Audio Alert v2.3
This Audio Alert board is placed between an audio source and an audio consumer such as an FM transmitter or amplifier. When the alert box wirelessly receives an encoded message, it breaks into the audio stream from the source and plays the mp3 sound clip related to the message received. The board has 3 MP3 file sources: NOR Flash, USB memory stick, and SD card.
Software, schematic, parts list, and 3D STL files for a printed case can be found here: https://www.thingiverse.com/thing:3102114
The page pointed to by the URL also contains a slightly more detailed description of the board.
