Questions
How big is the OpenNixie PCB?
It measures 152 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the OpenNixie use?
74 parts, built around the MAX1771CSA+T, 74HC595, AMS1117 and DS3231MZ+. 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 OpenNixie KiCad files?
From the bclswl0827/OpenNixie repository on GitHub, at the commit this page was made from: the board is circuit/motherboard/OpenNixie.kicad_pcb and its schematic circuit/holder/IN-12/IN-12.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the OpenNixie design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
