BOARD FEATURES:
ELECTROSTATIC WARNING:
Vorbis/MP3/AAC/-WMA/MIDI audio decoder and an IMA ADPCM and user-
loadable Ogg Vorbis encoder; supports VBR (variable bit rate) for MP3; Supports
streaming. It also employs an on-board STM32F103RBT6 CORTEX-M3 microcon-
troller for smart control via UEXT.
MOD-MP3-X has three modes of operation:
- Standalone mode – compatible with the old revision MOD-MP3 player. In this
mode VS1053 controls the playback of files written on a micro SD card inserted in
the board. The user is provided with controls on volume, sound effects, starting,
stopping and sequencing of files to play.
- UEXT playback mode – in this mode the board can be connected as slave device to
host microcontroller which streams data to the codec via SPI.
- UEXT smart control mode – in this mode the on-board microcontroller manages
playback of files written to the micro SD card. The microcontroller acts as a slave
device and accepts user commands via UART. Commands include SD card direct-
ory listing, selecting of a file to play and playback and volume control.
variant employs a Li-ion 3.7 V, 1200 mAh rechargeable battery and an on-board bat-
tery charger.
MOD-MP3-X is MP3 player module based on VS1053 Ogg
