Nice to know they care and don't just ship anyways (it would probably work anyways in many cases, but cause lots of frustration).
Since the author didn't mention it in the article, the "magnetics" are actually small transformers that filter noise, DC and make it harder to fry your board via the network port.

- sdfjkl 15y agoNo, they're real transformers, electrically separating board from network. Here's a schematic (first picture from the top, the box labeled Integrated Ethernet Connector): http://www.conformity.com/artman/publish/printer_139.shtml http://www.conformity.com/artman/publish/printer_139.shtml Alternatively these can be mounted as as separate component[1] on the board in conjunction with the "plain" type of connector that the Raspberry manufacturers used by accident.

- AlexandrB 15y agoInteresting. I always wondered what those little black boxes on NICs were - but I never bothered looking them up. It's pretty amazing that modern manufacturing can fit that kind of component into the ethernet port itself.
