This hands-on, beginner-friendly book guides hobbyists and makers through every step of creating a custom printed circuit board (PCB), from conception through production. Based on a popular university course, this book is a fun, practical guide to designing printed circuit boards (PCBs) for readers of all skill levels - no industry experience required. Readers will learn to transform a breadboard prototype into a professional-grade PCB. More than that, this book bridges the gap between a basic understanding of electronic design and the methods used to manufacture those designs in a reliable, consistent, and scalable manner. Software-agnostic exercises are provided throughout, allowing readers to try out new concepts no matter what design platform is used. By the end, they'll be ready to develop their own custom electronics.
