Questions
How big is the Preamp PCB?
It measures 130 × 140 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Preamp use?
275 parts, built around the DIR9001PW, LM4562NA, SD103ASDM and CS4398-CZZ. 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 Preamp KiCad files?
From the djupdal/asd-amp repository on GitHub, at the commit this page was made from: the board is asd_pre_1/pcb/preamp.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Preamp design in my own project?
Its repository states no licence, so its author keeps all rights: ask djupdal before reusing the design.
