Welcome to new site for BeagleBoard.org docs!

Why are we doing this?

We believe in making computers open again to democratize technology and empower individuals and organizations to explore, experiment, and create without the constraints of proprietary systems.

What are we doing?

We design versatile and affordable single-board computers to provide developers, hobbyists, and educators with a platform for prototyping, experimentation, and production of embedded systems. Our comprehensive documentation, tutorials, and vibrant online community support users in their projects and foster knowledge sharing.

How are we doing it?

Through open-source hardware designs, diverse software support, and active community engagement, we enable users to customize, innovate, and collaborate effortlessly in embedded computing.

Support us

The BeagleBoard.org Foundation is a Michigan, USA-based 501(c)(3) non-profit corporation existing to provide education in and collaboration around the design and use of open-source software and hardware in embedded computing.
