Questions
How big is the OctaveKeyboardPCB PCB?
It measures 161 × 77 mm and has 2 copper layers, 1.6 mm thick.
What parts does the OctaveKeyboardPCB use?
50 parts, built around the 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 OctaveKeyboardPCB KiCad files?
From the Barbatronic/ModularKeytar repository on GitHub, at the commit this page was made from: the board is ECAD/OctaveKeyboardPCB/OctaveKeyboardPCB.kicad_pcb and its schematic ECAD/OctaveKeyboardPCB/OctaveKeyboardPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the OctaveKeyboardPCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask Barbatronic before reusing the design.
