Questions
How big is the Power supply and amplifier PCB?
It measures 71.1 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Power supply and amplifier use?
34 parts, built around the LM386 and S8550. 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 Power supply and amplifier KiCad files?
From the roybaer/sound_source repository on GitHub, at the commit this page was made from: the board is power_supply_and_amplifier/power_supply_and_amplifier.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power supply and amplifier design in my own project?
Its repository states no licence, so its author keeps all rights: ask roybaer before reusing the design.
