Questions
How big is the ButtonMatrixBoard panelized PCB?
It measures 80 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ButtonMatrixBoard panelized use?
104 parts, built around the 1N4148WS 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 ButtonMatrixBoard panelized KiCad files?
From the 8-Lambda-8/ShowControllPCBs repository on GitHub, at the commit this page was made from: the board is buttonMatrixBoard/buttonMatrixBoard_panelized.kicad_pcb and its schematic CAT_XLR/CAT_XLR.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ButtonMatrixBoard panelized 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).
