The Yellow arrived from Crowd Supply today. I’d lost track of it a little bit, and had not ordered a CM4. Well, guess what i cant’ seem to buy one anywhere.
Grr.
In the same boat since Yellow shipped to backers, really 
“Normal” RPIs are back in stock, mostly, so I guess we can hope CM4 will follow, soon…

Hi Andrew, welcome to the forum!
You have added ESPHome as tags for your post but I don’t understand what the relation is with your post?
I managed to borrow one from someone who had a few and will replace it when they come in stock. Always nice to have friends that share! Yellow worked out of the box as expected.
