What is Jetson NANO? How to choose?

At the beginning of November 2020, NVIDIA released the Jestson Nano development kit with 2GB of memory, compared with the 4GB version of the Nano launched by NVIDIA in March 2019, the new model is different in terms of price, memory, camera, graphics card interface, etc., how to choose? Which one is more suitable?

The Jetson Nano module is a low-cost AI computer with the highest performance and power efficiency to run modern AI workloads, run multiple neural networks in parallel, and process data from multiple high-definition sensors simultaneously. Designed to support entry-level edge AI applications and devices, the comprehensive NVIDIA JetPack SDK includes accelerated libraries for deep learning, computer vision, graphics, multimedia, and more.

The 2GB Nano has become smaller in size, but it is not just a lite version, from the perspective of hardware arrangement alone, compared with the previous generation of products, not only the memory has been reduced by 2GB, but the price has been reduced a lot, the overall hardware layout, heat dissipation, and interface design have been greatly improved.

Memory

Jetson Nano 2GB has 2GB main memory, while the current Jetson Nano has 4GB main memory. The 2GB uses the same Tegra X1 module used by the Jetson Nano.

Price

In addition to some tweaks in memory, in terms of price, the $59 price of the 2GB version is 60% of the $99 price of the 4GB version, which is quite a 40% reduction at once.

Camera

Jetson Nano 2GB has 1 CSI camera interface, whereas Jetson Nano 4GB has 2 CSI camera interfaces.

Power supply

Jetson Nano 2GB is powered by the USB Type-C port.

  >Easy access to power supply devices: In recent years, almost all Android phones use a Type-C port for power supply, so most users have such      power supply devices at hand.
  >Stable power supply: Type-C provides 5V/3A power supply, which can fully meet the power supply of Jetson Nano 10W working mode.
  >No need to switch: any switching action is a hassle for novices. Now that the power supply method is unified, there is no need for additional            jumper switching and the chance of error is reduced.
Graphics card interface

The 4GB version provides 4 USB ports and a 1+1 (HDMP+DP) display interface, which has a wider range of application needs for developers, but for the vast majority of beginner users, too many interfaces are somewhat redundant. Therefore, the 2GB version has been modified to 3 USB ports and 1 HDMI display port, which is more practical.

Image package

The Jetson Nano 4GB image package does not work on the 2GB dev kit. Therefore, you need to choose different image packages according to different versions of Nano.

Operator interface

The Jetson Nano 2GB version has made a user-friendly improvement in the operation interface, in order to provide a more similar operation habit to Windows, the 2GB version provides the LXDE version of the operation desktop for the Ubuntu operating system. The user interface is more suitable for Windows 7/95, which is also the reason why the Jetson Nano 2GB design team hopes to reduce the strangeness of novices.

In addition, the 2GB version of the LXDE desktop is a lightweight application, which is the least resource-intensive of Ubuntu's classic desktops. When comparing the Unity desktop used by the Jetson Nano 4GB, the base resource takes up about 1.2GB of RAM, while the LXDE desktop only takes up 700MB of RAM, which is very important for the 2GB version and very thoughtful for the product designers. In addition, 2GB can run the same software as the Jetson Nano 4G or other members of the Jetson family.

We can also change the "language" to Chinese Simplified in the 2GB version of the operating environment, and install Chinese intelligent pinyin input method, WPS Office office software, and QQ chat tools, etc., so that it is also very easy to perform general daily paperwork, great!

If you make a more accurate comparison between the 4GB version and the 2GB version, you can find that the 4GB version provides richer interfaces, which is more suitable for experienced developers and can do a wider range of development work. The 2GB version has a lower cost, a more stable system, and easier operation, making it more suitable for a wide range of people, such as students and educators, who have a relatively weak computer base. It is a good teaching platform for teaching projects that do not require high computing power. Overall, the new product is more like an edge AI thing, where all the useless things are cut and the useful things are better.

Transportation, storage, use requirements for this LCD

In order to ensure the normal use of this product and prevent accidents such as electric shock or fire, please read and understand all the requirements and operating procedures before using this product. The following requirements are strictly observed:

1. The DC power supply required by this product is generated by the AC/DC power adapter, and the AC/DC power adapter should be kept away from the heat source and placed in a well-ventilated place.

2. AC power socket and AC power cord should pay attention to good grounding and can withstand sufficient current demand.

3. The input voltage of the DC power supply required by this product is +12V, the error is not more than +/-0.5V, and the current is determined according to the selected LED screen and the power of the whole machine.

4. Pay attention to good ventilation and heat dissipation, do not place in a closed non-thermal shell or box, and do not let direct sunlight or other heat sources bake.

5. Pay attention to avoid excessive humidity and excessive dust, so as to avoid circuit corrosion causing failure.

6. When assembling, pay attention to reserve a certain space to provide air convection on the board surface to dissipate heat, and prevent electrical conductors (such as fixed iron plates such as drive boards and high-voltage plates) and components on the board from contacting short circuits.

7. Pay attention to prevent the drive plate from bending and deforming due to additional pressure.

8. When assembling, pay attention to the correct electrical connection of the drive board, LED screen, button board and other components, select the correct LED screen working voltage (too low will show abnormal, too high may burn out the LED screen), check that it is correct before powering on.

9. The program on the driver board should match the corresponding LED screen.

10. Pay attention to electrostatic protection when assembling the board, and pay attention to avoid short circuit and static electricity on the hand to damage the board.

11. All input and output interfaces need to be operated in the case of power failure (plug and unplug connectors).

12. This product is suitable for general commercial use and household, the ambient temperature: -10~+40°C, relative humidity: ≤80%.

13. Unplug the power when not in use for a long time.
