MP3 Shield has been designed for various applications related to voice record and play using MP3 module with memory card storage, this shield can be used as standalone mode or Digital mode by serial interface. In standalone mode it can play 16 messages with couple of other functions, Standalone operation possible by connecting resistors and push switches on ADC pins of the module check data sheet for switch connections. Digital mode provides full control of messages with serial interface. Shield also has DS1307 RTC on board to develop a taking clock or other time related applications. Board has dual audio outputs, single channel 3W direct speaker output from MP3 Module and On board 5W Stereo Amplifier based on BA5406 provided to Amplify low audio signal coming from MP3 module. 4 Tact switch with open header connector can be interface to any port of micro-controller using female to female wire harness. RC6, RC7 and RC5 pin connected to micro-controller for serial interface. DS1307 RTC pins are connected to RA0 and RA1 Port pins. Refer data sheet for Module Serial Interface, switch connections circuit for stand-alone mode.

This module is a shield for 28/40 Pin PIC Development Board

MP3 Module

DFPLayer Mini module is a serial MP3 module provides the perfect integrated MP3, WMV hardware decoding. While the software supports TF card driver, supports FAT16, FAT32 file system. Through simple serial commands to specify music playing, as well as how to play music and other functions, without the cumbersome underlying operating, easy to use, stable and reliable are the most important features of this module.
