Questions
How big is the BM62-Audio PCB?
It measures 66.4 × 33.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BM62-Audio use?
12 parts, built around the CH340E and BM62SPKA1MC2-0001AA. 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 BM62-Audio KiCad files?
From the shirokuma89dev/BM62-Audio repository on GitHub, at the commit this page was made from: the board is PCB/BM62-Audio/BM62-Audio.kicad_pcb and its schematic PCB/BM62-Audio/BM62-Audio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BM62-Audio design in my own project?
Its repository states no licence, so its author keeps all rights: ask shirokuma89dev before reusing the design.
