Questions
How big is the Usb headphone amp PCB?
It measures 50 × 85 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Usb headphone amp use?
144 parts, built around the RP2040, IA0505S, NE5532 and W25Q16JVSSIQ. 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 Usb headphone amp KiCad files?
From the embediver/usb-headphone-amp repository on GitHub, at the commit this page was made from: the board is usb-headphone-amp.kicad_pcb and its schematic usb-and-dac.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usb headphone amp design in my own project?
Its repository states no licence, so its author keeps all rights: ask embediver before reusing the design.
