Adafruit "Music Maker" MP3 Shield for Arduino w/3W Stereo Amp - v1.0

Unleash the power of audio in your Arduino projects with the Adafruit Music Maker Shield! This versatile shield features the VS1053 codec chip, capable of decoding a wide range of audio formats including MP3, AAC, Ogg Vorbis, WMA, MIDI, FLAC, and WAV (both PCM and ADPCM). It even allows you to record audio in WAV and Ogg Vorbis formats, making it a truly powerful audio tool. You can also adjust bass, treble, and volume digitally, giving you full control over the sound.

With its SPI interface, this shield makes it easy to add audio capabilities to any Arduino. Simply connect an SD card to the board, and you'll be able to play audio files with ease. The shield also supports MIDI mode, allowing it to read 31250Kbaud MIDI data from an Arduino pin and act as a synthesizer or drum machine, complete with dozens of built-in drum and sound effects.

The shield comes with a built-in 3W/channel stereo amplifier that can drive 4 or 8 ohm speakers, making it perfect for portable or battery-powered audio projects. The class D amplifier is efficient and provides great sound quality, and volume control is handled directly by the VS1053 chip. If you don’t need an amplifier, a version of the shield without one is also available for line/headphone output.

Key Features:

• VS1053B codec chip decodes a variety of formats: MP3, Ogg Vorbis, MP4, AAC, WMA, FLAC, WAV, MIDI
