The ODROID-XU that I ordered has arrived.
It also comes with a power supply, but you have to supply a memory card with whatever OS you want to install.
It has a bewildering array of connectors. On the front are 4 x USB 2, ethernet and
HDMI DisplayPort (big). On the back are power, USB 3, USB OTG, micro SD, micro HDMI type D, and what looks like a headphone socket.
