Palm sized Android-based are quite common these days, most of us are already familiar with the one board which fueled this drive towards miniaturization; the Raspberry Pi. But something is looming around, waiting to unleash its power while outperforming the RasPi in the process.
The Odroid U2 is a low-cost development platform aimed at geeks willing to mess around with a small setup. The board essentially sports an Exynos 4412 SoC with four ARM Cortex-A9 cores clocking at 1.7Ghz paired with the Mali-400MP4 ticking at 440MHz all accompanied by 2GB of ram, two USB ports, microSD card storage, HDMI output, and a built-in Ethernet port. It comes with native support for 1080p playback. This roughly matches the performance of a mainstream smartphone.
This development board can easily run Android 4.0+ (and CyanogenMod) and any ARM flavor of your favorite Linux distro, that includes Ubuntu. It can be used as an HTPC, a TV-addition or even as a device which streams your content. The Odroid U2 is priced at an amazingly low price of around $89.
