Cb3 Lubuntu-12.10-desktop Nand Installation V1.00

Cubietruck is the 3rd board of cubietech, which is also named
cubieboard3. The board features an Allwinner A20 ARM Cortex-A7 dual core
processor with Mali 400 MP2 graphics, 2GB of RAM, HDMI, Gigabit
Ethernet, WiFi, Bluetooth, and a microSD card slot. There’s nothing too
surprising in those specs, but here’s what sets this developer board
apart from a tablet with its screen ripped off. The Cubietruck has a
SATA 2.0 interface, 2 USB host ports, SPDIF, a headphone jack, IR port,
and 4 LED lights. It also has 54 extended pins including UART, PS2, and a
bunch of other options. Read more about cubietruck, please refer to here.

Lubuntu is a fast and lightweight operating system developed by a
community of Free and Open Source enthusiasts. The core of the system is

selection of light applications. It’s official site is lubuntu
