STK503 User Guide

Introduction

STK503 is a top module to the STK500 development board from Atmel

Corporation. It adds support for 100-pin AVR microcontrollers (ATmega2560,

ATmega1280 and ATmega640).

STK503 includes connectors and hardware allowing full utilization of the features

of these devices, while the Zero Insertion Force (ZIF) socket makes it easy to

use TQFP packages for prototyping.

This user guide is a general getting started guide as well as a complete technical

reference for advanced users.
