Questions
What parts does the RingDemo smallerClearance use?
20 parts, built around the ATTINY85-20SU and WS2812B. 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 RingDemo smallerClearance KiCad files?
From the Laser4DIY/Laser4DIY-Coin repository on GitHub, at the commit this page was made from: the board is kicad-project/ringDemo_smallerClearance.kicad_pcb and its schematic kicad-project/ringDemo.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RingDemo smallerClearance design in my own project?
Its repository states no licence, so its author keeps all rights: ask Laser4DIY before reusing the design.
