The Atmel® XMEGA-A1 Xplained evaluation kit is a hardware platform for evaluating the Atmel ATxmega128A1 microcontroller. The kit offers a range of features that enable the Atmel AVR XMEGA® user to get started using AVR XMEGA peripherals right away and understand how to integrate the AVR XMEGA device in their own design.

NOTE: The XMEGA-A1 Xplained can be used to evaluate the XMEGA A1/A3/A4 and A1U/A3U/A4U devices. The devices shares the same peripherals, but the A1, A3 and A4 devices has different pin count and hence different number of each peripherals. The difference between A and AU devices is that AU features a USB Full-speed Device module. This USB module can be evaluated using STK600 or the XMEGA-A3BU Xplained.
