Questions
How big is the Rid PCB?
It measures 41 × 41 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rid use?
12 parts, built around the ATTINY1614-SSN. 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 Rid KiCad files?
From the swr06/LED-Wearable repository on GitHub, at the commit this page was made from: the board is V02/KiCad/earring/rid.kicad_pcb and its schematic V02/KiCad/earring/rid.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rid 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).
