All About Circuits is one of the world’s largest and most active independent online communities for electrical engineers.

Founded in 2004 with only a forum and open-source textbook, AAC has grown over the years into a thriving community of engineers collaborating and sharing expertise.

AAC provides resources and facilitates discussion amongst EEs to provide real-world solutions to the challenges they face today. Whether you’re learning RF design, honing your PCB layout skills, figuring out Verilog, or looking for inspiration for your next design, AAC is your home for technical information, news, and tools.

Content From Industry Experts

AAC provides free access to technical resources for engineers around the globe, including tools, guides, textbooks, and technical articles.

These resources are built from the ground-up to educate both engineers who are new to the industry and those who are looking to continue their professional development

Network of Engineers

Our writers are a community of EE experts who draw on their experience to develop the free, accessible resources they wish they could have found when they were learning.

AAC gives electrical engineers who are passionate about their field a way to connect with their peers—and helps shape the education of the next generation of engineers.
