The Arduino Uno R3

A Microcontroller board based on the ATmega328.
This microcontroller has 14 digital I/O ports of which 6 can be used as PWM.
In addition, the ATmega328 has 6 analog inputs.

The Arduino in its entirety is controlled with a 16Mhz crystal and has a USB connector to program the ATmega328.
The Arduino Uno also has a power jack to power the board.
To put it simply the Arduino is a small microcomputer that gives an unprecedented amount of possibilities to your project

The Uno R3 differs from all other boards in that it does not use an FTDI USB to Serial converter. Instead it uses Atmega16U2 which is programmed as a USB to serial converter. The Ardruino Uno R3 is the most famous Arduino to date. The model dates from 2012, and has been the most popular all-rounder of many electronics hobbyists for years.

The ATMega328 is interchangeable with a new IC so you can use the board as a programming device, you can then process the Chip in your project and place a new one in the board and program it for your next project, just make sure you have a Chip back with a Bootloader already installed in the chip, We also have this chip with bootloader.
