What Is the NVIDIA Jetson Nano?

The NVIDIA Jetson Nano is part of NVIDIA’s Jetson family, designed for edge AI—processing data locally on devices to reduce latency and enhance privacy. Unlike cloud-dependent systems, the Nano brings AI capabilities to compact hardware, making it perfect for robotics, IoT, and computer vision projects. Its affordability set it apart at launch, competing with boards like the Raspberry Pi while offering CUDA-accelerated computing for machine learning tasks.

In 2025, the Jetson Nano remains relevant for educational purposes, legacy projects, and budget-conscious makers. Though NVIDIA has released more powerful successors (e.g., Jetson Orin Nano and Orin Nano Super), the Nano’s compatibility with NVIDIA’s JetPack SDK and its vibrant community keep it alive. However, stock can be limited on platforms like Amazon, so check availability or consider third-party sellers.

This review covers unboxing, setup, specs, performance benchmarks, project ideas, comparisons, and more to help you decide if the Jetson Nano fits your needs.

Unboxing the NVIDIA Jetson Nano Developer Kit

Opening the NVIDIA Jetson Nano box is exciting, revealing a sleek, professional package with NVIDIA’s signature green branding. Inside, you’ll find:

• Jetson Nano module: A credit-card-sized board with an integrated heatsink.
• Carrier board: Provides ports and connectivity.
• Power supply: 5V/4A barrel jack adapter.
• Quick start guide and warranty info.
• NVIDIA stickers: A fun bonus for enthusiasts.

You’ll need to supply a microSD card (64GB recommended), HDMI cable, and peripherals like a keyboard and mouse. This keeps costs low but requires budgeting ~$20-50 for extras. For testing, I used a 64GB SanDisk microSD card, a standard HDMI cable, and a USB keyboard/mouse combo.

The build quality is robust, featuring a quad-core ARM Cortex-A57 CPU, 4GB LPDDR4 RAM, and a 128-core Maxwell GPU delivering 472 GFLOPS. Connectivity includes Gigabit Ethernet, four USB 3.0 ports, HDMI 2.0, MIPI CSI camera interface, and GPIO pins compatible with Raspberry Pi hats. The passive heatsink handles light workloads, but heavy AI tasks may require a fan (available for ~$20 on Amazon).

Setup is simple: Attach the module to the carrier board, insert the flashed microSD card, connect peripherals, and power on.

Step-by-Step Setup Guide for the Jetson Nano

Setting up the Jetson Nano is user-friendly, thanks to NVIDIA’s JetPack SDK. Here’s how to get started:

1. Download JetPack SDK: Visit the NVIDIA Developer website and download JetPack 4.6.5 (the latest for Nano in 2025). It includes Ubuntu 18.04, CUDA, cuDNN, TensorRT, and more.
2. Flash the microSD Card: Use Balena Etcher or NVIDIA’s SDK Manager to flash the JetPack image. SDK Manager simplifies the process on an Ubuntu host PC. Insert the card into the Nano.
3. First Boot: Power on, follow the Ubuntu setup wizard to create a user account, and connect to Wi-Fi (requires a USB dongle, as the Nano lacks built-in wireless). Run sudo apt update && sudo apt upgrade to update the system.
4. Install AI Frameworks:
   • TensorFlow: pip install tensorflow
   • PyTorch: Use NVIDIA’s ARM64 guides.
   • OpenCV: Pre-installed, verify with import cv2.

Setup takes ~30 minutes. Use a high-speed microSD card (A1 or better) to avoid slowdowns. Ensure a stable 5V/4A power supply to prevent boot issues. Once running, the Ubuntu desktop is intuitive, and NVIDIA’s “Hello AI World” demos (e.g., object detection with SSD-MobileNet) showcase its capabilities.

Hardware Specifications Breakdown

The Jetson Nano’s specs are modest by 2025 standards but impressive for its price:

• CPU: Quad-core ARM Cortex-A57 @ 1.43 GHz, 64-bit, with NEON extensions for vector processing.
• GPU: 128-core NVIDIA Maxwell @ 921 MHz, delivering 472 GFLOPS (FP16) for AI inference.
• Memory: 4GB 64-bit LPDDR4 @ 1600 MHz, shared between CPU and GPU (a bottleneck for large models).
• Storage: microSD card slot (up to 256GB recommended).
• Connectivity:
  • Video: HDMI 2.0 (4K@60Hz), DisplayPort.
  • Networking: Gigabit Ethernet.
  • USB: 4x USB 3.0, 1x micro-USB (debugging).
  • Camera: MIPI CSI-2 (Raspberry Pi camera compatible).
  • Expansion: 40-pin GPIO, I2C, SPI, UART; M.2 Key E for Wi-Fi/Bluetooth.
• Power: ~5W idle, ~10W under load.

The Nano’s low power consumption makes it ideal for battery-powered projects like drones or robots. Its 0.5 TFLOPS (INT8) AI performance supports lightweight models like ResNet-50 but struggles with larger ones like GPT-2 without optimization.

Performance Benchmarks and Real-World Testing

I tested the Jetson Nano with JetPack 4.6 to gauge its 2025 relevance:

• CPU Benchmarks:
  • Geekbench 5: ~350 single-core, ~1200 multi-core (similar to 2018 smartphones).
  • Sysbench: ~1500 events/sec.
• GPU and AI Performance:
  • CUDA Matrix Multiplication: Showcases GPU’s advantage over CPU.
  • TensorRT Inference: ~20 FPS on ResNet-50 for image classification.
  • Object Detection: 10-15 FPS on 720p video with SSD-MobileNet.
• Real-World Tasks:
  • Computer Vision: Face detection with OpenCV and a USB camera achieves 30 FPS.
  • Machine Learning: Training a small MNIST model takes ~5 minutes/epoch; inference is near real-time.
  • Robotics: Handles basic ROS-based SLAM demos.

Thermals: The stock heatsink reaches 60-70°C under load. A $10 fan keeps it below 50°C. Limitation: The 4GB RAM limits large model training; quantization helps.

Practical AI Applications and Project Ideas

The Jetson Nano shines in hands-on projects. Here are some ideas with estimated costs:

1. Smart Home Security (~$150): Use a MIPI camera with YOLOv3 for intruder detection. Add facial recognition with dlib for personalized alerts.
2. Autonomous Robots (~$200): Pair with Arduino for motor control and use the Nano for vision-based navigation (e.g., obstacle avoidance).
3. Drone AI (~$300): Integrate with PX4 for object tracking in flight.
4. Healthcare Prototypes (~$100): Monitor vitals with sensors, using ML for anomaly detection.
5. Educational Tools: Run Jupyter notebooks to teach neural networks.

Sample Project: I built a plant monitoring system using a USB camera to detect wilting and send email alerts. It used OpenCV for image processing and TensorFlow for classification, running smoothly on the Nano. NVIDIA’s NGC offers pre-trained models to simplify development.
