It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
74 parts, built around the NAU88C22YG. 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.
From the Neotron-Compute/codec-test-nau88c22 repository on GitHub, at the commit this page was made from: the board is codec-test-nau88c22.kicad_pcb and its schematic codec-test-nau88c22.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Neotron-Compute before reusing the design.
