Questions
How big is the Ring pcb dotstar PCB?
It measures 19.1 × 19 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ring pcb dotstar use?
2 parts, built around the ATTINY85V-10MU. 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 Ring pcb dotstar KiCad files?
From the whatnick/lantern_ring repository on GitHub, at the commit this page was made from: the board is hardware/v2.0/ring_pcb_dotstar/ring_pcb_dotstar.kicad_pcb and its schematic hardware/v1.0/ring_pcb/ring_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ring pcb dotstar design in my own project?
Its repository states no licence, so its author keeps all rights: ask whatnick before reusing the design.
