Questions
How big is the Speaker PCB?
It measures 191.5 × 139.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Speaker use?
29 parts, built around the NE5532 and TDA2822M/TR. 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 Speaker KiCad files?
From the Davey5506/Speaker repository on GitHub, at the commit this page was made from: the board is Speaker.kicad_pcb and its schematic Speaker.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Speaker design in my own project?
Its repository states no licence, so its author keeps all rights: ask Davey5506 before reusing the design.
