5G EVB User Guide 5G_EVB_User_Guide 7 / 36 1 Introduction This user guide describes detailed information about usage of the EVB (Evaluation Board) of Quectel 5G modules. The EVB is an auxiliary tool for engineers to develop and test these modules. 1.1. Applicable Modules Quectel 5G EVB is applicable to the following modules: Module Series Models 5G RG50xQ Series: RG500Q Series/ RG502Q-EA RG500U Series RG801H Series LTE-A EG512R-EA

5G EVB User Guide 5G_EVB_User_Guide 8 / 36 1.2. Safety Information The following safety precautions must be observed during all phases of the operation, such as usage, service or repair of any cellular terminal or mobile incorporating Quectel 5G modules. Manufacturers of the cellular terminal should notify users and operating personnel of the following safety information by incorporating these guidelines into all manuals of the product. Otherwise, Quectel assumes no liability for customers’ failure to comply with these precautions. Full attention must be paid to driving at all times in order to reduce the risk of an accident. Using a mobile while driving (even with a handsfree kit) causes distraction and can lead to an accident. Please comply with laws and regulations restricting the use of wireless devices while driving. Switch off the cellular terminal or mobile before boarding an aircraft. The operation of wireless appliances in an aircraft is forbidden to prevent interference with communication systems. If there is an Airplane Mode, it should be enabled prior to boarding an aircraft. Please consult the airline staff for more restrictions on the use of wireless devices on an aircraft. Wireless devices may cause interference on sensitive medical equipment, so please be aware of the restrictions on the use of wireless devices when in hospitals, clinics or other healthcare facilities. Cellular terminals or mobiles operating over radio signals and cellular network cannot be guaranteed to connect in all possible conditions (for example, with unpaid bills or with an invalid (U)SIM card). When emergent help is needed in such conditions, please remember using emergency call. In order to make or receive a call, the cellular terminal or mobile must be switched on in a service area with adequate cellular signal strength. The cellular terminal or mobile contains a transmitter and receiver. When it is ON, it receives and transmits radio frequency signals. RF interference can occur if it is used close to TV set, radio, computer or other electric equipment. In locations with potentially explosive atmospheres, obey all posted signs to turn off wireless devices such as mobile phone or other cellular terminals. Areas with potentially explosive atmospheres include fuelling areas, below decks on boats, fuel or chemical transfer or storage facilities, areas where the air contains chemicals or particles such as grain, dust or metal powders, etc.

The TE-A is connected to the EVB via BTB connectors J0701 and J0702. The interface allows customers to easily test the Wi-Fi function of the module or to develop applications with Wi-Fi function. The following two figures show the connection between FG50V-TE-A and EVB.

5G EVB User Guide 5G_EVB_User_Guide 32 / 36 4 EVB Operation Procedures This chapter introduces how to use the 5G EVB for testing and evaluation of Quectel modules. 4.1. Turn on the Module 1. Connect the module TE-A to the EVB via connectors J0101 and J0102. 2. Insert a (U)SIM card into the USIM1 card connector on EVB. 3. Use RF cable to connect the module TE-A to the EVB, and connect antennas to the EVB. 4. Connect the EVB to a 5 V/ 3 A power, then switch S0301 to ON. Then D0201 (ON/OFF indicator of the module’s power supply) will light up. 5. Press the S0202 (PWRKEY) for at least 500ms, then the module will be powered on and D0202 (operation indicator of the module) will light up. 4.2. Communication Via USB 4.2.1. Communication via USB Interface 1. Power on the module according to the procedure in Chapter 4.1. 2. Connect the EVB and a PC with USB cable through USB Type-C interface, and then run the driver disk on the PC to install the USB driver. For details about USB driver installation, please refer to document [1]. The USB port numbers can be viewed in Device Manager of the PC when the USB driver is installed, as shown below. Figure 28: USB Ports

5G EVB User Guide 5G_EVB_User_Guide 33 / 36 3. Install and then use QCOM provided by Quectel to realize the communication between the module and the PC. The following figure shows the COM Port Setting of QCOM: select the correct “COM Port” (USB AT Port, which is shown in figure above) and set correct “Baudrate” (e.g. 115200 bps). For more details about QCOM usage and configuration, please refer to document [2]. Figure 29: COM Port Setting Field on QCOM (USB AT Port Connection) 4.3. Firmware Upgrade Firmware of the module is upgraded via USB port by default, and there are two methods for the upgrade: emergency download and normal download. Please refer to the following procedures to upgrade firmware through the EVB. 4.3.1. Emergency Download 1. Install the firmware upgrade tool QFlash on PC. 2. Short-circuit the two pins of USB_BOOT interface (J0201). 3. Connect the EVB and the PC through USB Type-C cable. 4. Insert the DC power adapter and power on the module. 5. Upgrade the firmware with QFlash. Please refer to Quectel_QFlash_User_Guide for details about the use of QFlash.

5G EVB User Guide 5G_EVB_User_Guide 34 / 36 4.3.2. Normal Method 1. Turn on the module according to the procedure in Chapter 4.1. 2. Wait for the USB port to be found in Device Manage of the PC. Figure 30: USB Port in PC Device Manage 3. Open QFlash and upgrade the firmware. Please refer to Quectel_QFlash_User_Guide for the detailed procedure. 4.4. Reset the Module The reset option is only used in case of abnormality. For example, the software fails to respond for more than 5 s due to some serious problems. Long press the button S0201 (RESET) for more than 250 ms, and then release it to reset the module. 4.5. Turn off the Module There are two methods to turn off the module. ⚫ Turn off the module with AT command AT+QPOWD. This is a safer method. The module will log off from the network and save data before shutdown. ⚫ Turn off the module with PWRKEY button (S0301). Long press PWRKEY for at least 800 ms, then the module will be powered off.
