Questions
What parts does the Rtc pcb use?
10 parts, built around the DS18B20Z, AT24CS02-SSHM-B and DS1307Z+. 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 Rtc pcb KiCad files?
From the arpandebnath56/RTC-PCB-Design repository on GitHub, at the commit this page was made from: the board is rtc_pcb.kicad_pcb and its schematic rtc_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rtc pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask arpandebnath56 before reusing the design.
