1 Introduction
The Xplain evaluation kit is a hardware platform to evaluate the ATxmega128A1.
The kit offers a larger range of features that enables the XMEGA user to get
started using the XMEGA’s peripherals right away and to get an understanding of
how to integrate the XMEGA in their own design.

This document targets the Xplain evaluation kit revision 3 and parts of the document
may therefore be inconsistent with earlier revisions of the product. For earlier revision
please refer to the schematics, which is this only documentation available for these
revision.
The Xplain kit is intended to demonstrate the ATxmega128A1, and the hardware that
relates to the AT90USB1287 is therefore not covered in this document.

The Xplain kit comes with both the ATxmega128A1 and the AT90USB1287
preprogrammed.
The preprogrammed firmware in the XMEGA plays different sounds when the micro
switch buttons are pushed.
