Questions
How big is the Ring pcb PCB?
It measures 17.8 × 17.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ring pcb use?
18 parts. 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 KiCad files?
From the whatnick/lantern_ring repository on GitHub, at the commit this page was made from: the board is hardware/v1.0/ring_pcb/ring_pcb.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 design in my own project?
Its repository states no licence, so its author keeps all rights: ask whatnick before reusing the design.
