1 Introduction

This tutorial is a brief introduction to PCB design using the EAGLE CAD tool. Eagle is a simple Computer Aided Design (CAD) that can be freely downloaded and used for non-commercial applications. The goal of the lab is to create a simple Printed Circuit Board (PCB). As an example circuit we use a timer (Fig. 1) to flash a LED.

The tutorial is in no way a complete guide to all functions available in EAGLE. Please refer to the EAGLE documentation, or tutorials available on the Internet for more information.
