Questions
How big is the Nixie main board PCB?
It measures 127 × 45.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Nixie main board use?
48 parts, built around the ATMEGA328P-PU, MC34063AP, DS3231MZ+ and BC557. 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 main board KiCad files?
From the kevinbchen/nixie-clock repository on GitHub, at the commit this page was made from: the board is nixie_main_board/nixie_main_board.kicad_pcb and its schematic nixie_main_board/nixie_main_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nixie main board design in my own project?
Its repository states no licence, so its author keeps all rights: ask kevinbchen before reusing the design.
