Questions
How big is the TokenBoard PCB?
It measures 353.7 × 129.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the TokenBoard use?
422 parts, built around the 74AHCT1G125SE, ME6211C33M5G-N, 1N4148W and SK6812MINI-E. 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 TokenBoard KiCad files?
From the h3ll5ur7er/TokenBoard repository on GitHub, at the commit this page was made from: the board is kb/kb.kicad_pcb and its schematic kb/kb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TokenBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask h3ll5ur7er before reusing the design.
