Questions
How big is the Nametag proj PCB?
It measures 70 × 70 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Nametag proj use?
88 parts, built around the ATMEGA32U4RC-MU, DW01A, TP4056-42-ESOP8 and TPS63031DSK. 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 Nametag proj KiCad files?
From the Morgenrot-dev/nametag-pcb repository on GitHub, at the commit this page was made from: the board is nametag_proj.kicad_pcb and its schematic nametag_proj.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nametag proj design in my own project?
Its repository states no licence, so its author keeps all rights: ask Morgenrot-dev before reusing the design.
