Features

• 40PIN GPIO extension header for connecting Jetson Nano
• Supports dial-up, telephone call, SMS, mail, TCP, UDP, DTMF, HTTP, FTP, etc.
• Supports GPS, BeiDou, Glonass, LBS base station positioning
• Onboard USB interface, to test AT Commands, get GPS positioning data, and so on
• Breakout UART control pins, to connect with host boards like Arduino/STM32
• SIM card slot, supports 1.8V/3V SIM card
• Onboard 3.5mm audio jack with earphone and mic support, for making telephone calls
• 2x LED indicators, easy to monitor the working status
• Onboard voltage translator, the operating voltage can be configured to 3.3V or 5V via jumper
• Baudrate: 300bps ~ 4Mbps (default: 115200bps)
• Autobauding baudrate: 9600bps ~ 115200bps
• Control via AT commands (3GPP TS 27.007, 27.005, and V.25TER command set)
• Supports SIM application toolkit: SAT Class 3, GSM 11.14 Release 99, USAT

Testing

• Insert the SIM card and earphone to the SIM7600X board, if you want to test the TF card slot, you can also insert a TF card to the card slot.
• Connect the USB interface of SIM7600X board to PC.

• The PWR indicator turns on after connecting
• Long-press the PWR button for 1, the NET LED turns on and became flashing after 10s. (If the NET indicator keeps solid, please check if the SIM card is workable)
• Check the Device Manager of PC, the several COM ports will be recognized:

• If the COM ports are recognized with an exclamation symbol, you should install the driver manually.
• Connect the DONGLE to Windows PC (Hereafter we use Windows 10 PC as example)）
• Open Device Manager—>Other Devices—>“SimTech, Incorporated”—>Update driver—>Browse my compute for driver software—>Choose the driver according to your OS—>Install it

FAQ

Question: NET light does not flicker after startup of SIM7600X, what should I do if the network is abnormal?

Answer: This situation may not be successfully connected to the network, you can follow the steps below: Firstly, check the hardware connection, check whether the antenna is properly connected, and check whether the +SIM card can be used to make normal calls and surf the Internet in mobile phones and other devices: After checking the hardware connection, the software can use these instructions: Check whether the SIM card is in good contact: AT+CPIN? Check if sim card is in good contact: AT+CNMP? Check the signal quality of the current environment: AT+CSQ Check operator access status: AT+COPS? Check networking status: AT+CPSI? Check that you have successfully registered to the network: AT+CREG?
