INTRODUCTION
AVR-PX128A1 board is entry level development board for the new AVR XMEGATM
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.
