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)
- 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:
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:
lsusb
- 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*
RNDIS Dial Networking
- Enter minicom:
sudo apt-get install minicom sudo minicom -D /dev/ttyUSB2
- Send the following commands for RNDIS dial networking in minicom:
AT+CPIN? AT+QCFG="usbnet",3 AT+CFUN=1,1
- After resetting the module, the NET indicator is on, and you can use the following commands to check the network status (optional).
AT+QENG="servingcell"
- 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 0.0.0.0 usb1
- After dialing, you can see that USB1 gets the IP by the following command:
ip route
ping -I usb1 www.baidu.com
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:
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:
AT+QENG="servingcell" AT+QCFG="usbnet",2 AT+CFUN=1,1
- After dialing and rebooting, the phone network card appears in the computer network connection interface, and the dial-up is successful.
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
- 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.
- 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:

Different operators have different APNs, so it's important to distinguish and set them correctly. The configuration steps for some operators are shown below:
*China Mobile: AT+CGDCONT=1,"IPV4V6","CMNET" *China Unicom: AT+CGDCONT=1,"IPV4V6","3GNET" *China Telecom: AT+CGDCONT=1,"IPV4V6","CTNET" *AT&T: AT+CGDCONT=1,"IPV4V6","PHONE" *Vodafone: AT+CGDCONT=1,"IPV4V6","portalnmms *Add username and password: AT+QICSGP=1,1,"Your_apn"," Username "," Password ",1
There are the following dialing types:
AT+QCFG="usbnet",0 The drive type is NDIS(QMI); AT+QCFG="usbnet",1 The drive type is ECM; AT+QCFG="usbnet",2 The drive type is MBIM; (RM5XXQ support) AT+QCFG="usbnet",3 The drive type is RNDIS; AT+QCFG="usbnet",5 The drive type is NCM.
Please refer to the following document for detailed instructions:
Network card dial-up user guide
- No, currently all the cellular modules on the shelves require base station communication
- Cellular modules are nodes and cannot be used as base stations. They need to bridge communication through base stations and cannot communicate point-to-point
- For example, the RM500U-CN 5G HAT A module Raspberry Pi dial-up Internet access, after connecting to the base station, you can use TCP, MQTT, email or WeChat to communicate with B Raspberry Pi

By default, it is turned off. If support is required, a customized version is needed. If VoLTE functionality is needed, it is recommended to use the SIM8XXX module, which is turned on by default or can be turned off with commands
{{{5}}}
RM520 and other cellular modules that support positioning can support up to 1Hz. If you want faster speeds, you can consider dedicated positioning modules
{{{5}}}
Hardware
Please connect to ANT3, which is the antenna interface for positioning function
- The RM530N-GL has additional mmWave frequency band, and other functions are the same as those of the RM520N-GL
- The RM530N-GL currently does not have Verizon or AT&T certification. If you need these certifications, please select RM520N-GL
- No, it may come into contact with metal cover during storage and transportation, which will not affect its function at all. If you encounter any issues with use, please feel free to contact customer service at any time
- To ensure the quality of the module, each module is tested before shipment. During the testing process, it is inevitable that the module may be slightly touched, so there may be some traces
The power consumption of 5G is relatively high, and the host's USB port may not provide enough power. Please use a USB double-headed cable to supply adequate power to the module, as shown in the figure:
As RM500U-CN and RM500Q-GL modules support simultaneous access to two SIM cards, dual-card single standby, can be switched to enable one of the SIM cards to work through the AT command:
*SIM card 1 is used by default, you can use the following commands to check: AT+CMEE=2 AT+QUIMSLOT? *Switch to SIM card 2 using the following command: AT+QUIMSLOT=2 *Switch back to SIM card 1 using the following command: AT+QUIMSLOT=1 *Query whether the corresponding card slot identifies the SIM card: AT+CPIN?
If the corresponding SIM card is still not recognized, consider that the dip switches do not enable the corresponding module, please see if C corresponding dip switches are turned ON:
There is no sequence, please connect it nearby, align it with the interface and press it in. You can refer to IPEX1-IPEX4 adapter cable installation steps
