Questions
How big is the Bug PCB?
It measures 30 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bug use?
53 parts, built around the MAX2606EUT, MAX2471EUT and MM3Z3V0B. 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 Bug KiCad files?
From the korandiz/fmtx repository on GitHub, at the commit this page was made from: the board is kicad/bug.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bug design in my own project?
Its repository states no licence, so its author keeps all rights: ask korandiz before reusing the design.
