Cubieboard1 is a small (10x6cm), hacker friendly, extendable, very low-cost, and powerful ARM board with Allwinner A10 SoC. It features a 1 GHz ARM Cortex A8 CPU, with 1GB of DDR3 RAM, a very powerful Video Encoding/Decoding VPU, a Mali400 OpenGL ES GPU, and 96 expansion headers which can be used as GPIO, I2C, UART, LVDS, PWM, SPI, CSI, and so on.
After about half year of cubieboard1's born, cubietech brought an another board, cubieboard2 to the cubie fans, which is totally compatible with cubieboard1. It share the same PCB with cubieboard1, but with a dual core CPU and a dual core MALI400 GPU.
Cubieboard2 Dual-Card Version which named Cb2-2card for short is also a open-source hardware and shares the same PCB with cubieboard2. It has all the features like cubieboard2 except the on-board 4GB NAND Flash. But Cubieboard2 Dual-Card Version has 2 TF card slots and it supports more flexible storage media configuration. This board has lower costs and very suit for geeks and hobbyists.

While cubieboard1/2 very suitable for student, software/hardware hackers, cubietruck(cubieboard3) is suitable for us to make real product.
Cubietruck is the 3rd board of Cubieteam, so we also name it Cubieboard3. It's a new PCB model adopted with Allwinner A20 main chip,just like Cubieboard2. But it is enhanced with some features, such as 2GB memory, VGA display interface on-board, 1000M nic, WIFI+BT on-board, support Li-battery and RTC,SPDIF audio interface.
