Questions
How big is the BarePi RTC PCB?
It measures 65 × 48 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BarePi RTC use?
15 parts, built around the AT24C32N 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 BarePi RTC KiCad files?
From the Panda381/BarePi repository on GitHub, at the commit this page was made from: the board is RTC/KiCAD/BarePi_RTC.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BarePi RTC design in my own project?
Its repository states no licence, so its author keeps all rights: ask Panda381 before reusing the design.
