Questions
How big is the Nixie control board PCB?
It measures 200 × 66 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Nixie control board use?
79 parts, built around the ATMEGA328P-AU, MC34063A, TLP521-4 and DS3231S#. 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 control board KiCad files?
From the shengwen-tw/nixie-clock repository on GitHub, at the commit this page was made from: the board is circuit/commertial_design_ver3/control_board/nixie_control_board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nixie control board 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).
