Step 1: Prepare Your Jetson Nano

Before you make any physical connections, ensure your Jetson Nano is ready to go:

Install the Jetson Nano Operating System: If you haven’t done so yet, you will need to install an operating system onto your Jetson Nano. The recommended OS is Ubuntu 18.04 for Jetson. This can be achieved by downloading the NVIDIA Nano image and flashing it onto a microSD card using a tool like Etcher.
Power the Jetson Nano: Connect your Nano to a suitable power supply and ensure it’s booted up.

Step 2: Connect the Jetson Nano to Your Laptop

With your Jetson Nano powered and ready, follow these steps to connect it to your laptop:

Use the Micro-USB Cable: Connect one end of the Micro-USB cable to the Jetson Nano and the other end to an available USB port on your laptop.
Ensure the Jetson Nano is Recognized: Your laptop should recognize the Jetson Nano as an external device. On Windows, you can confirm this through the Device Manager, while Mac users can check under System Report.

Step 3: Enable SSH for Remote Access

Setting up SSH (Secure Shell) will allow you to access your Jetson Nano from your laptop without needing to use a direct connection every time. Here’s how to enable SSH:

Open Terminal on Jetson Nano: If you have a monitor connected, you can use the terminal directly on the Nano.
Install SSH:
bash sudo apt-get install openssh-server
Start SSH Service:
bash sudo systemctl start ssh
Ensure SSH Starts on Boot:
bash sudo systemctl enable ssh
Find the Jetson Nano’s IP Address: In the terminal, run:
bash ifconfig
Look for the IP address associated with the network connection (usually eth0 for wired or wlan0 for wireless).

Step 4: Connect to Jetson Nano from Your Laptop

Now that SSH is enabled, it’s time to connect to your Jetson Nano from your laptop.

Open Terminal on Your Laptop: Use the terminal application if you’re on macOS or Linux. For Windows, you can use a terminal emulator like PuTTY.
Use SSH Command: In the terminal, type the following command:
