Questions
How big is the Cccamp23 nametag PCB?
It measures 85 × 53 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cccamp23 nametag use?
34 parts, built around the ATTINY402-SSN, WS2812B-MINI-X2 and MMBT3904. 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 Cccamp23 nametag KiCad files?
From the HazeCore/Nametag_Hardware repository on GitHub, at the commit this page was made from: the board is cccamp23_nametag.kicad_pcb and its schematic cccamp23_nametag.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cccamp23 nametag design in my own project?
Its repository states no licence, so its author keeps all rights: ask HazeCore before reusing the design.
