Questions
How big is the PowerAmpSupply PCB?
It measures 80.5 × 40 mm and has 4 copper layers, 1.61 mm thick.
What parts does the PowerAmpSupply use?
119 parts, built around the TPS7A2401DBV, BZT52C10, EPC2306 and BZT52C12. 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 PowerAmpSupply KiCad files?
From the BlockWorker/ModularAudio repository on GitHub, at the commit this page was made from: the board is PowerAmpSupply/PowerAmpSupply.kicad_pcb and its schematic 12VLDO/12VLDO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PowerAmpSupply design in my own project?
Its repository states no licence, so its author keeps all rights: ask BlockWorker before reusing the design.
