The Compute Stick comes pre-installed with the Ubuntu 14.04 LTS operating system, and is a fully-functional computer in a package similar to a large USB stick. It hosts a 64-bit 1.33GHz Intel Atom Z3735F Quad-Core processor with 2 Mbytes cache, integrated Intel HD graphics, and multi-channel digital audio. The Compute Stick plugs into any display that has an HDMI 1.4a interface. Networking is achieved with onboard IEEE 802.11 b/g/n WiFi, and peripheral connectivity is available through the Bluetooth 4.0 and USB 2.0 interfaces. Once plugged into a display’s HDMI port, the user powers the Compute Stick with a wall adapter. A status LED indicates the device is powered while both graphics and audio is provided through the HDMI port. The device can be controlled through a wireless keyboard and mouse.
The Compute Stick runs a custom build of the Ubuntu 14.04 LTS operating system direct from Canonical, with all the latest updates. The stick has 8 GBytes of eMMC Flash for user file storage and 1 GByte of RAM. Flash user storage is expandable for both versions (this and the earlier Windows 8.1 version) through a microSDXC slot on the side of the device.
