Specifications of Nvidia Jetson Series

What should we pay attention to when deploying edge computers?

Several key factors need to be considered during deployment: network connectivity quality, security requirements, device management strategies, and how to ensure the system‘s ability to operate under extreme or unstable conditions.

What scenarios are these devices suitable for?

Edge computing devices are widely used in many industries and fields, including manufacturing (such as predictive maintenance), retail (such as smart shelf monitoring), medical care (such as remote patient monitoring), and autonomous vehicle. They can help process large amounts of data in real-time, enhance privacy protection, and improve overall system reliability.

Why choose edge computing?

Edge computing is particularly suitable for application scenarios that require low latency (such as real-time data analysis), high data processing capability, and security requirements. In some cases, transferring all data to a remote cloud center for processing is neither practical nor economical.

How are the power consumption and heat dissipation of edge computing devices controlled?

TWOWIN‘s product design fully considers energy efficiency and thermal management, using low-power processors combined with efficient cooling solutions (such as fan cooling, liquid cooling, etc.) to ensure stable operation under various environmental conditions.

How to ensure the security and privacy of edge computing data?

Our edge computing solution uses advanced encryption technology to ensure the security of data transmission,and processes sensitive information locally to reduce the risk of data leakage. Meanwhile, we adhere to industry standards such as GDPR to protect user privacy.

Can edge computing devices be remotely managed?

Yes, all edge computing devices featured by TWOWIN supportremote management and monitoring through the network. Users can easily access and control devices through web interfaces,APIs, or command-line tools.

What is edge computing?

Edge computing is a technical method for computing near data sources.It moves processing and analysis tasks from a central server or cloud toan edge device closer to the user for execution. This can reduce datatransmission latency, improve security, and alleviate the pressure on network bandwidth.

What is the definition of CSI interface?/How to open CSI camera?

Answer:

1. For pin definition, please refer to the user manual.

2. The development kit uses the CSI camera (cam0 and cam1):

①cd /home/nvidia/twork/jetcam-master/

②sudo python3camtest.py

Does HDMI support input signals? / Why is there no display when I use HDMI to VGA?

Answer:

1. The HDMI interface of the device only supports output, not input.

2. It is recommended to use a direct HDMI cable, and it is not recommended to use an adapter cable, as the adapter cable may cause abnormal output.

How to use CAN?

Answer: Test method: home/nvidia/twork/can_test/

Does it support socket can? / Does it have terminal resistor?

Answer: Devices that support socketCAN and smart box with CAN have built-in CAN terminal resistors

What is the pin definition of 232? / What is the serial port number of 232?

Answer:

Interface definition: The RS23 interface of DP9 interface is defined as: 2RX3TX5GND, the others are empty pins, other interface forms of RS485 can be seen in the wire

Serial port number: Different models of devices have different serial port numbers corresponding to the interfaces. You can check the user manual or follow the actual test.

What is the pin definition of 485? / What is the serial port number of 485?

Answer:

Interface definition: The RS485 interface definition of DP9 interface is: 1A2B5GND, the others are empty pins, other interface forms of RS485 can be seen in the silk screen

Serial port number: Different models of devices have different serial port numbers corresponding to the interfaces. You can check the user manual or follow the actual test.

How to check the status of gpio/how to call gpio?

Answer:

Ubuntu 18.04

sudo cat /sys/kernel/debug/gpio View gpio status

example:

D1 = gpio 258

sudo chmod 777 /sys/class/gpio/export

sudo echo 258 > /sys/class/gpio/export

sudo chmod 777 /sys/class/gpio/gpio258/value

sudo chmod 777 /sys/class/gpio/gpio258/direction

Sudo echo "out" > /sys/class/gpio/gpio258/direction #Set GPIO258 to output

sudo echo 0 > /sys/class/gpio/gpio258/value #Set GPIO 258 to output low level

sudo echo 1 > /sys/class/gpio/gpio258/value #Set GPIO 258 to output high level

sudo echo "in" > /sys/class/gpio/gpio258/direction #Set GPIO258 as input

Ubuntu 20.04

Sudo cat /sys/kernel/debug/gpio View gpio status

example:

D1 = gpio 448 (PR.05):

sudo chmod 777 /sys/class/gpio/export

sudo echo 448 >/sys/class/gpio/export

sudo chmod 777 /sys/class/gpio/PR.05/value #The difference from the 18.04 version is that the io number 448 is originally filled in here and now needs to be changed to PR.05

sudo chmod 777 /sys/class/gpio/PR.05/direction #Add GPIO 448

Sudo echo "out" > /sys/class/gpio/PR.05/direction #Set GPIO 448 to output

Sudo echo "in" > /sys/class/gpio/PR.05/direction #Set GPI0 448 as input

sudo echo 0 > /sys/class/gpio/PR.05/value #Set GPIO 448 to output low level

sudo echo 1 > /sys/class/gpio/PR.05/value #Set GPIO 448 to output high level
