DFRduino Duemilanove 328 (Arduino Compatable Clone)

This is the Chinese Clone of the Smartprojects Arduino USB Board.  If you purchase one of these boards,  we would greatly appreciate a review of them below.  Let us know of any differences you come across and any cool projects you have used them for!  - Madz   Introduction The DFRduio Duemilanove is 100% compatible with original with Arduino.  The Arduino Duemilanove is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
