For future reference please fill in the template completely with the web site for the part you want which contains the pin outs and physical dimensions of the board you want. The only reason you didn’t get a message of “insufficient information to do anything with” is because I know the Waveshare site and that it typically has the needed information. This part should do what you want. Of note the POE pins do not appear in pcb view as they are on a header and the mounting holes are not drilled by default. If you want the mounting holes you need to drag the core parts / pcb / hole part in to your sketch, place it over the holes in silkscreen and set the hole size in Inspector appropriately to drill the holes.
One point - I did attempt to include the Waveshare site (https://www.waveshare.com/esp32-s3-eth.htm) which I know well. After three attempts, which the form did not accept, I gave up and sent the form as it was. Why the site did not accept it, I do not know.
Assuming you are a new user, I think the forum only allows 1 link per reply so the forum likely took the images as the first upload and denied any further ones. In this case it didn’t matter as I knew where the website is.
Yes. @jules_uk you can try (if you have the time) just swipe through topics in your free time, and chances are you might be promoted to TL1. You can then upload unlimited media in a topic (of course not so much…) and unlimited links (but each reply has a limit tho, but u probably will not reach it)
That explains it then . As I am retired, I should have enough time to go through topics (although with my microcomputer and electronics hobby, That could take a bit more time than I would hope for). As is is, this is the first part I have had any trouble locating - I like to document my circuits and Fritzing is perfect for this.
