rates
 Operates from a single supply (VCC =
3.6...6.0V) (Note: other pins are not 5Vtolerant.
Do not drive other pins over
DVDD!)

 SPI FLASH for code and/or data storage
 MicroSD connector for data storage
 Most internal nodes are routed to pinheaders
for easy access and customization

Description
The VS1000 Module is a small, low-cost, high
performance, easy to use audio player that is
controlled from the IO-pins or UART. 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 using
free Integrated Development Tools (VSIDE)
for the VS1000 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 possibe
to use standard DIL32 ZIF sockets or
solder it by using DIL32 footprint.
The left row of the PCB has digital connections
for external buttons, LEDs or other circuitry.
The right row has power connections,
analog connections, a serial port and USB.
These can be used to interface the board with
a PC and VSIDE or a host microcontroller.
The VS1000 Module operates from a single
power supply. The board has 16 Mbits of onboard
FLASH and a microSD card connector
for playing license free Ogg Vorbis audio
files. The module can boot from the on-board
FLASH memory.
