SparkFun MP3 Breakout - VS1033D

The VS1033D-L is a great MP3 decoder, and with this breakout board, it's easy to drop it into any project. The VS1033 is capable of decoding MP3/AAC/WMA/MIDI audio and encoding IMA ADPCM. Can drive 30 Ohm headphones with no additional power supply. In this new revision, the board ties the TEST pin to IOVDD, better correcting the issues which were previously fixed by a jumper wire.

  • Separate Audio and Digital 3.3V supplies
  • Onboard 12.288MHz oscillator

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

2 Soldering

Skill Level: Rookie - The number of pins increases, and you will have to determine polarity of components and some of the components might be a bit trickier or close together. You might need solder wick or flux.

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

    there exists a circuit for real time midi:

    but it doesn't work with the actual BOB. i can see the blinking of midi-Led and hear a click of every midi signal, but no different high or low tones.... How to modify the circuit for use with the actual bob-board? the data sheet is no help...

    How does this one compare to VS1103b BOB? (

    Particularly regarding MIDI decoding.

    can this thing do .ogg files? I might make a minecraft music alarm clock

    • It doesn't appear that it supports the ogg files, but you can convert it to mp3. FreeRip will do this for you, though they say that ogg and mp3 are "clashing" compressions in the way that they remove different parts of the audio to make the file smaller. So, if one file is converted from ogg to mp3, it will be missing both parts, making the quality go down. Though you might not really notice it in the alarm clock. You sure try using 'calm4.ogg' in the music folder of minecraft. I still wonder why that song is in there.

    The bottom view picture is the wrong picture.
    edit: SparkFun fixed it

  • frank26080115 / about 11 years ago / 1

    Why is this wider than the previous version? You could've added AGND without making it any wider...

    Wow, nice jumper. It must be crazy difficult to solder that... unless the pick and place machine does that. idk
