A curated list of awesome resources for electronic engineers and hobbyists
Electronic engineering (EE) is the practice of understanding, designing and building electronic circuits. It is often differentiated from electrical engineering in that it mostly deals with low power DC electronic circuits rather than high power AC systems but there is a lot of overlap between electronic and electrical engineering.
Experimenting with and building electronic circuits is also a popular hobby and many professional resources are often equally applicable to hobbyists and vice versa.
This list is for websites, services, software, tools and more: everything that you think is awesome in the world of electronic engineering. If you have anything to add please follow the instructions in contributing.md.
