This is New Arduino Uno R3 is one of the latest versions of Arduino Uno with an onboard CH340 USB - serial converter chip. ArduinoUNoR3 provides you with a cheaper opportunity to get started with Arduino boards. The microcontroller model of this board is the same as the original one (Atmega328). The only difference between microcontrollers is the package. The original one has a DIP package but the clone one has an SMD package microcontroller. Arduino Uno r3 kit is more powerful as compared to the dip version.

Main changes from the older version:

• Two rows of the holes for the pins (Male and Female). So it can be connected with normal Female Jumpers.
• Additional 3 rows of the holes for wiring.
• Changes to the DIP package of ATMEGA328P to flat package.
• CH340G replace ATmega16U2

Specifications Of Improved Arduino Uno R3 With ATmega328 Microcontroller Development Board:

1. ATmega328-AU microcontroller with UNO Bootloader Installed.
2. USB Programming Facilitated by the CH340G.
3. USB-B Connector and cable included.
4. Input voltage - 7-15V.
5. 0-5V outputs with 3.3V compatible inputs.
6. 14 Digital I/O Pins (6 PWM outputs).
7. 6 Analog Inputs.
8. ISP Header.
9. 32k Flash Memory
10. 16MHz Clock Speed.
11. All SMD Construction.
12. R3 Shield Compatible

Features Of Cheap Version ArrduinoUnoR3 Programming Board Module:

• Main Changes from the older version:
• Add two rows of holes for the pins. So it can be connected with a normal jumper wires.
• Change the in-line package of ATMEGA328P to a flat package.
  
• CH340G Replace ATmega16U2
• Plug the UNO development board, the driver will be automatically installed.
• select the board UNO inside the die.
• Select the COM port, this can be in my computer queries, just inside your UNO port development board
• You'd better choose Arduino own routine procedures, burn them into the board

Package Includes:

• 1 x Arduino Uno SMD
• 1 X USB Cable
