Questions
How big is the MacroKeyPadV2 PCB?
It measures 108 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MacroKeyPadV2 use?
30 parts, built around the XL-2020RGBC-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 MacroKeyPadV2 KiCad files?
From the 9elements/MacroGadget repository on GitHub, at the commit this page was made from: the board is MacroKeyPadV2/MacroKeyPadV2.kicad_pcb and its schematic MacroKeyPad/MacroKeyPad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MacroKeyPadV2 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).
