1.0INTRODUCTION

EasyMP3 Shield is an Arduino shield which integrates serial MP3 module and provides            
perfect integrated MP3 and WAV hardware decoding with any Arduino projects. It is            
compatible 3 with Arduino Uno, Arduino Duemilanove, Arduino Mega2560, Arduino         
Leonardoandpossiblyotherpincompatiblemainboards.

EasyMP3 shield offers high quality audio solution with the ability to decode and play MP3              
audio files from storage drives. It has also on board 2 channel differential amplifier for direct               
driveofexternalloudspeakersandstereoaudiojacksocketforearphones.

EasyMP3 shield also provides easy and stable UART interface for users to communicate with             
MP3 module using Arduino boards. With provided library, users can give commands to the             
module through UART easily to carry out MP3 player functions such as play song, increase              
or decrease volume, playback, etc. There are 3 push buttons onboard for users to carry out               
basicMP3functionsdirectlywithoutusingUART.

EasyMP3 shield comes with microSD slot which serves as MP3 and WAV file storage for the               
users. For easier management of files in microSD, the shield also comes with USBMicroB             
socket which allows user to connect the shield to PC and manage the files directly, just like                
SD card reader! Besides that, thumbdrive slot is also another alternative for users who prefer              
tousethumbdriveasfilestorage.

EasyMP3 shield has stackable side headers which allows more Arduinocompatible shields to           
be stacked on top of it. This shield provides digital pins options for software and hardware               
