Questions
How big is the PolarisPad PCB?
It measures 81 × 61 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PolarisPad use?
23 parts, built around the SK6812MINI-E. 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 PolarisPad KiCad files?
From the PendulumPower/PolarisPad repository on GitHub, at the commit this page was made from: the board is PCB/PolarisPad.kicad_pcb and its schematic PCB/PolarisPad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PolarisPad 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).
