Questions
How big is the RTC append PCB?
It measures 89.9 × 127.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RTC append use?
104 parts, built around the 24C16 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 append KiCad files?
From the ExploreEmbedded/EEPROM-and-RTC-Breakout-Board repository on GitHub, at the commit this page was made from: the board is Hardware Design/RTC-append.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the RTC append design in my own project?
Its repository states no licence, so its author keeps all rights: ask ExploreEmbedded before reusing the design.
