EzMP3 Shield is an Arduino compatible shield which is compatible with UNO, MEGA and possibly other pin compatible main boards. EzMP3 Shield offers high quality audio solution with the ability to decode and play MP3 audio files from microSD card.

EzMP3 Shield has stackable side headers which allows more Arduino shield to be stacked on top of it. User can stack for example LCD Keypad Shield or Graphic LCD Shield and utilize it as control panel for ezMP3 Shield. It has the on-board mircoSD socket for microSD card with MP3 files. EzMP3 Shield has also on board 2 channel differential amplifier for direct drive of external loud speakers.
 
Despite its many features, we like it because the MP3 decoder access the MP3 files directly on the microSD card, free up the Arduino proccessor for other task while MP3 file is being played. Awesome!
