Questions tagged [ethernet-port]

The Raspberry Pi B/B+/2B/3B has a standard Ethernet port for connecting it to the internet and to a network. Other RPi versions, such as all "A" versions, the RPi Zero and the Compute Module do not have the hardware required though in some cases it may be possible to provide such connectivity with an add-on board.
