This book will teach you to use KiCad through a practical approach. It will help you become productive quickly and start designing your own boards. Example projects illustrate the basic features of KiCad, even if you have no prior knowledge of PCB design. The author describes the entire workflow from schematic entry to the intricacies of finalizing the files for PCB production and offers sound guidance on the process. Further full-fledged projects, of incremental difficulty, will be presented in a second book, together with a variety of advanced recipes.
