The Atmel
XMEGA
A1U Xplained Pro evaluation kit is a hardware platform
to evaluate the ATxmega128A1U microcontroller.
Supported by the Atmel Studio integrated development platform, the kit
provides easy access to the features of the Atmel ATxmega128A1U and
explains how to integrate the device in a custom design.
The Xplained Pro MCU series evaluation kits include an on-board
Embedded Debugger, and no external tools are necessary to program or
debug the ATxmega128A1U.
The Xplained Pro extension kits offers additional peripherals to extend the
features of the board and ease the development of custom designs.
