DESCRIPTION
The Nano is a compatible version of the latest iteration of the Arduino Nano and is a miniature breadboard friendly version of the popular Uno. The small size allows you to place the Nano into your breadboard rather than jumping from the board over to a breadboard. The small size also makes the Nano useful for putting down on a solder type breadboard or building into a permanent circuit.
KEY FEATURES OF NANO :
- 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
- 8 Analog inputs of which 6 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 board operates at 5V which can be supplied via the Vin pin or through the USB port connection. The power source is selected automatically if both are available. If the Vin input 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.
Like all Arduino and compatible boards, it can be programmed using the Arduino IDE via the USB port.
OUR EVALUATION RESULTS:
These are nice clone assemblies with good build quality.
The Nano is one of our favorite boards for embedding into long-term projects as it has a good price/performance trade-off and despite its small size it still has a USB port so you don’t have to mess with an adapter to program the module through a TTL port.
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.

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.
