ATmega168PB Xplained Mini User Guide

Introduction

This user guide describes how to get started with the Atmel

ATmega168PB

Xplained Mini board.
The ATmega168PB Xplained Mini evaluation kit is a hardware platform to

evaluate the Atmel ATmega168PB microcontroller. The evaluation kit comes

with a fully integrated debugger that provides seamless integration with Atmel

Studio 6.2 (and later version). The kit provides access to the features of the

ATmega168PB enabling easy integration of the device in a custom design.
