Key Features of UNO R3:

ATmega328 processor running at 16MHz
CH340 Serial to USB converter
32KB Flash memory
14 Digital I/O
6 PWM shared with the digital I/O
6 Analog inputs that can also be used as digital I/O for a total of up to 20 digital I/O
1 Hardware serial port
5V Operation

The Uno R3 operates at 5V which can be supplied via an external power supply or through the USB port connection. The power source is selected automatically if both are available. If an external supply is used, it is recommended to use a supply between 7-12V. Higher input voltages will cause the on-board regulator to work harder and may cause it to overheat.

The attached board pin-out shows the most commonly used functions for the pins, but some pins can support other functions. Refer the the Arduino documentation for all possible functions for the pins.

This is Uno design which uses a DIP processor placed in a socket. The benefit to this design is that it is easy to replace the processor should the chip become damaged, but it does cost more than the SMD version that we also sell.

The board uses the CH340 chip for USB communications. If you have any issues with connecting to the board, you may need to download a driver. Just search for Arduino CH340 driver and you will find a number of sources for drivers depending on what Windows or Mac operating system you are using.

Pinout:

Watch a video walkthrough of this process

we’ll show you how to install CH340 drivers on multiple operating systems if you need them. The driver should automatically install on most operating systems. However, there is a wide range of operating systems out there. You may need to install drivers the first time you connect the chip to your computer’s USB port or when there are operating system updates.

Windows

Download the Windows CH340 Driver
Unzip the file
Run the installer that you unzipped
In the Arduino IDE when the CH340 is connected you will see a COM Port in the Tools > Serial Port menu, the COM number for your device may vary depending on your system.
