Questions
How big is the Bugg mic r4 PCB?
It measures 30.5 × 22 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Bugg mic r4 use?
25 parts, built around the SPH0641LU4H-1. 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 Bugg mic r4 KiCad files?
From the bugg-resources/bugg-hardware-mic repository on GitHub, at the commit this page was made from: the board is r4/src/bugg-mic-r4.kicad_pcb and its schematic r1/src/safeproject-mic-r1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bugg mic r4 design in my own project?
Its repository states no licence, so its author keeps all rights: ask bugg-resources before reusing the design.
