Fabricating AI On Edge Board

Hi has anyone tried building "AI on Edge kind of Fab boards" in any fab lab

Some of the examples

Nvidia https://developer.nvidia.com/buy-jetson?product=jetson_tx2&location=US

Google Coral Dev Board https://coral.withgoogle.com/products/dev-board/

What i am looking for an open source version of enabling deep learning boards. For now its pretty much Nvidia, Google and Intel in race and i don't see any open source version for it

Any help or pointers would be of great help, as i intend to use that to build my solution
