldt/clock_rtc repository on GitHub, at the commit this page was made from: the board is kicad/TimerClock/TimerClock.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the TimerClock design in my own project?
Its repository states no licence, so its author keeps all rights: ask kseebaldt before reusing the design.
