Introduction

PCB design in EAGLE is a two-step process. First you design your schematic, then you lay out a PCB based on that schematic. EAGLE's board and schematic editors work hand-in-hand. A well-designed schematic is critical to the overall PCB design process. It will help you catch errors before the board is fabricated, and it'll help you debug a board when something doesn't work.

This tutorial is the first of a two-part Using EAGLE series, and it's devoted entirely to the schematic-designing side of EAGLE. In part 2, Using EAGLE: Board Layout, we'll use the schematic designed in this tutorial as the basis for our example board layout.

Suggested Reading

If you'd like to follow along with this tutorial, make sure you've installed and setup the EAGLE software. Our How to Install and Setup EAGLE tutorial goes over this process step-by-step, and it also covers the basics of what EAGLE is and what makes it great. It also covers how to download and install the SparkFun EAGLE libraries we'll be using in this tutorial. Definitely read through that tutorial before you continue on.

We'd also recommend you read and understand the concepts behind these tutorials:

Create a Project

We'll start by making a new project folder for our design. In the control panel, under the 'Projects' tree, right click on the directory where you want the project to live (by default EAGLE creates an 'eagle' directory in your home folder), and select 'New Project'.

Give the newly created, red project folder a descriptive name. How about 'Bare Bones Arduino'.

Project folders are like any regular file system folder, except they contain a file named 'eagle.epf'. The EPF file links your schematic and board design together, and also stores any settings you may have set especially for the project.

Create a Schematic

The project folder will house both our schematic and board design files (and eventually our gerber files too). To begin the design process, we need to lay out a schematic.

To add a schematic to a project folder, right-click the folder, hover over 'New' and select 'Schematic'.

A new, blank window should immediately pop up. Welcome to the schematic editor!

Adding Parts to a Schematic

Schematic design is a two step process. First you have to add all of the parts to the schematic sheet, then those parts need to be wired together. You can intermix the steps -- add a few parts, wire a few parts, then add some more -- but since we already have a reference design we'll just add everything in one swoop.

Using the ADD Tool

The ADD tool -- (on the left toolbar, or under the Edit menu) -- is what you'll use to place every single component on the schematic. The ADD tool opens up a library navigator, where you can expand specific libraries and look at the parts it holds. With a part selected on the left side, the view on the right half should update to show both the schematic symbol of the part and its package.

The ADD tool also has search functionality -- very helpful when you have to navigate through dozens of libraries to find a part. The search is very literal, so don't misspell stuff! You can add wildcards to your search by placing an asterisk (*) before and/or after your search term. For example if you search for atmega328 you should find a single part/package combo in the SparkFun-DigitalIC library, but if you search *atmega328* (note asterisks before and after), you'll discover two more versions of the IC (because they're actually named 'ATMEGA328P'). You'll probably want to get accustomed to always adding an asterisk before and after your search term.

To actually add a part from a library either select the part you want and click 'OK', or double-click your part.

Step 1: Add a Frame

The frame isn't a critical component for what will be the final PCB layout, but it keeps your schematic looking clean and organized. The frame we want should be in the SparkFun-Aesthetics library, and it's named FRAME-LETTER. Find that by either searching or navigating and add it to your schematic.

After selecting the part you want to add, it'll 'glow' and start hovering around following your mouse cursor. To place the part, left-click (once!). Let's place the frame so its bottom-left corner runs right over our origin (the small dotted cross, in a static spot on the schematic).

After placing a part, the add tool will assume you want to add another -- a new frame should start following your cursor. To get out of the add-mode either hit escape (ESC) twice or just select a different tool.

Step 2: Save (And Save Often)

Right now your schematic is an untitled temporary file living in your computer's ether. To save either go to File > Save, or just click the blue floppy disk icon -- . Name your schematic something descriptive. How about 'BareBonesArduino.sch' (SCH is the file format for all EAGLE schematics).

As a bonus, after saving, your frame's title should update accordingly (you may have to move around the screen, or go to View > Redraw).

Step 3: Adding the Power Input

Next we'll add four different parts all devoted to our voltage supply input. Use the add tool for these parts:

Part Description	Library	Part Name	Quantity
5.5mm Barrel Jack (PTH)	SparkFun-Connectors	POWER_JACKPTH	1
0.1µF Ceramic Capacitor	SparkFun-Capacitors	CAPPTH	1
Voltage Supply Symbol	SparkFun-Aesthetics	VCC	1
Ground Symbol	SparkFun-Aesthetics	GND	2

All of these parts will go in the top-left of the schematic frame. Arranged like this:

If you need to move parts around, use the MOVE tool -- (left toolbar or under the Edit menu). Left-click once on a part to pick it up (your mouse should be hovering over the part's red '+' origin). Then left click again when it's where it needs to be.

Step 4: Microprocessor and Supporting Circuitry

Next we'll add the main component of the design -- the ATmega328 microprocessor -- as well as some components to support it. Here are the parts we'll add:

Part Description	Library	Exact Part Name	Quantity
ATmega328P (PTH)	SparkFun-DigitalIC	ATMEGA328P_PDIP	1
¼W Resistors	SparkFun-Resistors	RESISTORPTH-1/4W	4
5mm LEDs	SparkFun-LED	LED5MM	3
0.1µF Ceramic Capacitor	SparkFun-Capacitors	CAPPTH	1
