Questions
How big is the User adapter PCB?
It measures 88.9 × 27.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the User adapter use?
44 parts. 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 User adapter KiCad files?
From the open-headset-interconnect-standard/user-adapter repository on GitHub, at the commit this page was made from: the board is User Adapter/User Adapter.kicad_pcb and its schematic Bottom Board/Bottom Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the User adapter design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
