Breakout Board for VS1053 MP3 and MIDI

The VS1053 is a great MP3 decoder, and with this breakout board, it's easy to drop it into any project. The VS1053 is capable of decoding Ogg Vorbis/MP3/AAC/WMA/MIDI audio and encoding IMA ADPCM and user-loadable Ogg Vorbis. Can drive 30 Ohm headphones with no additional power supply..

Note: We discovered an obscure issue with these boards. The TEST pin needs to be tied in to IOVDD or else some erratic behavior in certain circumstances. For our remaining stock, we tied these pins together with a jumper wire, as seen in the pictures. We have a new version which fixes this issue.
