Working with Jetson Nano
RM520N-GL 5G HAT is a 5G expansion board designed specifically for Raspberry Pi, which you can connect to a Raspberry Pi 4B/3B+/3B, or a CM4 board. But note that the kit includes a metal case, which is only suitable for the Raspberry Pi 4B motherboard. Below, we will gradually use the RM520N-GL module step by step from several aspects, including hardware connection, software settings, 5G network dial-up internet access, GNSS positioning, and programming control.
Hardware Connection
Hardware Preparation
- 5G SIM card x 1 (5G function must be enabled)
- RM520N-GL 5G for Jetson Orin × 1
- Connect the RM520N-GL 5G for Jetson Orin to the host using a dual-headed USB 3.0 data cable or a USB 3.0 adapter, as shown in the figure:

- Test usb1 networking status
ping -I usb1 www.baidu.com
Working with Windows
The RM520N-GL 5G HAT can also be directly connected via a USB cable to link the module's USB 3.0 interface with the USB 3.0 interface of a Windows computer. Additionally, an external 5V power supply needs to be connected to the EXT PWR interface on the board to ensure sufficient 5G communication power. The connection result is similar to the following image:
Install Driver
- After connecting the 5G HAT to the computer via a dual-headed USB3.0 data cable, a list of devices without installed drivers appeared under Other devices, similar to the following:
- Install Windows-related drivers:
Method 1: Install Manually
- Download RM5X0 driver file
- Ensure that the module has been properly powered on → Open Device Manager → Other Devices → "the outermost folder after driver decompression" → Update driver → Browse my computer to find driver files → Select the path where the driver files are stored based on the system ->Installation complete.
- For more detailed steps, please refer to RM5X0 driver installation video
Method 2: Automatic Installation
Download RM520N-GL Windows NDIS driver
- Click on setup.exe to install the driver, and after installation, the device manager will generate an unknown device similar to the figure below (taking RM500U as an example):
MBIM Dail-up
RM520N-GL series also can choose MBIM to surf the Internet, as shown below:
- Open RM520N-GL AT port, and send the following command to dial up:
AT+QENG="servingcell" AT+QCFG="usbnet",2 AT+CFUN=1,1
- After dialing and restarting, the mobile network card appears on the computer network connection interface, and the dialing is successful.
Networking Speed Test
- Install the testing software. You can choose to download and install speed testing software on your own.
About Measurement Speed
Due to many inconsistencies between actual and laboratory conditions, the 5G speed cannot be ideally maintained at 100MBPS. The following points:
- Base station distance, the closer you are to the 5G base station, the better the signal and the faster the speed;
- Base station load, the fewer people use, the faster the speed will be, and the commute will be slower during peak hours;
- Number of base stations: Due to the spectrum relationship, the same amount of 4G coverage requires double the number of 5G base stations
- Operator: You need to confirm whether your 5G card is speed-limited, you can periodically ask the operator to reset your network
- Indoors are worse than outdoors: building penetration loss and indoor diffraction loss
PS: The current number of base stations still does not have good coverage, and the speed measurement in different locations is not the same.
GNSS Global Positioning
1. Connect the passive GPS antenna to the ANT3 interface of the module, note that place with printed side facing downwards, and place the antenna outdoors in an open area.
2. Then use the AT port to send AT commands:
AT+QGPS=1 // Turn on GPS positioning AT+QGPSLOC=0 //Get GPS positioning AT+QGPS=0 //Turn off GPS positioning
3. Open the NMEA port to receive satellite data:
