After looking through the internet, I coudln't find any document (not in the datasheet, no nice graphics on google image searches) that showed the mapping between the Arduino breakout board and the SAMD51. Does such a mapping exist?

I'm answering my own question below, but perhaps someone knows of a better table.

Edit: Since writing my answer, I found this Google Sheet that does a much better job.

Arduino has some schematics on their website. Here's an image I used to build the following list below.

There are in this format: Arduino Pin | SAMD51 Pin | SAMD51 Description
