UP has launched a crowd-funding campaign for its new developer board, the Intel-powered QuadCore x86 UP Core.
The UP Core claims the title as the “smallest quad-core x86 single board computer in the world”, and measuring just 56.5mm x 66mm (2.22in x 2.6in), it’s about half the size of a smartphone, and a thumb-length shorter than the Raspberry Pi 3.
The device can run full Windows 10, Windows IoT Core, Android Marshmallow, and Linux options, including Ubuntu, ubilinux, and Yocto. UP Core runs on a the Intel Atom x5-Z8350 QuadCore, aka Cherry Trail, offering a newer CPU than Intel’s own Minnowboard.
The device is available on Kickstarter with an estimated shipping date of August for the 16GB units, and October for larger storage options.

The Intel x86 UP Core is small enough to fit in the palm of your hand.
