MP3 Shield

Retired Product

This is a retired product. There is an updated version available: DEV-10628

Replacement:DEV-10628. The new version of this board incorporates an SD card reader. This page is for reference only.

The MP3 Shield wires your Arduino up to a VS1053B MP3 audio decoder IC, providing it with the ability to decode audio files. The VS1053 is also capable of decoding Ogg Vorbis/MP3/AAC/WMA/MIDI audio and encoding IMA ADPCM and user-loadable Ogg Vorbis.

The VS1053 receives its input bitstream through a serial input bus (SPI). After the stream has been decoded by the IC, the audio is sent out to both a 3.5mm stereo headphone jack, as well as a 2-pin 0.1" pitch header.

The shield’s power is taken from the ‘5V’ pin of your Arduino and regulated to both 3.3V and 1.8V to power the VS1053B.

This shield comes populated with all components as shown in the images and schematic; but it does not come with headers installed. We recommend the 6 and 8-pin stackable headers.
