### - reComputer J401 Carrier Board

The reComputer J401 carrier board is an advanced, open-source extension board for NVIDIA Jetson Orin Nano/ Orin Nano modules. It breaks out typical IO interfaces from the SoM, inlcuding 4x USB 3.2, HDMI 2.1, 2x CSI, 1x RJ45 for GbE, M.2 Key E for WiFi/BLE connection, M.2 Key M for storage expansion, CAN, and GPIO, Pre-installed JetPack 5.1.1 on 128GB NVMe SSD, and also supporting the latest JetPack 6 BSP , all for accelarating your solution to market in ease.

<p align="center">
<img src="./images/computer-vision.png" height="400" alt="computer-vision">
</p>

### - Heatsink with Fan

This Aluminum Heatsink offers essential, active, physical, and strong fan air cooling function for reComputer J401 carrier board, to avoid overheating and throttling problems while operating tough computing tasks. It is designed for continuous deployment, and can be customized to air flow speed through PWM function.


### - Aluminum Enclosure

The whole device with aluminum case is compact as 130mm x120mm x 58.5mm, which can be easily embedded into various scenarios from autonomous machine to industrial system supporting multiple installation modes such as desktop and wall mounting. We also provide comprehensive certifications such as ROHS, CE, FCC, KC, UKCA, ensuring your product ready-to-go for the market.

# Use NoMachine to remotely connect to the Jetson desktop

## Introduction

​ NoMachine is a remote desktop software that allows users to securely access and control computers from anywhere. It provides fast and smooth performance by using the NX protocol, enabling tasks such as working on files, running applications, watching videos, or playing games on a remote machine as if sitting in front of it. NoMachine supports multiple platforms including Windows, macOS, Linux, and mobile devices, and is often used for remote work, technical support, and collaboration.

![image-20250926160018342](/home/zibochen/data/wiki/reComputer-Jetson-for-Beginners/3-Basic-Tools-and-Getting-Started/3.10-Nomachine/images/image-20250926160018342.png)



## Installation on PC

**Step 1.**Installation Match the version of your PC system.

[Nomachine](https://www.nomachine.com/)

![image-20250926161736173](/home/zibochen/data/wiki/reComputer-Jetson-for-Beginners/3-Basic-Tools-and-Getting-Started/3.10-Nomachine/images/image-20250926161736173.png)

> Note:Here we will use the ubantu pc host for the demonstration.

https://download.nomachine.com/download/?id=1&platform=linux

![image-20250926162027354](/home/zibochen/data/wiki/reComputer-Jetson-for-Beginners/3-Basic-Tools-and-Getting-Started/3.10-Nomachine/images/image-20250926162027354.png)

**Step 2.** Install the client.

```bash
#INSTALL
cd /usr
wget https://web9001.nomachine.com/download/9.1/Linux/nomachine_9.1.24_6_x86_64.tar.gz
sudo tar xvzf nomachine_9.1.24_6_x86_64.tar.gz
rm nomachine_9.1.24_6_x86_64.tar.gz
sudo /usr/NX/nxserver --install

```

Other operations(optianal)

```bash
#UPDATE
cd /usr
sudo tar xvzf <pkgName>_<pkgVersion>_<arch>.tar.gz
sudo /usr/NX/nxserver --update
#UNINSTALL
sudo /usr/NX/scripts/setup/nxserver --uninstall
sudo rm -rf /usr/NX
```

## Installation on Jetson

**Step 1.** Download and install

```bash
wget https://web9001.nomachine.com/download/9.1/Arm/nomachine_9.1.24_6_arm64.deb
sudo dpkg -i nomachine_9.1.24_6_arm64.deb
```

After installation is completed, the following key information will be displayed:

![image-20250926160530003](/home/zibochen/data/wiki/reComputer-Jetson-for-Beginners/3-Basic-Tools-and-Getting-Started/3.10-Nomachine/images/image-20250926160530003.png)

If your Jetson is not connected to a display, additional configuration is required to use Remote Desktop properly.

**Step 2.** Check jetson's ip address

![image-20250926165250083](/home/zibochen/data/wiki/reComputer-Jetson-for-Beginners/3-Basic-Tools-and-Getting-Started/3.10-Nomachine/images/image-20250926165250083.png)

**Step 3.** We need to stop the system's graphics display manager and let NoMachine use the built-in virtual display service:

```bash
# 1. Stop the graphical display manager of the system
sudo systemctl disable gdm3 --now

# 2. Restart the NoMachine service
sudo /etc/NX/nxserver --restart
```

![image-20250926161036069](/home/zibochen/data/wiki/reComputer-Jetson-for-Beginners/3-Basic-Tools-and-Getting-Started/3.10-Nomachine/images/image-20250926161036069.png)Jetson is not connected to a monitor. PC can display the jetson graphical interface normally by connecting a nomachine to jetson.



> Note:If you want to connect a Jetson to a monitor to display images, you need to re-enable the gdm3 service.Run the following command:

```bash
# Re-enable the gdm3 service to start automatically at boot
sudo systemctl enable gdm3
# Start the gdm3 service immediately
sudo systemctl start gdm3
```

## Connection

Add->Add connection
