Atmel ATMEGA256RFR2 Xplained Pro

Preface

The Atmel

ATMEGA256RFR2 Xplained Pro evaluation kit is hardware platform

to evaluate the ATmega256RFR2 microcontroller.
Supported by the Atmel Studio integrated development platform, the kit provides

easy access to the features of the Atmel ATmega256RFR2 and explains how to

integrate the device in a customer 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

ATmega256RFR2.
The Xplained Pro extension series evaluation kits offers additional peripherals to

extend the features of the board and ease the development of customer designs.
