The Interrupt community comprises engineers, hobbyists, and enthusiasts with a shared passion for hardware and firmware development. We come together to share best practices, problem-solve, collaborate on projects, advance the embedded community, and elevate device reliability engineering (DRE).

The Interrupt Community was created and is moderated today by the founders of Memfault.
