This is something I should have purchased ages ago, but didn't know it existed. Pi Zero sized LAN interface with some USB too. Normally I use a USB-LAN dongle but as you can see I mounted the board without enough space to connect one (oops). It connects using a neat little USB-USB adapter, and doesn't use any GPIO pins so no conflicts with any boards you add on top. Get from your fave Pi shop. Or Amazon.
