This is improved Arduino Uno R3 is one of the latest versions of Arduino Uno with an onboard CH340 USB – serial converter chip. This provides you 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. It’s more powerful as compared to the dip version.
Specifications Of Arduino Uno:
- ATmega328-AU microcontroller with UNO Bootloader Installed.
- USB Programming Facilitated by the CH340G.
- USB-B Connector and cable included.
- Input voltage – 7-15V.
- 0-5V outputs with 3.3V compatible inputs.
- 14 Digital I/O Pins (6 PWM outputs).
- 6 Analog Inputs.
- ISP Header.
- 32k Flash Memor.y
- 16MHz Clock Speed.
- All SMD Construction.
- R3 Shield Compatible
- Main Changes from the older version:
- Add two rows of holes for the pins. So it can be connected with a normal Dubond line.
- Add 3 rows of holes for wiring.
- 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
