LucaudioESP32
Project inspired by sonocotta ESP audio docks.
I wanted a solution for wireless audio multiroom synchronized players, and the best I found was projects using squeezelite-esp32.
I did my own board because firstly I wanted to improve my cad skills, and also because I like bringing my own personnal touch. Project is still in development, I'm adding new features on my pcb later on

Questions
How big is the LucaudioESP32 V2 1 PCB?
It measures 92.4 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LucaudioESP32 V2 1 use?
104 parts, built around the ESP32-WROVER-E(4MB), CH340N, LP5907MFX-3.3 and PCM5102PW. 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 LucaudioESP32 V2 1 KiCad files?
From the lucococo/LucaudioESP32 repository on GitHub, at the commit this page was made from: the board is Hardware/LucaudioESP32_V2_1/LucaudioESP32_V2_1.kicad_pcb and its schematic Hardware/LucaudioESP32_V1_1_0/LucaudioESP32_V1_1_0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LucaudioESP32 V2 1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask lucococo before reusing the design.
