Questions
How big is the Dcf77clock v2 PCB?
It measures 147.3 × 61 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dcf77clock v2 use?
35 parts, built around the TBD62783APG and ULN2003A. 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 Dcf77clock v2 KiCad files?
From the achkoe/dcf77clock repository on GitHub, at the commit this page was made from: the board is kicad/dcf77clock_v2.kicad_pcb and its schematic kicad/dcf77clock_v2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dcf77clock v2 design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
