 +Although the ODROID-U3 is a cost-effective ARM single-board computer, it sports a quad-core Samsung ARM SoC.\\
 +The specifications on the ORDOID-U3 include a Samsung Exynos 4412 quad-core ARM Cortex-A9 1.7GHz SoC, Mali-400 MP with 4 GPU Cores, three USB 2.0 host ports, one 10/100MB Ethernet port, 1080p video output via micro-HDMI, 2GB of LP-DDR2 system memory, eMMC and micro-SD for storage, and supports Debian Wheezy, Ubuntu 14.04 Linux, Arch Linux, Kali Linux and Android Jellybean Operating Systems.
