DFRobot DFRduino - DFRobot DFR0216, DFRduino Uno V3.0 from DFRobot is a physical world computing board of small size for academics or development. It is a simple microcontroller board fully compatible with Arduino UNO R3 and the 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 the DFRduino is still using the DIP package AVR Chip. You could remove it to update or re-program the chip's firmware, or even to place it on a finished, more compact project.The DFRduino microcontroller uses different colours to feature I/O ports of different types: Red for Power Section. Blue for Analogue I/O. Green for
