Today's build project: One Button Audio Player with Amplifier on a single board!
This will be used to provide audio to a museum exhibit. The USB-C port on the board acts like a Thumb Drive to load MP3 files into the local storage. The port can also be used for 5v Power.

It can also be configured to play different audio files each time the button is pushed. With a Raspberry Pi or Arduino controller, the board can be controlled to play audio files or sounds, removing the need to load them on the Pi or Arduino itself.
