Questions
How big is the Cynaroides PCB?
It measures 145.3 × 115.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Cynaroides use?
136 parts, built around the USBLC6-2SC6, 1N4148W, SK6812MINI-E and DTC123JE. 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 Cynaroides KiCad files?
From the vattern/Cynaroides repository on GitHub, at the commit this page was made from: the board is cynaroides.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cynaroides design in my own project?
Its repository states no licence, so its author keeps all rights: ask vattern before reusing the design.
