SparkFun MP3 Player Shield

The SparkFun MP3 Player Shield is a remarkable MP3 decoder that enables you to store music files on a standard microSD card, allowing you to enhance any project with music or sound effects. This board facilitates the extraction of MP3 files from a microSD card and plays them using only one shield, effectively transforming any Arduino into a fully operational stand-alone MP3 player. The MP3 Shield employs the VS1053B MP3 audio decoder IC to decode audio files. In addition to MP3, the VS1053B can decode Ogg Vorbis/MP3/AAC/WMA/MIDI audio and encode IMA ADPCM and user-loadable Ogg Vorbis.

The VS1053B accepts its input bitstream via a serial input bus (SPI). Once the stream has been decoded by the IC, the audio is dispatched to both a 3.5mm stereo headphone jack and a 2-pin 2.54mm pitch header.

The shield comes with all components as shown in the images and schematic. However, it does not come with headers installed. It is recommended to use the Arduino R3 Stackable Header Kit.

The SparkFun MP3 Player Shield is equipped with a 3.5mm audio out jack, a 2.54mm spaced header for speaker out, and a microSD card slot.

The product comes with comprehensive documentation including a schematic, Eagle Files, Datasheet for VS1053B, a Hookup Guide, and GitHub resources which include Design Files, Library, & Example Code.

Whether you're looking to create a sound-based interactive installation, a DIY music player, or just want to add high-quality audio to your next Arduino project, the SparkFun MP3 Player Shield offers a versatile and easy-to-use solution.
