Meet PINE A64: a 64-bit quad core single board computer with a expandable design. It is powered by a quad-core ARM A53 64-bit processor that runs at 1.2 GHz. You also get a dual-core MALI-400 MP2 GPU, 512 MB of RAM, a HDMI port (4k), and 2 USB ports. PINE A64+offers even more features, allowing you to add a camera, touch panel module, and other accessories.
PINE A64 can serve as a full Android 5.1 computer when paired with a keyboard and mouse. This is an open source platform. so you can load Ubuntu and OpenHAB on it. Since the data is stored on a removable MicroSD card, you can easily update or swap operating systems. Yet another cool Kickstarter project.
