An Arduino-compatible MP3 shield based on the VS1053B audio codec from VLSI. It decodes all major audio formats — including MP3, OGG Vorbis, AAC, WMA, FLAC, WAV, and MIDI — and can record in Ogg Vorbis, IMA ADPCM, and 16-bit PCM from the onboard microphone or line-in input.
With an SD card slot on the reverse side, you can play audio files directly from an SD card. The VS1053 also features EarSpeaker spatial processing for realistic stereo headphone playback, and can drive 30 Ω headphones without an external amplifier.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
