Overview
Audio source controller is an open-source printed circuit board by johngian, from the johngian/audio-source-controller repository on GitHub. It is a 2-layer board with 10 parts on 60 nets.
It is built around the ESP32-WROOM-32. Its parts include 6 diodes, 3 switches and 1 IC. It belongs with the audio and music boards and the ESP32 boards of this library.

Problem
I have a pair of good audio monitors and want to reuse them between different audio sources. Extra points if I don't need to move from the couch.
Solution
Use esp32 and make a network enabled audio source controller.
Details
- Uses low signal latching relays
- Relays can be driven directly from esp32 using 3.3V gpio ports
- Supports 3 stereo audio inputs and 1 stereo audio output

Questions
What parts does the Audio source controller use?
10 parts, built around the ESP32-WROOM-32. 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 Audio source controller KiCad files?
From the johngian/audio-source-controller repository on GitHub, at the commit this page was made from: the board is audio-source-controller.kicad_pcb and its schematic audio-source-controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Audio source controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask johngian before reusing the design.
