Arduino Uno is the ideal board for getting started with electronics, through fun and engaging hands-on projects. This board is your entry to the unique Arduino experience: great for learning the basics of how sensors and actuators work, and an essential tool for your rapid prototyping needs. Arduino Uno Rev3 is the most used and documented board in the Arduino family.  Thanks to the lively and helpful community surrounding  the Arduino Uno, no one will find themselves without support.


Arduino Uno Rev3  is a microcontroller board based on the ATmega328P, an 8-bit microcontroller with 32KB of Flash memory and 2KB of RAM. 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.


  • Microcontroller: ATmega328P
  • Operating Voltage: 5V
  • Input Voltage: 7-12V (recommended) 6-20V (Limit)
  • Digital I/O Pins: 14 (6 are PWM)
  • Analog (ADC) Input Pins: 6
  • DC Current per I/O Pin: 20mA
  • DC Curret for 3.3V Pin: 50mA
  • Flash Memory: 32 KB
  • SRAM: 2KB
  • EEPROM: 1 KB
  • Clock Speed: 16 MHz


The 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). 

The ATmega328 on the 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 (referenceC header files).
