Our Mission
The Embedded Operating Systems Research Foundation is a 501(c)(3) public charity (EIN 41-4821627). We exist to advance open-source embedded systems research, education, and technology for the public benefit, accountable to our community, not to shareholders. Every line of code we publish is MIT licensed and free, forever.
The kernel, bootloader, drivers, build tools, and every application we ship are MIT licensed and developed in public on GitHub. No paid tiers, no license fees, no vendor lock-in.
14 full-length technical books, free certification exams, a Kids Edition for classrooms, and paid internships for students and new graduates, all at no cost to learners.
We publish our research openly, including patent filings for health-monitoring hardware, so that clinicians, universities, and other nonprofits can build on the work rather than license it.
