This Arduino UNO R3 is the original Arduino microcontroller board from Arduino Officials, based on Atmega328P. It has almost everything needed to support a microcontroller. Just simply connect it to a computer and power it via AC-to-DC adapter or use a battery to get started. In worst-case scenarios, when something wrong happens with the microcontroller, simply change the chip and you are to get started again.
The Original Arduino Uno Rev3 board is the first in a series of USB Arduino boards and the reference model for the Arduino platform. For an extensive list of current, past or outdated boards see the Arduino index of boards.
