Questions
How big is the Cypher PCB?
It measures 370.1 × 106 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cypher use?
324 parts, built around the WS2812B, ASMD1206-050, BAT54T1G and MLB3216-600P4A(F). 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 Cypher KiCad files?
From the westfoxtrot/cypher_pcb repository on GitHub, at the commit this page was made from: the board is cypher.kicad_pcb and its schematic cypher.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cypher design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
