MP3 Player Module with VS1053 Decoder/Encoder US$8.00

MP3 Player Module with VS1053 Decoder/Encoder

MOD-MP3-X is an MP3 player module using the VLSI VS1053 Ogg Vorbis/MP3/AAC/-WMA/MIDI audio decoder and an IMA ADPCM and user-loadable Ogg Vorbis encoder. It supports VBR (variable bit rate) for MP3 and supports streaming.

This module has two modes of operation:

  • Standalone mode In this mode, the VS1053 controls the playback of files written on a microSD card inserted in the board. You are provided with controls for volume, sound effects, starting, stopping and sequencing of files to play.
  • UEXT playback mode In this mode, the board can be connected as a slave device to a host microcontroller which streams data to the codec via SPI.
This version of the board does not have the microcontroller pictured. A third mode of operation is possible with the MOD-MP3-X and MOD-MP3-X-BAT variants of the board, which have the STM32 MCU shown in the picture. With those versions, the on-board MCU can accept user commands via UART such as directory listing, file selection and volume control.

The board has both a barrel connector and screw terminals for connecting a power source.

UEXT Connector

The UEXT connector provides a solderless way to connect this MP3 module to a system with a microcontroller. There are dozens of microcontroller systems and development boards that can connect to this module via UEXT using the supplied cable. Click on the architectures below for lists of compatible boards:
