Questions

How big is the Control module PCB?

It measures 96 × 38 mm and has 2 copper layers, 1 mm thick.

What parts does the Control module use?

74 parts, built around the DS3231MZ/V+, BAT54, BAT240A and BSS84. 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 Control module KiCad files?

From the gabebuckmaster/nixie_clock repository on GitHub, at the commit this page was made from: the board is electronics/control_module/control_module.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Control module 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).
