Using EAGLE: Schematic

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.
