Questions
How big is the CAT XLR PCB?
It measures 46 × 120 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CAT XLR use?
26 parts. 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 CAT XLR KiCad files?
From the 8-Lambda-8/ShowControllPCBs repository on GitHub, at the commit this page was made from: the board is CAT_XLR/CAT_XLR.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 CAT XLR 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).
