What actually the Arduino UNO R3 Board is?

To get started with coding and electronics, the Arduino UNO is the best board to be used. For a Rookie in the field, the UNO board is the most robust board to have an excellent start. In the worldwide family of the Arduino and Genuino, the most popular and documented board is the Arduino UNO R3 board.

The UNO board is a type of a microcontroller board which is based on the ATmega328. It allows more memory and higher transfer rates. The board has 14 digital i/o pins from which 6 pins can be used as PWM outputs, a USB connection, 6 analog inputs, a 16MHz quartz crystal, an ICSP header, a power jack, and a reset button. Just connect the board with a computer using a USB cable (you can also use an AC-to-DC adapter or battery to give power to the board) and you are good to go. The Arduino UNO R3 board has everything that needs to support a microcontroller.

Check the amazing features and specifications of the Arduino UNO R3 Board:

  • A first board in the series of Arduino USB boards
  • It has an input voltage of 7-to-12V
  • Contains 14 digital i/o pins (6 pins can be used as PWM outputs)
  • Based on the ATmega328 microcontroller
  • Has a flash memory of 32KB of which 0.5KB is occupied by the bootloader
  • Contains 2KB SRAM and 1KB EEPROM
  • A 16Mhz clock speed
  • Works with all the existing shields

The Arduino UNO R3 board is an open source hardware, but, however, you can build your own board using the files available on the Arduino website. The UNO board can be programmed with the IDE software. According to the microcontroller on your board, you can select from either Arduino or Genuino UNO from the board menu. The ATmega328 microcontroller on the Arduino Uno board makes the communication by using the original STK500 protocol.

How is the Arduino UNO R3 Board different to other boards?

The main difference between the Arduino UNO R3 board and other preceding boards is that the UNO board does not use the chip of the FTDI USB-to-serial driver. An ATmega16U2 microcontroller is featured with the board to be programmed as a USB-to-serial converter.

The Arduino UNO board comes with a poly fuse which is resettable. It protects the USB ports of your computer from the overcurrent and shorts. Remember that if you apply more than 500mA to the USB ports, then the poly fuse will break the connection automatically until you remove the overcurrent or short.

A thing to be noted for the Arduino UNO R3 Board:

For a proper installation of the Arduino UNO R3 board on some PCs, the Arduino 1.0 drivers are required. The R3 is tested and confirmed to be programmed in IDE older versions, though. If you are using the R3 board for the first time, it is advisable to install Arduino 1.0 on your machine.

Conclusion

The Arduino UNO R3 board is as amazing as the Arduino itself. It has all the configurations to be used with a microcontroller. You do not need drivers to be installed for the OS like Linux and Mac, however, you need INF files for Windows. For beginners, there is no other board better than the Arduino UNO R3. And for the pros in electronics, the board can be a great companion to support the microcontrollers and creating complex coding.
