Questions
How big is the AudioAmp PCB?
It measures 145 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AudioAmp use?
59 parts, built around the SM4007PL, 1206W4F100J, CC0603KRX7R9BB104 and 1206W4F1002. 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 AudioAmp KiCad files?
From the hh-meas/amp repository on GitHub, at the commit this page was made from: the board is AudioAmp.kicad_pcb and its schematic AudioAmp.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AudioAmp design in my own project?
Its repository states no licence, so its author keeps all rights: ask hh-meas before reusing the design.
