Powered by the VS1053B codec chip, it decodes MP3, AAC, Ogg Vorbis, WMA, FLAC, WAV, and MIDI formats, and can also record audio in PCM (WAV) or compressed Ogg Vorbis.\n\nThis version includes an on-board 3 W per channel Class D stereo amplifier (TPA2012) that drives 4 or 8 ohm speakers — ideal for projects that need to be loud without external amplification. Volume control is handled digitally by the VS1053 chip. Also available without the amplifier as the Music Maker MP3 Shield (line/headphone output only).\n\nKey Features\n\n\nVS1053B Codec – Decodes MP3, MP4/AAC, Ogg Vorbis, WMA, FLAC, WAV (PCM/ADPCM), MIDI; encodes Ogg and WAV\n\n3 W Stereo Amplifier – Built-in TPA2012 Class D amp drives 4–8 Ω speakers directly\n\nMicroSD Card Slot – Plays from any FAT16/FAT32 card (64 MB or larger)\n\nStereo Line/Headphone Output – With filter caps and ground reference\n\nBuilt-In MIDI Synth – Dozens of instrument and drum sounds via 31,250 baud MIDI\n\nDigital Audio Controls – Adjustable bass, treble, and volume\n\n7 Extra GPIOs – Read buttons or drive LEDs through the Arduino library\n\nFull Level Shifting – 3.3 V / 5 V for both SD and codec chips\n\nRecording Capable – Microphone input breakout for audio capture\n\n\nCompatibility\n\nArduino UNO, Leonardo, and Mega\n\n\nIdeal For\n\nLoud audio playback without external amplification\nPortable speaker projects and boomboxes\nInteractive exhibits and talking props\nMIDI synthesiser and drum machine builds\n\n\nPackage Contents\n\n1× Adafruit Music Maker MP3 Shield with 3W Stereo Amp (assembled and tested)\n2× 2-pin terminal blocks\n1× 0.1\" male header strip\n1× 2×3 female header (ICSP)\n\n\n\nNote: Speakers, headphones, SD card, and Arduino are not included.
