Questions
How big is the Module PCB?
It measures 44.4 × 52.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Module use?
28 parts, built around the AMS1117-1.5, AMS1117-3.3, SN74HC595PWRE4 and TBD62783AFNG,EL. 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 Module KiCad files?
From the GraniteGobbler/VFDClock repository on GitHub, at the commit this page was made from: the board is module_pcb/Module.kicad_pcb and its schematic module_pcb/Module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Module design in my own project?
Its repository states no licence, so its author keeps all rights: ask GraniteGobbler before reusing the design.
