Very exciting! Happenstance yesterday renewed my interest in DIYing a CM4-based laptop motherboard replacement, and having more open designs to learn from will only help that. I'm looking at qty=1 so expensive components aren't such an impediment...
I wish more designs would go open when they're no longer commercially viable. All it's going to do in the long term is breed better hardware designers, after all.
Thanks for the reply. Sorry about the supply chain problems, very frustrating.
