Questions
How big is the NTP Server PCB?
It measures 52 × 36.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the NTP Server use?
10 parts, built around the DS3231MZ/V+ and CR2032. 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 NTP Server KiCad files?
From the Qeteshpony/NTP-Server repository on GitHub, at the commit this page was made from: the board is pcb/NTP-Server.kicad_pcb and its schematic pcb/NTP-Server.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the NTP Server design in my own project?
Its repository publishes it under the BSD-2-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
