DFRduino UNO R3 (Arduino UNO Compatible) Microcontroller Board - 

DFR0216 is a DFRduino UNO R3 physical world computing board of small size for academics or development. It is a simple MCU board fully compatible with Arduino UNO R3 and Arduino IDE open-source development environment. This environment implements the processing / wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP). The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux). This board features the ATmega16U2 programmed as a USB-to-serial converter. An added bonus is that our DFRduino is still using the DIP package AVR Chip. You could remove it to update or reprogram the chip's firmware, or even to place it on a finished, more compact project. The cool thing about our new DFRduino microcontroller is that the headers use different colours to feature I/O ports of different types: red for power section, blue for Analog I/O and green for digital I/O.
