GSM modules

GSM modules - text messages, HTTP communication and much more

The GSM modules produced today enable the use of almost all the advantages brought by the development of modern mobile networks. However, one may associate these advantages only with making phone calls or sending text messages, but the truth is that modern GSM offers many more interesting solutions. To be honest, although many modules still support voice calls, this feature is currently relatively rarely used in devices outside the mobile phone segment! This is because for the transmission of data, especially for control or measurement purposes, the ability to send and receive text messages and make Internet calls is much more useful. In the latter case, virtually all major protocols and modes of operation are available to you - including sending HTTP requests, low-level TCP and UDP connections, and file transfer support to/from FTP servers. Most importantly, virtually all GSM modules support AT commands, an easy-to-implement text protocol that can be used to successfully "manually" test the module via any terminal program that supports virtual serial ports (using the USB-UART converter).

GSM modules in all sizes

Our offer includes a wide range of GSM modules, from miniature circuits to be soldered on the target device's PCB to complete boards equipped with circuits, antennas and all necessary connectors and configuration elements, ready for immediate use in your devices and projects. To the first group belongs, for example, a perfect GSM / GPRS module - Fibcom G510 Q50-00, designed for surface mounting with the help of soldering pins located on all four sides of its socket and whose dimensions are only 20.2x22.2 mm. The finished GSM-GPRS Bluetooth module - namely h-nanoGSM v.1.08 - is only slightly larger. On the tiny 30x32 mm PCB there are (besides the module itself) two U. FL antenna connectors, a power button, a mini-USB socket, LEDs, a SIM card slot and pads for soldering a 2.54 mm gold pin connector. As if all that wasn't enough, there's even an integrated lithium-polymer battery charge controller on the same board.

GSM Shield for Arduino and Raspberry Pi

If your project is Arduino-based and you want to avoid any unnecessary wiring between the GSM module and the baseboard, you're sure to find a perfect Arduino GSM module among the shields we offer. All these GSM modules are mounted on a PCB whose structure is 100% compatible with Arduino hardware. A good example of such a GSM module (Arduino-compatible) is the DFRobot Shield GSM / LTE / GPRS / GPS - the board provides not only fast digital connectivity over the cellular network, but also access to current geolocation (thanks to the GPS receiver). However, if you’re not working on Arduino and you are looking for a Raspberry Pi GSM solution instead, we have the perfect module for you, too - Waveshare LTE GPS HAT. This Raspberry Pi GSM module is compatible in size with the Raspberry Pi Zero, and therefore with all other modules from the 3B+ / 3B and 2B series.
