  RAM Size 2 K Bytes
  The Arduino/Genuino Uno can be programmed with the (Arduino Software (IDE)). Select "Arduino/Genuino Uno from the Tools > Board menu (according to the microcontroller on your board). For details, see the reference and tutorials.The ATmega328 on the Arduino/Genuino Uno comes preprogrammed with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. It communicates using the original STK500 protocol (reference, C header files).
  You can also bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header using Arduino ISP or similar see these instructions for details.
  Item Code: UNOR3
  Packaging Details: BASED ON QTY CARTOON BOX SIZE MAY VARY
  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 ATmega2560. 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 or Diecimila.
  Number of Pins 54, 100
  Item Code: MEGA2560
  Packaging Details: CARTON BOX SIZE AND WEIGHT MAY VARY BASED ON QTY
  Dimensions 0.7x1.3" (18x33mm)
  Output Max 150mA
  DC Input Up to 12 V
  Adjustable voltage regulator(3.3V/5V)
  Item Code: PROMINI5V
  RAM Size 32 KB, 1 KB
  Number of Pins 28, 64
  1.0 pinout: Added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board
  In future, shields will be compatible with both the board that uses the AVR, which operates with 5V and with the Arduino Due that operates with 3.3V
  "Uno" means one in Italian and is named to mark the upcoming release of Arduino 1.0
  The Uno and version 1.0 will be the reference versions of Arduino, moving forward
  The Uno is the latest in a series of USB Arduino boards, and the reference model for the Arduino platform
  This is the new Arduino Uno R3. In addition to all the features of the previous board, the Uno now uses an ATmega16U2 instead of the 8U2 found on the Uno (or the FTDI found on previous generations)
  This allows for faster transfer rates and more memory
  No drivers needed for Linux or Mac (inf file for Windows is needed and included in the Arduino IDE), and the ability to have the Uno show up as a keyboard, mouse, joystick, etc
