The attached images are from a MacArthur prototype where 12V was accidentally plugged into the 1-Wire connector.
We tried to prevent that mistake by having a different color for the power connector and plug, but I can see how that can still happen by accident. Maybe we should migrate to a different type for power that doesn't fit into the other connectors.
Hi Adrian.
Thank you for your response. I don't see any of those effects on the HAT. In fact, I bought another rpi5 and it works perfectly fine with the HAT. So maybe it doesn't have anything to do with the first rpi death?
I don't really know what happened.
Thank you.
