If you are an Android developer and have been itching to get your hands on some high end, quad core hardware, than Korean company HardKernel may have just what you’re looking for. The new ODROID-X is an Android developer board (meaning it comes as just a single board computer sans case or accessories. For $129 plus shipping and customs fees, you can have a 90 x 94mm PCB with a Samsung Exynos 4412 ARM Cortex-A9 quad core at 1.4 GHz (1MB cache), Mali 400 GPU, 1GB RAM, and runs on a 5V, 2A power adapter.
IO for the ODROID-X includes headphone and microphone jacks, six USB 2.0 ports, 10/100 Ethernet, SDHC card slot, 50-pin GPIO connector, UART serial connector, MIPI-CAM camera connector, HDMI, and a power jack. In other words, it is extremely expandable. It is capable of outputting 1080p video over HDMI when using the H.264 video codec thanks to dedicated hardware acceleration. Hardkernel will happily sell you accessories but you would likely be better off buying it from a local retailer or online shop that is in-country to avoid the extra shipping and customs fees. The power jack and other ports are standard, so there aren’t any worries there. Android 4.0 ICS is reportedly available for download, though no word yet on when the newly announced Android 4.1 "Jelly Bean" OS build will be up on the site.
Thanks to the Samsung Exynos 4, you definitely have more oomph than the 700 MHz ARMv7 in the Raspberry Pi, though this board isn’t nearly as small (and costs about four times as much). If you need the extra horsepower, this may be worth considering at this price but be sure figure out the import taxes and shipping for your location to figure out what it will really cost you to get your hands on.
