Questions
How big is the NixieDualMod PCB?
It measures 64 × 57.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the NixieDualMod use?
29 parts, built around the SN75468D and 74HC238D. 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 NixieDualMod KiCad files?
From the kevinkessler/NixieClock repository on GitHub, at the commit this page was made from: the board is pcbs/NixieDualModule/NixieDualMod.kicad_pcb and its schematic pcbs/NixieController/NixieController.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the NixieDualMod design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
