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
VS1053
chip 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. Two 1x8 male
headers are included with the board in
the package.

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.
