  http://www.cnbeta.com/articles/202351.htm
       1.支持Arduino IDE 1.0+ (OSX/Win/Linux)
       2.能够通过USB或者5v或者7-35v (自动匹配)额外电源供电
       3.主板上有 500ma 5V调节器
       4.USB嵌入 (串口调试)
       5.6个I/O Pins (2个用来支持USB)
       6.8k Flash Memory (about 6k after bootloader)
       7. I2C and SPI (vis USI)
       8. PWM on 3 pins (more possible with Software PWM)
       9. ADC on 4 pins
       10.Power LED指示灯和Test/Status LED (在Pin0)

The Specs:

• Support for the Arduino IDE 1.0+ (OSX/Win/Linux)
• Power via USB or External Source - 5v or 7-35v (automatic selection)
• On-board 500ma 5V Regulator
• Built-in USB (and serial debugging)
• 6 I/O Pins (2 are used for USB only if your program actively communicates over USB, otherwise you can use all 6 even if you are programming via USB)
• 8k Flash Memory (about 6k after bootloader)
• I2C and SPI (vis USI)
• PWM on 3 pins (more possible with Software PWM)
• ADC on 4 pins
• Power LED and Test/Status LED (on Pin0)
