- 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.
