It's hard to imagine modern multimedia devices
without high quality audio reproduction modules.
Sound and music are almost important as graphical
user interface. mikromedia
two audio power amplifiers capable of delivering
675mW of continuous average power into an 8Ω load.
Amplifiers are connected each with one speaker, thus
with mikromedia stereo VS1053 audio codec making
a stereo audio system. Speakers has maximum power
of 0.20W with 81dB maximum output sound level.
Left and right audio signals are brought to the board
directly from the mikromedia board (socket) via two
connection pins LOUT and ROUT (left and right stereo
signals). You can disconnect each off the amplifiers,
from the mikromedia socket LOUT and ROUT pins, by
placing J8 and J9 jumpers in OFF position, respectively.
After programming and testing Stereo system can be
implement in your final design.
