Questions
How big is the VFD Clock PCB?
It measures 200 × 50 mm and has 4 copper layers, 1.6 mm thick.
What parts does the VFD Clock use?
486 parts, built around the 74VHC541D, MCP9804-E/MC, TPS62130RGT and 74LVC1G97GV. 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 VFD Clock KiCad files?
From the drewsum/VFD_Clock repository on GitHub, at the commit this page was made from: the board is rev_a/hdw/Logic_Board/VFD_Clock/VFD_Clock.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the VFD Clock design in my own project?
Its repository states no licence, so its author keeps all rights: ask drewsum before reusing the design.
