Ethernet Hub and USB Hub w/ Micro USB OTG Connector
One can never have enough socks, or USB ports. Add some more USB and Ethernet capability to your Raspberry Pi Zero or, really, any kind of tablet or computer with an OTG connector with this USB 2.0 and Ethernet Hub!
This handy combo-hub has 3 USB 2.0 ports, and an RJ-45 Ethernet adapter. This chipset is really common and can be used by any Linux, Mac or Windows computer. It's particularly handy for the Raspberry Pi Zero or Raspberry Pi Zero W which are tight on USB ports and has no Ethernet out.
