The interface mode of Player can be switched via the jumper.
The green led will flash once which means the player is under UART(Serial) mode when the player startup. The green led will flash twice which means the player is under I2C mode. Once the Player is ready the green LED will stay lit
I2C pin connection:
Analog Pin4 (SDA) goes to DO
Analog Pin5 (SCL) goes to DI

Support SD Cards


  • The player has been tested with micro SD card (1G).

  • If the green led is flashing all the time which means the SD card is not ready, either not supported or not corrected formatted. And string "\Plese check micro SD card\r\n" will be returned at UART mode.
  • If the green led do not flash, it means the SD card is working properly.


Support Commands

  • Pause Play "\:p\r\n" Return "pause\r\n" if success
  • Continoue Play "\:s\r\n" Return "start\r\n" if success
  • Play next "\:n\r\n" Return "next\r\n" if success,Return "false\r\n" if failed
