Waveshare SIM7600G-H

Raspberry Pi Hat with the LTE Cat 4 modem: SIM7600G-H

The Waveshare SIM7600G-H development kit has global support for LTE Cat-4 up to 150Mbps data transfer and can be easily attached to the Raspberry Pi 2, 3, 4 or Zero.

Quick Navigation


Get Started with the Waveshare SIM7600G-H

Insert the Monogoto SIM card at the bottom of the Waveshare HAT.

This guide explains how to connect the Waveshare HAT to the Raspberry Pit. It is also possible to connect your Windows, MaxOS or Linux machine to the Waveshare HAT directly allowing you to configure the SIM7600G-H modem without the need for a Raspberry Pi.

To do so, connect your computer to the micro USB port of the Waveshsare HAT and connect to the modem using PuTTY (Windows), minicom, screen or miniterm (Linux/MacOS). When using Windows, this driver is required.

Connect the LTE and GNSS antennas and add the Waveshare HAT to a Raspberry Pi. When using a Raspberry Pi Zero, the board should be connected right away with the help of the pogo pins. When using a Raspberry Pi 2, 3 or 4 you need to connect to the devices using a USB cable.

Power the Raspberry Pi and connect to it using SSH, or by connecting a keyboard and mouse.

The PWR LED of the Waveshare HAT lights up green, the NET LED starts blinking red.

Enable the hardware serial, allowing the Raspberry Pi to communicate with the Waveshare HAT. To do so, open the Raspberry Pi Software Configuration Tool by entering the following command in your terminal:

sudo raspi-config

Select: 3 Interface Options > P6 Serial Port

Answer <No> to “Would you like a login shell to be accessible over serial?”

Answer <YES> to “Would you like the serial port hardware to be enabled?”

Install minicom to be used as the tool to interface with the SIM7070G modem:

sudo apt-get install minicom 

Alternatives to minicom for Linux or MacOS are miniterm or screen, feel free to use your application of choice. When using Windows to connect to the Raspberry Pi, you can use PuTTY

Connect with the modem via port ttyS0 using minicom:

minicom -D /dev/ttyS0

Enter AT, if the modem responds with OK you successfully connected to the SIM7070G modem.

In case you don’t manage to open the ttyS0 connection or don't receive an OK:

  • Try rebooting the Raspberry Pi and try again

  • Try connecting to the SIMCom modem using USB port: ttyUSB2

  • Double check if the NET LED is blinking red. If not, the modem did not boot up

  • Be patient, it may take some time before the modem responds

Connect the SIM7600G-H to Monogoto

Visit the SIMCom SIM7600G-H documentation for a detailed guide on connecting the modem to Monogoto.

Test the connection by sending a PING

A PING test can be performed to test if the modem has an active data connection with a mobile network.

Send 5 PINGs to IP address with a timeout of 20 seconds.


If the connection is active, you will see 5 PINGs with a number representing the response time in milliseconds. Example response:

+CPING: 1,,64,104,255
+CPING: 1,,64,93,255
+CPING: 1,,64,145,255
+CPING: 1,,64,75,255
+CPING: 1,,64,157,255

Great work on connecting the SIM7600G-H to Monogoto! Have a look at the Things logs in the Monogoto Console to find more details about the established connection.
