MP3 Player Serial Module

The MP3 Player Serial Module is a small audio playback board that plays MP3 files and is controlled with simple serial (UART) commands from a microcontroller. Your Arduino, ESP32 or Raspberry Pi does not need to decode any audio: it only sends commands such as play, pause, next track or volume, and the module does the rest. It is a low-cost way to add music, voice prompts and sound effects to a project.

MP3 Player Serial Module Specifications

• Function: MP3 audio playback module

What's in the Box

• 1 × MP3 player serial module

Tip: Connect the module's TX pin to your board's RX pin and its RX pin to your board's TX pin, and join the grounds. Check the model printed on the board and use the matching command set or Arduino library, because serial MP3 modules from different makers use different commands.
