Questions
How big is the Nixie driver PCB?
It measures 50 × 80 mm and has 2 copper layers, 1.58 mm thick.
What parts does the Nixie driver use?
17 parts, built around the HCF4094BE and IN-12B. 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 Nixie driver KiCad files?
From the Quettle/nixie_driver repository on GitHub, at the commit this page was made from: the board is nixie_driver.kicad_pcb and its schematic nixie_driver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nixie driver design in my own project?
Its repository states no licence, so its author keeps all rights: ask Quettle before reusing the design.
