VS1103 Module
VS1103 Module
Features
Description
• Plays audio from µSD card
• Plays audio from SPI Flash (separate
firmware)
• Plays MIDI and WAV (PCM, IMA ADPCM)
• Firmware and content can be customized
• Controlled via SPI (µSD) or UART (SPI
FLASH)
• High-performance CD-quality analog out
• Supports various sample rates
• Operates from a single supply (VCC=4.0
to 6.0 V)
(Note: IO pins are not 5 V-tolerant. Do
not drive them over 3.6 V!)
• Line output
• Headphone output
• Line input
• Microphone input
• SPI FLASH for code and/or audio data
storage
• µSD connector for large audio data stor-
age
• The most useful signals are routed to
pin headers for easy access and cus-
tomization
Applications
The VS1103 Module is a small, low-cost, high-
performance, easy-to-use audio player that is
controlled from serial control interface (when
playing from µSD card) or an UART (when
playing from SPI FLASH). It can be used as
a “plug-in” audio board in electronic systems
or as a standalone small audio player.
The product is supported by design services,
audio content preparation and pre-programming.
It is also fully configurable by the user by us-
ing free Integrated Development Tools (VSIDE)
for the VS1103 IC. The use of the module
does not require any advanced information
from the user.
Pin headers of the PCB are compatible with
DIL32 footprint 2.54 pitch 15.24 mm wide (100
mils pitch, 600 mils wide). This makes it pos-
sibe to use standard DIL32 ZIF sockets or
solder it by using DIL32 footprint.
The left row of the PCB has digital connec-
tions for SPI control or other circuitry. The
right row has power connections, analog con-
nections and a serial port. These can be
used to interface the board with a PC and
VSIDE or a host microcontroller.

The VS1103 Module operates from a single
power supply. The board has either 2MBytes
(VSMD301) or 16MBytes (VSMD321) of on-
board FLASH and a µSD card connector for
audio content. The module boots from the
on-board FLASH memory.

1 DC_MEAS and LINE_IN use the same ADC input, so connect only one.
2 Due to the resistor between CS1 and MISO, MISO gets a pull-up during µSD access and a
pull-down during boot from SPI FLASH.
Note: The maximum voltage for IO pins (except RX) is 3.6V ! Only VCC can be 4.0 V -
6.0 V.
