As the name sounds, it just another version of the Arduino, only with added features and pheripherals. It’s based on Arduino Duemilanova which is a version of Arduino having 32kb of memory at 16Mhz on an Atmega328. However this board that I am going to talk about features an on-board real time clock, including a SD card adaptor. Apart from the above two it also has an on-board RGB led, and an already interfaced external memory chip along with support to connect a Dht11 sensor which is a temperature and humidity sensor working on SPI protocol
The board should be configured as Arduino Duemilanova on Arduino IDE. A jumper is used to select the FT232 chip output level. The FT232RL enables you to programme a new firmware or change the bootloader without the need of extrernal programmer .The board power supply has to be manually configured. All the schematic and required code files are included and can be downloaded. Overall a good project, but I believe better board are availabel with more pheripherals on-board and with a better version of Arduino.
