Questions
How big is the Lightup namebadge PCB?
It measures 100 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lightup namebadge use?
26 parts. 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 Lightup namebadge KiCad files?
From the headblockhead/lightup-namebadge repository on GitHub, at the commit this page was made from: the board is lightup-namebadge.kicad_pcb and its schematic lightup-namebadge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lightup namebadge design in my own project?
Its repository states no licence, so its author keeps all rights: ask headblockhead before reusing the design.
