Connector contact rating
✕ errorcurrent/connector-pin
What it looks like
J1 pin VBUS carries up to 3 A but one contact is rated 1.5 A.
What it checks
Current entering or leaving the board through a connector pin, checked against that pin's declared contact rating. Errors past the rating, warns when it runs close.
Why it matters
Connector contacts are usually the weakest current path in the whole design — a contact run past its rating heats, oxidizes, raises resistance, and heats more. Melted connector housings are one of the most common real-world hardware failures.
How to fix it
Spread the current across multiple pins (the standard trick — it's why power connectors gang pins), pick a heavier connector series, or reduce what flows through the board edge.
