Overview
RM520N-GL is a 5G sub-6GHz module designed for IoT/EMBB applications. Adopts the 3GPP Release16 technology and supports 5G non-standalone (NSA) and standalone (SA) modes. Designed in an M.2 form factor, RM520N-GL is compatible with Quectel RM50xQ 5G module, LTE-A Cat 6 module EM06, Cat 12 modules EM12/EM12xR/EM121R-GL, and Cat 16 module EM160R-GL, which facilitate the migration from LTE-A to 5G. This industrial-grade module is for industrial and commercial applications.
The RM520N-GL series nearly covers all the mainstream carriers worldwide. Integrated GNSS receiver (supports GPS, GLONASS, BDS, and Galileo) greatly simplifies the product design and makes positioning capabilities quicker and more accurate.
Integrates built-in network protocol, and multiple industry-standard interfaces and supports multiple drivers and software functions (such as Windows7, 8, 8.1, 10, USB/PCIe drivers under Linux, Android. etc), which greatly expands its application in IoT and eMBB fields including Industrial Routers, Home Gateways, Set Top Box, industrial laptops, consumer laptops, Industrial PDAs, Rugged Industrial Tablet PCs, Cameras and Surveillance and Digital Signage.

Recommended Carrier Board
RM520N-GL adopts the standard M.2 Key B slot, which is compatible with the Waveshare's 4G/5G module with M.2 slot. The two commonly used carrier board for 4G/5G M.2 tests is listed below:
| Model | USB TO M.2 B KEY | M.2 TO 4G/5G HAT |
|---|---|---|
| Picture |  |
|
| Module Interface | M.2 port | M.2 port |
| Communication Interface | USB 3.0 | USB 3.0 |
| Application | 5G Dongle with access to Windows/Linux computers | 4G/5G Module designed for Raspberry Pi |
| OS | Windows/Linux | Raspberry OS/OpenWRT and other common Linux systems for Raspberry Pi |
USB TO M.2 B KEY
For more details about USB TO M.2 KEY, you can click here to see its hardware and user manual.
1. Hardware Connection
【Hardware Preparation】
- RM520N-GL × 1
- USB TO M.2 B KEY × 1
- 5G SIM card × 1
【Installation Guide】
Please refer to the following diagram to install the Nano SIM card (5G function should be enabled) and 5G module, and then install the heat sink, cooling silicone, and 5G antenna, see the following figure:
Using the USB TO M.2 B KEY board, the RM520N-GL 5G module can be plugged into a Linux host board such as a Windows computer/laptop, Raspberry Pi, or Jetson Nano via the USB 3.0 interface.
2. Connecting with Windows
2.1 Driver Installation in Windows
- Refer to the hardware connection above and connect the module to the Windows PC via USB TO M.2 B KEY.
- Install Windows-related drivers:
- RM520N-GL Windows NDIS Driver
- RM520N-GL Windows MBIM Driver
- Comparison of device manager recognition before and after driver installation (the following figure is a screenshot of the actual test under the Windows 10 system).
2.2 5G Network Speed Test
- Under the Windows system, it is recommended to use MBIM mode for 5G networking.
In general, after installing the driver according to the section 2.1 Windows Driver Installation, the computer device manager and network connection can be identified normally.
RM520N-GL network card, as shown in the following figure:
At this point, as long as the SIM card and band of the RM520N-GL 5G module that is connected to the RM520N-GL 5G module are available in the test area, the 5G network can be obtained automatically, as shown in the following figure:
- If the driver is installed and the
Quectel USB AT Port (COM)is identified, but the RM520N-GL NIC device is not identified, it is possible that the factory default of the 5G module is not MBIM mode or you have modified it to other modes in use. At this time, you can try to use SSCOM or QCOM serial assistant, openQuectel USB AT Port (COM)to send AT command to set to MBIM mode, the command is as follows:
AT+QCFG="usbnet",2 AT+CFUN=1,1
- After confirming that the module can normally access the Internet through 5G, we can use network speed test tools to test the speed of 5G Internet access, the following figure is a screenshot of the actual test with speed test software:
①The actual speed measurement results are affected by the network coverage, network congestion, and base station distribution.
②As the power consumption of the 5G module is large when testing the speed, the USB TO M.2 B KEY must be connected to a full-power USB3.0 interface for speed measurement, to avoid insufficient power affecting the speed measurement or reset the module to reconnect.
③If the NIC is identified as normal, the NET light is not on, and you cannot connect to the network, you can refer to FAQ.
2.3 GNSS Positioning Test
- Connect the passive GPS antenna to ANT3 of the module (corresponding to L1 of GNSS), note that the lettered side is facing down and the antenna is placed in an open outdoor test (note that GNSS positioning test cannot be performed in rainy weather).
- Then SSCOM or QCOM serial assistant opens
Quectel USB AT Port (COM)to send AT commands:
AT+QGPS=1 //Open GPS positioning AT+QGPSLOC=0 //Get GPS position
- With GNSS positioning enabled, you can open the
Quectel USB NMEA Port (COM)through SSCOM, QCOM serial assistant, or other positioning software to see the NMEA GPS positioning data output from this port, as shown below:
- GNSS positioning test completed, AT command can be sent to
Quectel USB AT Port (COM)to turn off GNSS positioning:
AT+QGPS=0 //disable GNSS positioning
3. Connect to other Linux main control such as Raspberry Pi/Jetson Nano
- Note: Linux system usage, same as M.2 TO 4G/5G HAT Raspberry Pi Linux Usage section.
M.2 TO 4G/5G HAT
- For more information about the M.2 TO 4G/5G HAT, you can click here to see its hardware and user manual.
- Connect to the Raspberry Pi Board
【Hardware Preparation】
- 5G SIM Card x 1
- RM520N-GL 5G HAT (with case) x 1 (kits included as shown below):
【Installation Guide】
- Use the double-plug USB 3.0 cable to connect the 5G HAT, and then connect the external 5V power to the Type-C power port of the 5G HAT. As shown below:
| Raspberry Pi Board | Pi 4B | Pi 3B/3B+ | CM4-IO-BASE |

FAQ
5G consumes a lot of power, and the host's USB interface might not provide enough power. Please use a USB double-plug cable to supply sufficient power to the module, as shown in the diagram.

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+QUIMSLOT? *Switch to SIM card 2 using the following commands: AT+QUIMSLOT=2 *Switch to SIM card using the following commands: 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 C corresponding dip switches are turned ON:

Question:What should I do if the NET light does not light up and I am not registered to the network?
- Please check whether the SIM card and the antenna are connected, and note that four antennas must be connected.
- Please check the hardware connection and use AT Log to check the network connection.
AT+CMEE=2 AT+CPIN? AT+COPS? AT+QCSQ AT+QENG="servingcell" AT+CGDCONT? AT+QNWPREFCFG="mode_pref"
