This is the DFRduino Mega 2560 V2.0. It is fully compatible with Arduino Mega 2560 R2. This board features the ATmega8U2 programmed as a USB-to-serial converter and it has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU.
The cool thing about our new DFRduino microcontroller is that the hearders with different colors are used to feature I/O ports of different types, red for Power Section, blue for Analog I/O, green for Digital I/O. These colors match our sensor cables. This makes it really easy to figure out where to connect sensors.
Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that 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).
The Arduino Mega is a microcontroller board based on the ATmega1280/2560. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), 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. The Mega is compatible with most shields designed for the Arduino Duemilanove, Diecimila or Uno.
