Questions
What parts does the Bl speaker use?
51 parts, built around the CP2102N-A01-GQFN28R, ESP32-MINI-1 and PCM5100PW. 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 Bl speaker KiCad files?
From the jayadeep14/Esp32-project- repository on GitHub, at the commit this page was made from: the board is PCB/bl_speaker.kicad_pcb and its schematic PCB/bl_speaker.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bl speaker design in my own project?
Its repository states no licence, so its author keeps all rights: ask jayadeep14 before reusing the design.
