These are new unused, old stock.  Most have not been opened, 1 or 2 were opened for pictures in a static safe way.

This lot was manufactured in the UK, I don't know if that matters to you or not, but it is different from the others I have seen listed.

These do not include a micro SD card.

They are the v1.1, which means they have the 4 core, 32bit.  1G ram.

These units were purchased as spare parts for a production line.  60+ were in use, and it was critical enough to buy spares assuming that they would have a short usable lifetime.  It turns out over about 5 years, I believe 5 were replaced before the line was discontinued.

Minimum required for use:

micro SDHC 8G 

power supply (micro usb)

network cable to existing network

Recommended for use:

keyboard & mouse (USB A)

hdmi cable to monitor
