Just buy the current one, I bought one right when they first came out and it’s still great!

The project it looks based on is Meshtastic, the nodes are pretty cheap, you can even find them on Amazon if your truly desperate.

My dumbass thought that was an aerial photo

What hardware are you using to attach the Pi the PCI slot?

I have a stock PiKMV V3 attached to my home server that seeing this I now need to upgrade!

Can’t believe I’ve never heard of this before, thanks for the tip!

This exact thing started happening to me too, It’s been drinking me crazy.

Hoping someone has a solution.
