For the first test, the following steps are required

1. Download the USB chip driver（Windows 10/11 usually installs the driver automatically）

2. Plug in the NANO development board – the driver should install automatically.

3. In the Arduino IDE, select the board type as "Arduino NANO".

4. Choose the correct COM port – you can find this in Device Manager on your computer. It corresponds to the port assigned to your NANO board.

5. As a first test, you can upload one of the example programs that come with the Arduino IDE.

Powerful: The Arduino Nano V3.0 Board Microcontroller Built with ATmega328P and CH340 chips instead of FT232, Improved new version CH340G Replace FT232RL, making it ideal for beginners
Seamless Compatibility: Fully compatible with Arduino Nano, supporting Arduino IDE, ISP programming and USB download. Works seamlessly with Windows, Mac, and Linux operating systems for a hassle-free experience.
Versatile I/O & Compact Design: Features 14 digital I/O pins (6 PWM outputs), 6 analog inputs, a 16MHz quartz oscillator, USB-C power socket, ICSP port, and reset button. Its compact, breadboard-friendly design ensures easy handling and integration.
Flexible Power Supply Options: Supports multiple power sources, including USB-C, 6-12V unregulated external power, or 5V regulated external power. The Nano board intelligently switches to the higher voltage source automatically—no jumper selection required.
