Here is another MP3 shield from Cytron, the ezMP3 Shield is an Arduino compatible shield that is compatible with Arduino UNO, Maker UNO, CT-ARM, and possibly other pins compatible mainboards. Cytron ezMP3 Shield offers a high-quality audio solution with the ability to decode and play MP3 audio files from a microSD card.

Cytron ezMP3 Shield has stackable side headers which allow more Arduino shields to be stacked on top of it. Users can stack for example LCD Keypad Shield or Graphic LCD Shield and utilize it as a control panel for ezMP3 Shield. It has the onboard MicroSD socket for a microSD card with MP3 files. Cytron ezMP3 Shield has also an onboard 2 channel differential amplifier for direct drive of external loudspeakers.



On top of its many features, we like it because the MP3 decoder access the MP3 files directly on the microSD card, freeing up the Arduino processor for other tasks while the MP3 file is being played. Awesome!

Note: This Cytron ezMP3 shield is different from the Cytron MP3 shield, so the library is not compatible.
