Can you take a close look at two parts on your MacArthur HAT?
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.
- U3 CAN Driver: Do you see a small crater or an area that's bubbled up?
- D22 ESD protection diode: Is the part damaged?
