Product Description Adafruit Music Maker shield for Arduino features the VS1053, an encoding/decoding (codec) chip that can decode a wide variety of audio formats such as MP3, AAC, Ogg Vorbis, WMA, MIDI, FLAC, WAV (PCM and ADPCM). It can also be used to record audio in both PCM (WAV) and compressed Ogg Vorbis. You can do all sorts of stuff with the audio as well such as adjusting bass, treble and volume digitally. All this functionality is implemented in a light-weight SPI interface so that any Arduino can play audio from an SD card. There's also a special MIDI mode that you can boot the chip into that will read 'classic' 31250Kbaud MIDI data from an Arduino pin and act like a synth/drum machine - there are dozens of built-in drum and sample effects. But the chip is a pain to solder and needs a lot of extras. That's why adafruit has spun up one of the best shield, ideal for use with any Arduino Uno, Leonardo or Mega. Stereo audio out with proper audio filter caps and ground reference so it can be safely connected directly to headphones, a stereo system or other powered speakers. Plenty of optional breakouts for pins like the card-detect and microphone input. Full 3.3/5V level shifting for SD and MP3 chipsets. Size: 69 mm by 53 mm by 2 mm. It is RoHS compliant. Box Contains 1x MP3 Shield for Arduino
