Check the listing for details. Raspberry Pi 2 Model B Quad Core Rpi2 1G 2B v1.1. Color: Blue, Condition: New. Listed at 55.00 USD. 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
