mikroElektronika MP3 Click Quick Start Manual

MP3 click
1. Introduction
MP3 Click is an accessory board in mikroBus™
form factor. It includes a stereo MP3 decoder
chip VS1053 which can decode multiple formats
(Ogg vorbis, MP3, MP1, MP2, MPEG4, WMA, FLAC,
WAW, MIDI), and encode three different formats
from microphone in mono or stereo format (Ogg
vorbis, IMA ADPCM, 16-bit PCM). Board uses
industry-standard Serial Peripheral Interface for
communication, and can only use 3.3V power
supply. Board features stereo headphone and
microphone audio connectors.
2. Soldering the headers
Before using your click board, make sure to
solder the provided 1x8 male headers to
both sides of the board. Please locate the
headers in the top side of the inner box of
the board package, and take them out.

Turn the board upside down, so that
bottom side is facing you upwards. Place
shorter parts of the header pins in the
both soldering pad locations.

Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
3. Plugging the board in
Once you have soldered the headers your
board is ready to be placed into desired
mikroBUS™ socket. Make sure to align the
cut in the lower-right part of the board
with the markings on the silkscreen at
the mikroBUS™ socket. If all the pins are
aligned correctly, push the board all
the way into the socket.
4. How to play music?
Using MP3 click in combination with microSD
click board, you can play music files directly from
your microSD card. You can easily implement
microcontroller software which can read mp3
files chunk-by-chunk, and send each chunk for
decoding over the same SPI communication
lines, with different chip selects for each board.
