INTRODUCTION
AVR-PX128A1
board is entry level development board for the new AVR XMEGA
TM
A Microcontroller family of devices produced by Atmel Corporation.
With AVR-PX128A1 you can explore the features of XMEGA A family on budged,
the board have everything necessary to build simple applications: USB port where
power is taken and power supply circuit, reset and oscillator circuits, JTAG and PDI
port for programming and debugging, LCD, status LED and two user buttons.
Although very simple this board will allow you to easily build USB application like
USB mass storage device, USB Audio class device, USB to Virtual RS232 port. There
are plenty of GPIOs on extension headers where you can connect your additional
circuits.
