Questions
How big is the Audio DSP PCB?
It measures 190 × 135 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Audio DSP use?
545 parts, built around the LM4562NA, TL072, PCM1804DB and PGA2311P. 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 Audio DSP KiCad files?
From the HeinVerhallen/Audio-DSP repository on GitHub, at the commit this page was made from: the board is KiCAD/Main board/Main board.kicad_pcb and its schematic KiCAD/-15V SEPIC/-15V SEPIC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Audio DSP design in my own project?
Its repository states no licence, so its author keeps all rights: ask HeinVerhallen before reusing the design.
