INTRODUCTION:
Page 1
MOD-MP3-X is MP3 player module based on VS1053 Ogg
Vorbis/MP3/AAC/-WMA/MIDI audio decoder and an IMA ADPCM and userloadable Ogg Vorbis encoder; supports VBR (variable bit rate) for MP3; Supports
streaming. It also employs an on-board STM32F103RBT6 CORTEX-M3 microcontroller 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 directory listing, selecting of a file to play and playback and volume control.
MOD-MP3-X ships in two variants – with and without battery. The battery
variant employs a Li-ion 3.7 V, 1200 mAh rechargeable battery and an on-board battery charger.

ELECTROSTATIC WARNING:
Page 2
The MOD-MP3-X board is shipped in protective anti-static packaging. The board
must not be subject to high electrostatic potentials. General practice for working
with static sensitive devices should be applied when working with this board.
BOARD USE REQUIREMENTS:
Cables: The cable you will need depends on the programmer/debugger you use. If
you use ARM-JTAG-EW, you will need USB A-B cable, for all types programmers
you will need ARM-JTAG-20to10 adapter.
Hardware: Programmer/Debugger ARM-JTAG-EW , ARM-USB-OCD, ARMUSB-TINY, ARM-USB-TINY-H , ARM-USB-OCD-H or other compatible
programming/debugging tool. For EEPROM programming you can use PICkit 2
development programmer/debugger from Microchip, because we don't offer a
suitable programmer, yet.

MOD-MP3-X-BAT (only):
POWER SUPPLY CIRCUIT:
MOD-MP3-X is typically power supplied with 5 VDC.
The programmed board power consumption is about 70 mA with all peripherals
enabled.
RESET CIRCUIT:
MOD-MP3-X reset circuit for VS1053 includes RC group - R7 (100kΩ) pullup and C12 (100nF), jumper MP3_RST, jumper VLS_RST, STM32F103RBT6 pin 43
(PA10/USART1_RX/TIM1_CH3) and VS1053 pin 3 (XRESET).
Note, that if VLS_RST jumper is closed, STM32F103RBT6 must not control
the VS1053 RESET, because VLS_RST is connected to ground.
MOD-MP3-X reset circuit for STM32F103RBT6 includes R36 (10kΩ) pullup, STM_RST jumper, SWD pin 10 and STM32F103RBT6 pin 7 (NRST).
Page 11
CLOCK CIRCUIT:
Quartz crystal Q1 (12.288 MHz) is connected to VS1053 pin 17 (XTALO)
and pin 18 (XTALI).
Quartz crystal Q2 (8 MHz) is connected to STM32F103RBT6 pin 5
(PD0/OSC_IN) and pin 6 (PD1/OSC_OUT).
JUMPER DESCRIPTION:
UEXT/BAT
When this jumper is shorted in position UEXT – the board is power suppied via
UEXT. When this jumper is shorted in position BAT – the board is power supplied via
BATTERY, USB or external power supply.
Default state is shorted in position BAT.
BOOT_E
SA_E
When this jumper is closed, codec is able to boot firmware from EEPROM. This is for
standalone mode.
Default state is closed.
This jumper connects SPI2_MOSI signal with SPI1_SCK signal.
Default state is closed.
DREQ_E
This jumper connects SPI1_SCK signal with DREQ signal.
Default state is closed.
MP3_RST/TXD and DREQ/RXD
When these jumpers are shorted in position MP3_RST and DREQ, the codec is
controlled direct via UEXT, without involving STM32F103RBT6. When these jumpers
are shorted in position TXD and RXD - via the UART interface of UEXT may be
submitted to STM32F103RBT6 commands to operate the codec.
Default states are shorted in positions MP3_RST and DREQ.
VLS_RST
STM_RST
When this jumper is closed, STM32F103RBT6 must not control the VS1053 RESET,
because VLS_RST jumper connects VS1053 pin 3 (XRESET) to ground
Default state is opened.
When this jumper is closed, STM32F103RBT6 is in reset.
Default state is closed.
R-T
This jumper connects RST signal with TRST signal.
Default state is opened.
BCD
This jumper connects the battery charger input and output. When is closed the battery
charger is disabled.
Default state is opened.

Jumpers description for changing EEPROM firmware:
–SA_E, BOOT_E and DREQ_E – opened
–STM_RST and VLS_RST – closed
–DREQ/RXD – closed in position DREQ
–MP3_RST/TXD – closed in position MP3_RST
–UEXT/BAT – closed in position BAT (position of this jumper depends on the source of
power that you will choose)
In this jumper position you can program on board EEPROM with the proper programmer
(for example PICkit2). Note that you have to make custom adapter cable between
EEPROM programmer and EEPGM connector. See EEPGM connector description below.
Commands for UEXT smart control mode:
In this mode STM32F103RBT6 firmware has extra - Mass storage device, through
which you can save MP3 files to the SD card.
In this mode you can use RXD and TXD signals of UEXT connector to communicate
between MOD-MP3-X and your computer. For this purpose, for example, you can use our
module MOD-USB-RS232, which creates a virtual COM Port. The COM Port setting are
9600bps 8N1.
You can also use other our boards with UEXT to connect with MOD-MP3-X.
It is the list of used commands:
Note: For the latest version visit our site: www.olimex.com/dev
- "L" - lists the current directory and return its contents, directories are marked with
a <DIR> tag
- "CDIRNAME <name>" - switch the current directory to <name>, name should be
up to 8 characters long
Page 13
- "cnum <index>" - switch the current directory to the one with given <index>, as
displayed with the "L" command
- "." - returns to the parent directory, no higher than the root directory
- "PSONGNAME <name>" - plays file in the current directory by its <name>,
<name> should be in 8+3 format and the only extension supported is ".MP3"
- "pnum <num>" - plays file in the current directory by its <index>, starting from 0.
<index> may be calculated by the sequence number displayed with the "L"
command minus the number of directories in the current directory.
- "OFF" - turns the codec chip OFF, may be executed at any time
- "ON" - turns the codec chip ON, may be executed at any time
These commands have meaning only when playback is started:
- "C - stop playing current file, returns "Stopped."
