Questions
How big is the DCF77-RTC PCB?
It measures 78.9 × 30.4 mm and has 4 copper layers, 4.69 mm thick.
What parts does the DCF77-RTC use?
31 parts, built around the ATTINY88-PU, IRLML6402, BC847 and DS3231S#. 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 DCF77-RTC KiCad files?
From the DoImant/DCF77-RTC-PCB repository on GitHub, at the commit this page was made from: the board is DCF77-RTC.kicad_pcb and its schematic DCF77-RTC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DCF77-RTC design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
