Connecting to Jetson Nano

RM520N-GL 5G HAT is a 5G expansion board designed for Raspberry Pi. You can connect it to Raspberry Pi 4B/3B+/3B or the CM4 board. However, please note that the package includes a metal case that is only compatible with the Raspberry Pi 4B board. In the following sections, we will gradually explore the usage of the RM520N-GL module, covering hardware connections, software setup, 5G network dial-up internet, GNSS positioning, and programming control.

Hardware Connection

Hardware Preparation

  • 5G SIM card x 1 (5G is enabled)
  • RM520N-GL 5G HAT (with case) × 1 (the accessories is shown below)

RM520N-GL 5G-hardware.png

  • Connect the RM520N-GL 5G for Jetson Nano and the host computer with a USB 3.0 dual plug cable or USB 3.0 adapter as shown:

RM520N-GL 5G-hardware2.png

Loading USB Device Descriptors

To identify the module, the VID and PID information of the module needs to be added to the [kernel] file.

  • Check the VID and PID of the RM520N-GL:

RM520N-GL 5G for Jetson Nano-USB.png

  • Add VID and PID:
sudo su
sudo modprobe option
sudo sh -c 'echo "2c7c 0801" > /sys/bus/usb-serial/drivers/option1/new_id'
  • Successfully add PID and reboot Jetson Nano, and then USB0-USB4 device descriptors are shown below:
ls /dev/ttyUSB*

  • After resetting the module, the NET indicator is on, and you can use the following commands to check the network status (optional).
  • Use the following commands to get IP and set DNS:
sudo dhclient -v usb1
sudo apt-get install udhcpc
sudo udhcpc -i usb1
sudo route add -net usb1
  • After dialing, you can see that USB1 gets the IP by the following command:
ip route

Connect to Windows

Also, RM520N-GL 5G HAT can be directly connected to the USB 3.0 interface of a Windows PC with a USB 3.0 dual plug cable. In addition, 5V is required for the EXT PWR header for 5G communication. The connection effect is shown below:
RM520N-GL 5G for Jetson Nano-Win.png

The demonstration above doesn't show an external 5V power supply connected. To ensure the 5G module receives sufficient power, it's essential to externally connect a 5V power supply to the EXT PWR header on the HAT and switch to the EXT PWR.

Install Drivers

  • After connecting the 5G HAT to the computer through a USB 3.0 dual plug cable, there will be a series of devices without drivers installed on other devices:


  • Install Windows-related drivers:
  • Click setup.exe to install the driver. After the installation is complete, the device manager will generate the following devices:


MBIM Dial-up Networking

RM520N-GL series also can choose MBIM to the network, as shown below:

  • Open RM520N-GL AT port and send the following commands to the dial-up network:
  • After dialing and rebooting, the phone network card appears in the computer network connection interface, and the dial-up is successful.


Network Speed Test

RM50XQ Network Speed Test
  • Install speed testing software, such as Internet Speed Manager and other speed testing software, you can choose to download the speed test at www.speedtest.cn/pc/download.

About the Speed Testing

As there will be many inconsistencies between actual and laboratory conditions that will result in 5G speeds that are not ideally stable at 100MBPS, there are the following.

  • Base station distance, the closer to the 5G base station the better the signal and the faster the speed.
  • Base station load, the fewer people using it the faster it will be, and the slower it will be during peak commuting periods.
  • Number of base stations: due to the spectrum, an equal amount of 4G coverage requires double the number of 5G base stations.
  • Operator: you need to confirm your 5G card, and whether the speed is limited, you can regularly ask the operator to reset your network.
  • Indoor is worse than outdoor: building penetration attenuation, and indoor bypass attenuation.

PS: The current number of base stations still does not have good coverage, and the speed measurement is not quite the same in different locations.

GNSS Global Positioning

  1. Connect the passive GPS antenna to ANT3 of the module, note that the lettered side is facing down and the antenna is placed in the open outdoor area.
  2. Then use the AT port to send the AT command:
AT+QGPS=1        //Open GPS positioning
AT+QGPSLOC=0     //Get GPS position
AT+QGPS=0        //Close GPS position

3. Satellite data can be received by enabling the NMEA port to: RM50XQ-GNSS-02.png

GNSS antenna interface, hardware-related instructions, please refer to: Quectel_RM520N series hardware design manual




Windows Driver

The Windows driver of the Quectel series module cannot be installed together, for example, the MBIM driver should be uninstalled before installing the RNDIS driver.

As the 5G power consumption is relatively high, and the host computer's USB port may not be able to provide it with sufficient power, please refer to the USB dual plug cable to provide the module with sufficient power, as shown in the figure:



RM500U-CN and RM500Q-GL modules support installing two SIM cards at the same time, and you can enable one SIM card to work with AT commands:

*Select SIM card 1 by default, and check it with the following command:  
*Switch it to SIM card 2 with the following command:  
*Switch it to SIM card 1 with the following command:  
*Query whether the corresponding card slot identify the SIM card:  


  • If the corresponding SIM card can not be identified, it may because the DIP switch has not enable the corresponding module, please make the DIP switch corresponding to C turn on:
