Questions
How big is the STM32 Nixie PCB?
It measures 154 × 57 mm and has 4 copper layers, 1.6 mm thick.
What parts does the STM32 Nixie use?
196 parts, built around the BS-7. 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 STM32 Nixie KiCad files?
From the arjunven/STM32_Nixie repository on GitHub, at the commit this page was made from: the board is pcb/STM32_Nixie.kicad_pcb and its schematic pcb/STM32_Nixie.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32 Nixie design in my own project?
Its repository states no licence, so its author keeps all rights: ask arjunven before reusing the design.
