01-Jetson Board Introduction
1. What Is a Jetson Board?
NVIDIA Jetson boards are compact edge AI computers. They run Linux, support GPU acceleration, and are built for robotics, vision, and AI inference workloads.
Compared with a microcontroller, Jetson can run full operating systems and AI frameworks. Compared with a desktop GPU PC, Jetson is lower power and designed for embedded deployment.
2. Why Jetson Orin Nano?
Jetson Orin Nano is a common entry point for:
- Learning CUDA and TensorRT on embedded hardware
- Building camera-based AI projects
- Running ROS/ROS 2 with onboard acceleration
3. Development Kit Variants
The main difference between the Jetson Orin official development kit and the SUB development kit is that the official kit does not include a power switch button.

4. Software Stack You Will See in HH-101
In the next setup lessons you will work with:
- JetPack (NVIDIA software bundle for Jetson)
- Ubuntu on the target board
- SDK Manager on a host machine
- CUDA, TensorRT, and related runtime components
