4G/3G/2G/GSM/GPRS/GNSS HAT for Raspberry Pi 4B/3B+/3B/2B/Zero/Zero W/WH and Jetson Nano/Ard/STM32,Based on SIM7600G-H,Support LTE CAT4 up to 150Mbps Wireless Communication etc (Globally Applicable)

I just connected it to my Raspberry Pi 4B via the GPIO pins and connected a USB from the Pi to the hat, and it just worked out of the box. GPS lock is acquired very quickly with the included antenna and I was ablt to connect to T-Mobile network without any issues.

Found using a software defined radio that the module transmits on 868 MHz regardless of how I configured it. I cannot use this module in the US without a license. It does not support LoRaWAN, and does not support changing LoRa parameters. This would be good for you if all you want is to be able to transmit data between two of your own devices, and don't want to mess with LoRa parameters.

The Waveshare 915M LoRa HAT for Raspberry Pi is a functional and straightforward device designed for basic LoRa communication. However, it's important to note a significant limitation: the lack of LoRaWAN support. This could be a deal-breaker for many, especially those seeking to integrate into broader LoRaWAN networks for IoT applications. While the device operates reliably for simple point-to-point LoRa communications, its inability to connect with LoRaWAN networks restricts its utility in more complex, connected projects. In essence, it's a working piece of hardware, but it may not meet the needs of those looking for LoRaWAN capabilities.

I had to replace my old USB device to get support for 4G LTE. This hat does the job, though I cannot get it to communicate directly via the GPIO interface despite the jumpers being set correctly and the serial has been enabled in raspi-config. The documentation is far from great. I am currently using it with the USB cable, gammu-smsd, and kalkun.

Perfect for adding LoRa capability to a Raspberry Pi. Do make sure there is a hub in you range before setting up. I already had a hub in the area so the LoRa set up was easy and the distance coverage enabled me to do a lot creative projects. I recommend this.

As other reviews have said, it doesnt support lorawan, and even though its a common chip, all comms are forced through UART or USB which means that most libraries don't have lorawan support. So its probably not what you want unless you are doing PtP links.

Easy to work with lots of free code easy to understand

Terrible documentation. Most videos online are for other hats, gateways, or products. The documentation is void of any actual information e.g. “First use [port] to connect then run your command to connect to gateway” like.... what? Where is the setup info? What is that port and where can I learn about the ports of this command. The other reviews about terrible docs, no instructions, and other issues are 100% the same garbage I’ve been dealing with. I’m now on my second because I needed to have a second node in my area and also to force one to act as a gateway? Good luck figuring out how to setup any of that. Waveshare is useless, most forums are filled with “that’s not an answer” types of replies, and after a couple weeks of searching, this past week has been extremely frustrating. I’ll be returning these as they are nearly impossible to get working or require some information that is buried in some place I haven’t checked. Best thing to do is find a video or setup guide online, then buy the product they’re using because these... are completely useless without documentation.

Pretty straight forward to get working with network-manager and network-manager-gnome installed. Also works with dhcpcd with some added libs and scripting i.e. not as straight forward. I only set it up on a pi so I can't comment about other devices. Powered from the pi supply alone it's close to the limit of what the supply could handle but still works. Requires doing some research to get working but it definitely works reliably once configured. I also pulled some GPS data from it through the GPIO UART without issue. Antennas are good quality. This is a kit with all the bits to get you going on cellular less the SIM card and services you will need from your carrier. Pretty neat device but lacking documentation with it to take it to where you have full connectivity you can use. You need to go find that info elsewhere in addition looking at to Waveshare's own site and put a little time into getting it working fully. If you are up to that it's worth it.

"Supports dial-up, telephone call, SMS, MMS, mail, TCP..." This device does not support MMS. It took me a while to find out why the device wasn't receiving my SMS. It's because my cell was sending MMS instead of a SMS. I sent an email to Waveshare and they confirmed that device doesn't support MMS. To fix my issue I had to change the configuration of my cell phone to send SMS instead. Luckily this configuration is per contact (per phone number). So if you're planning to use this device with your own cell phone that will work. But if you plan on using this device with other people that might be an issue since you won't have access to change their cell configuration.

Testing this weekend...:)

This product came with screw size M2, the standard screw size for Raspberry pi is M2.5 so if you have a board already fixed with the standard screw size, you will need to buy new screw set to fix it
