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!)

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.

Development board for VS1103 chip
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.
