Questions

How big is the ProMicro LOG PCB?

It measures 17.8 × 30.5 mm and has 2 copper layers, 0.8 mm thick.

What parts does the ProMicro LOG use?

16 parts, built around the DS3231MZ/V+. 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 ProMicro LOG KiCad files?

From the clayton13/ProMicro repository on GitHub, at the commit this page was made from: the board is LOG/ProMicro_LOG.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the ProMicro LOG design in my own project?

Its repository states no licence, so its author keeps all rights: ask clayton13 before reusing the design.
