Questions
How big is the RotPad PCB?
It measures 111.1 × 104.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RotPad use?
68 parts, built around the ATMEGA32U4, PRTR5V0U2X and WS2812B. 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 RotPad KiCad files?
From the Gizzzle/RotPad-Macropad repository on GitHub, at the commit this page was made from: the board is KICAD/RotPad.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the RotPad design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
