Questions
How big is the Clackpad PCB?
It measures 78.6 × 61.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Clackpad use?
25 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 Clackpad KiCad files?
From the opticaldrive/clackpad repository on GitHub, at the commit this page was made from: the board is PCB/Clackpad.kicad_pcb and its schematic PCB/Clackpad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Clackpad 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).
