Supports LTE-TDD/FDD, WCDMA, and GSM frequency bands
AT command control with multiple network protocols (TCP/IP, HTTP, FTP, etc.)
Compatible with Arduino UNO, Mega, Leonardo, and other controllers
The SIM7600G-H CAT4 4G/LTE Shield for Arduino brings high-speed wireless connectivity and global positioning to your Arduino projects. Designed with a standard Arduino pinout, it integrates seamlessly with popular boards like the UNO, Mega, and Leonardo, offering plug-and-play expansion for advanced IoT and communication applications.
This shield supports multi-band 2G/3G/4G networks, making it highly versatile for worldwide use. With LTE CAT4 technology, it delivers download speeds up to 150 Mbps and upload speeds up to 50 Mbps, ensuring fast, stable communication. Beyond internet access, it supports SMS, voice, and audio playback/recording, expanding its role from simple data transmission to full communication functionality.
Equipped with GNSS support, the SIM7600G-H enables precise location tracking using GPS, GLONASS, and BD satellite systems. Whether for mobile tracking, logistics, or remote monitoring, it provides a reliable, all-in-one solution for wireless data and positioning needs, making it ideal for both hobbyists and professional developers building IoT systems.
This board works fine for accessing the Rogers cell network. It probably works with other popular networks but I haven't tried that. I've been able to do voice calls and texts without difficulty. I haven't tried the GPS functions. The documentation, to the extent that there is documentation, is abysmal. It comes with no documentation and there are no links to documentation on the Robot Shop site. There is some sketchy documentation on the DFRobot site but it leaves *a lot* to be desired.
Some hints from experience: the long skinny black antenna is for the cell and it goes connector marked MAIN. The square antenna is for the GPS and it goes on the connector marked GNSS. Unless you are already familiar with those antenna connectors then get some advice online before you go to connect them: they are small, fragile, and easy to ruin. I found the Copilot AI invaluable for helping me get going with this board although it didn't know about the SIM socket. This board takes a Mini (that is, the largest size currently in use - called Mini for historical reasons) SIM card. To put the SIM card in you have to slide the metal top of the SIM socket up (if you look closely there are arrows showing open and close) at which point it opens like a door, you put the SIM card in close the door, then slide it down to lock. It took me some time to figure that out.
This board claims to work with an Arduino Uno so it comes with the TX/RX pins connected to D7/D8 and in theory you use bit banging on those pins to talk to the board. But the board defaults to 115,200 baud and the Uno can't bit bang at that rate so you have a problem right off the bat. But there are jumpers so you can disconnect TX/RX from D7/D8 and then run flyleads. In my case I used an Arduino Mega and ran flyleads to Serial3 which can do 115,200 and like that it worked fine.
USB on the Arduino will NOT power up this board. You need to have a decent power supply, 2 Amps is good, plugged into the barrel jack on the Arduino. You can use 12 Volts for this but then the regulator on the Arduino runs pretty hot. Something in the 7.5 V range is better.
In brief: good board, crappy documentation.

Great shield for wireless and GPS
It does exactly what I need: read GPS and enable access to all the wireless connectivity I could want. It uses either USB or a 7V+ pin input, which is something to be aware of. But as to the actual function, it worked straight away, the enclosed antennas were perfect.

Grand bouclier pour le sans fil et le GPS
Il fait exactement ce dont j'ai besoin: lire le GPS et permettre l'accès à toute la connectivité sans fil que je pourrais souhaiter. Il utilise soit une entrée USB, soit une entrée 7V + pin, ce dont il faut être conscient. Mais quant à la fonction réelle, cela a fonctionné tout de suite, les antennes fermées étaient parfaites.
