Generic 2B17 WTV020SD Mini SD Card MP3 Sound Module features
Other Features
Supports FAT file system SD carrier, Supports playing of 4Bit ADCPM format files, Recognizes voice files automatically, Supports micro-processor and key control, Can be called for any paragraph voice playing, Saves operation data when power off, Loads voice to the SD card without assistance of software, Supports combination playing of file (including mute combination), Memory contents classified by file, Reusable mass storage voice module, Can load WAV, MP3, and AD4 audio, Uses WTV020SD as the core chip, MP3 control mode, One-to-one key control mode, Power on loop control mode, Two-line serial control mode, Has 3 green LEDs (Standby, SD Ready, SD Busy)
Instructions for Use/Warnings
How to use with Arduino: To control the mp3 player with serial port commands with Arduino, first put the cof.mp3 file with number 1 inside the advert1 folder. The busy pin does not indicate when the player stops; it is for connecting a blinking LED. Sample code for playing folder advert01, song 002.mp3 in Arduino: mySerial.print(0x7E,BYTE); mySerial.print(0x07,BYTE ); mySerial.print(0xB0,BYTE); mySerial.print(0x30,BYTE); mySerial.print(0x31,BYTE); mySerial.print(0x30,BYTE); mySerial.print(0x30,BYTE); mySerial.print(0x32,BYTE); mySerial.print(0x7E,BYTE); To check if the module is working, observe the 3 green LEDs: 1 – Standby, 2 – SD Ready (only glows if there is a valid SD Card with the cof.mp3 file inside), 3 – SD Busy (blinks when reading from SD).
