Questions
How big is the Conndom PCB?
It measures 94 × 30 mm and has 2 copper layers, 1.58 mm thick.
What parts does the Conndom use?
18 parts, built around the SK6812. 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 Conndom KiCad files?
From the tmsmr/conndom repository on GitHub, at the commit this page was made from: the board is pcb/conndom.kicad_pcb and its schematic pcb/conndom.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Conndom design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
