The Adafruit Music Maker MP3 Shield with 3W Stereo Amp turns any Arduino into a powerful audio player, recorder, and MIDI synthesiser — with built-in amplification for driving speakers directly. 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.
This 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).
Key Features
- VS1053B Codec – Decodes MP3, MP4/AAC, Ogg Vorbis, WMA, FLAC, WAV (PCM/ADPCM), MIDI; encodes Ogg and WAV
- 3 W Stereo Amplifier – Built-in TPA2012 Class D amp drives 4–8 Ω speakers directly
- MicroSD Card Slot – Plays from any FAT16/FAT32 card (64 MB or larger)
- Stereo Line/Headphone Output – With filter caps and ground reference
- Built-In MIDI Synth – Dozens of instrument and drum sounds via 31,250 baud MIDI
- Digital Audio Controls – Adjustable bass, treble, and volume
- 7 Extra GPIOs – Read buttons or drive LEDs through the Arduino library
- Full Level Shifting – 3.3 V / 5 V for both SD and codec chips
- Recording Capable – Microphone input breakout for audio capture
Compatibility
- Arduino UNO, Leonardo, and Mega
Ideal For
- Loud audio playback without external amplification
- Portable speaker projects and boomboxes
- Interactive exhibits and talking props
- MIDI synthesiser and drum machine builds

Jargon buster
Plain-language definitions for the technical terms used above.
- baud
- Baud is the signalling rate of a serial connection, often used as the speed setting for UART communication. Matching the baud rate matters because both connected devices must use the same setting for readable data.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- Headers
- Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
- microSD card
- A microSD card is a small removable flash memory card used to store data such as audio, images, logs or program files. Its capacity and formatting (often FAT32 or exFAT) affect how much can be stored and whether the card needs preparing before use.
- MIDI
- MIDI is a standard way for electronic instruments, controllers, and software to send musical control messages such as notes, velocity, and timing. If a board supports MIDI, it can be triggered from keyboards, drum pads, sequencers, or other music gear rather than only from buttons or code.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
