MOD-MP3
rev 1.00/07-2006
MOD-MP3
is low power MP3 player module based on VS1002
hardware decoder for MPEG 1 & 2 audio layer 3 (ISO 11172-3),
MP3+V, WAV and PCM files ; supports ADPCM encoding and
decoding ; supports VBR (variable bit rate) for MP3; Supports
streaming
MOD-MP3 can work as stand alone MP3 player with single cell
1.5V battery and on board SD/MMC card, but can be connected
as slave device to host microcontroller.
The module features are:

VS1002
hardware decoder for MPEG 1 & 2 audio layer 3
plays
MP3, WAV, PCM
files
for
MP3
supports variable bit rate and streaming
very low power, works from single
1.5V battery cell
Stereo Audio output for headphones
Stereo Audio input for microphone,
ADPCM
encoding and decoding
On board
UEXT
connector for connection to host microcontroller – in slave mode it will play the bit stream from the
host microcontroller which opens possibilities for easy adding voice to industrial applications, toys, robots etc.
On board (on back side)
SD/MMC
card connector
Can work as
MP3 player
without need for host microcontroller in stand-alone mode booting the VS1002 firmware
from on-board EEPROM, in this mode the on board 3 action lever switch can perform Pause/Play, Forward and
Reverse action
PCB: FR-4, 1.5 mm (0,062"), red soldermask, white silkscreen component print
Dimensions: 57x45 mm (2.2x1.8")
