Design and specifications
#########################

:bdg-danger:`Work in progress`

.. todo:: Add details about all the schematic sections.

If you want to know how BeagleY-AI is designed and the detailed specifications, then
this chapter is for you. We are going to attept to provide you a short and crisp overview
followed by discussing each hardware design element in detail.

.. tip:: For board files, 3D model, and more, you can checkout the `BeagleY-AI repository on OpenBeagle <https://openbeagle.org/beagley-ai/beagley-ai>`_.
