On the next page, we'll look at the colored layers of the board editor, and see how they compare to the actual layers of a PCB. In the board window click on the Script icon -- (or go to "File" then "Execute Script"). In the file browser, select the "spk.scr" file you just downloaded and unzipped. Anything from the background color, to layer colors, to key bindings can be modified to fit your preference. Better tailoring your interface can make designing a PCB much easier. On this page we'll talk about how we at SparkFun prefer to customize our UI.

Adjust Component Position
All of the parts you added from the schematic should be there, stacked on top of eachother, ready to be placed and routed. EAGLE contains a schematic editor, for designing circuit diagrams. Schematics are stored in files with .SCH extension, parts are defined in device libraries with .LBR extension.
Creating the Board
This schematic was actually used to create the PCBs that I used in my Dice Generator project. In order to start making the schematic, right-click on your project, and click 'New', followed by 'Schematic'. All you are going to want to do is right-click on 'Projects' and select 'New Project'. Once you have named it, go back under the projects tab and you should see your new project there. Once you go back to the main menu, under 'Libraries', you should see the Adafruit library.

Learn how to successfully migrate your design and library files from Autodesk EAGLE to Autodesk Fusion with a simple, four-step guide. The timing of a project largely depends on its specifics, complexity, scale, choice of components, and logistics. For example, a project audit can take 1-2 months, while AI-based software development usually lasts much longer.

With the NAME tool selected, clicking on a net should open a new dialog. Start by naming the net connected to the top, GND pin. Delete the auto-generated name (e.g. N$14), and replace it with "GND" (sans the quotation marks).
Defining Library Parts
Creating the board from a schematic is one of the easiest tasks with EAGLE. Click the Board icon and EAGLE opens a new window with all the parts arranged next to a default board outline. All the nets from the schematic are shown as air wires. In the intricate world of electronics, every detail in your PCB layout matters. At 911EDA, we understand the nuances that transform a good design into an exceptional one.
Using EAGLE: Schematic
To begin the design process, we need to lay out a schematic. The tabs in this view (Layers, Clearance, Distance, etc.) help define a huge set of design rules which your layout needs to pass. These rules define things like minimum clearance distances, or trace widths, or drill hole sizes...all sorts of fun stuff. Instead of setting each of those manually, you can load up a set of design rules using a DRU file. And select the SparkFun.dru file you just downloaded. The title of the window will change to "DRC (SparkFun)", and some values on the other tabs will change.

Importing your EAGLE design to Autodesk Fusion
Any changes made to the schematic are automatically reflected in the board editor. Whenever you're modifying a design it's important to keep both windows open at all times. EAGLE is packaged with a handful of nifty example PCB designs. From there, under the "examples" folder open up the "arduino" project by double-clicking the red folder (or right-clicking and selecting "Open project").
Routing the Signals
Change this to 'Gerber RS-274X' and then press process job. As shown in the short video above, they help organize and keep circuits as compact and efficient as possible. Designing and manufacturing your own might seem like a daunting task, but please do not worry. After you feel like the routing is done, there are a few checks we can do to make sure it's 100% complete. Below is an example of how you might lay out your board while considering those factors. We've minimized airwire intersections by cleverly placing the LEDs and their current-limiting resistors.
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. The last step is to hit ratsnest, to watch the glorious red pour fill just about the entire area of your board.
The most recent version of the libraries can always be found in the GitHub repository. For help using GitHub, check out our Using GitHub tutorial. Basically, all you'll need to do from the main repository page is click "Download ZIP". More powerful PCB design tools out there might have a better autorouter, or nifty tools like simulators, programmers, and 3D viewers. For us though, EAGLE has everything we need to design simple-to-intermediate PCBs. It's an excellent place to start if you've never designed a PCB before.
Make sure you click on the very end of the pin when you start or finish a net route. 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.
Some parts are placed where they just have to go (the barrel jack, and decoupling capacitor). A breadboard is a solderless electronic circuit builder - perfect for proving your concept. All of these colored layers will make more sense as you continue to use and explore EAGLE. We'll also make the grid a bit less fine by setting the "Size" to 100 mil (0.1") and "Alt" to 50 mil (0.05"). Inside the "Layout" box you can set the background to black, white, or a specific color.
This should result in a warning dialog, asking you if you want to connect this net to all of the other nets named "GND" (that would be every net connected to a GND symbol). Thanks for looking out for us EAGLE, but in this case Yes we do want to connect GND to GND. 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. If you'd like to check out the reference design we did in this tutorial, you can download them here.
Much later, in 2015, a special version of EAGLE 4.09r2 was made available by CadSoft to ease installation under Windows 7. Use SparkFun's CAM files, to create Gerber files that are accepted by most fab houses. Designing a schematic is the first step in PCB design. A well-designed schematic is critical to the whole process. Scripts are a much more streamlined way to quickly configure your interface. With one click of the button, you can automatically set up all of your colors and key binds.
The remaining nets we have to make are not going to be as easy to cleanly route. For example, we need to connect the TXO pin on JP2 to the ATmega's RXD pin, all the way on the other side. You could do it, it would work, but it'd be really ugly. Instead, we'll make net "stubs" and give them unique names to connect them. Whenever a net splits in two directions a junction node is created. This signifies that all three intersecting nets are connected.
