freeDSP ADAU1452 with 8 analog input, 8 analog outputs, S/P-DIF I/O, ADAT I/O, USB Audio Class2, WiFi, Bluetooth
It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
27 parts, built around the CMI-1210-5-95T. 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 sugantharjunan/Arduino-expansion-Board repository on GitHub, at the commit this page was made from: the board is PCB.kicad_pcb and its schematic PCB.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 sugantharjunan before reusing the design.
