Product User’s Manual – SHIELD-EZMP3
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
,
,
,
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
UART communication.
