The PCB is expensive due to small vias. This will be arranged with bigger vias for the V2. BTW, I am not ordering it, I will do so for the V2.

USB Audio Class Device with STM32G431CB and TLV320ADC6120
It measures 37.1 × 39.5 mm and has 2 copper layers, 1.6 mm thick.
55 parts, built around the STM32G431CBT6 and LSM6DS3TR-C. 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 Gabouin/perdican repository on GitHub, at the commit this page was made from: the board is src/kicad/pcb/Perdican V1.kicad_pcb and its schematic src/kicad/schem/Perdican V1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
