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,, 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 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.

Pro 4 racing. 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 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 “ATMEGA328 P”). 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.
