Adafruit “Music Maker” MP3 Shield for Arduino w/3W Stereo Amp – v1.0 [ADA1788]

Bend all audio files to your will with the Adafruit Music Maker shield for Arduino! This powerful shield features the VS1053, an encoding/decoding (codec) chip that can decode all kinds of audio formats such as MP3, AAC, Ogg Vorbis, WMA, MIDI, FLAC, WAV (PCM and ADPCM). It will also be used to record audio in both PCM (WAV) and compressed Ogg Vorbis. You’ll be able to 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 in order that any Arduino can play audio from an SD card. There’s also a special MIDI mode that You’ll be able to boot the chip into to be able to 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 large number of extras. That’s why we spun up the most productive shield, perfect to be used with any Arduino Uno, Leonardo or Mega. This version of the shield includes an onboard 3W/channel stereo audio amplifier that can drive 4 or 8 ohm speakers. It is the same amplifier as in our TS2012 breakout, a great class D amplifier that sounds good and is power-conscious for portable/battery usage. Volume keep watch over is handled by the VS1053 chip. We also have a version without an amplifier, when only line/headphone out is required.
