GSM click is the easiest way to add GSM/GPRS communication to your device. The click features Telit's GL865-QUAD module. GSM click runs either on 3.3V or 5V power supply and communicates with the target microcontroller via UART interface.
Python Script Interpreter
It is possible to run an application from inside the module via the embedded Python Script Interpreter. Python is an easy-to-use programming language with clear syntax, and an interface that makes it simple to test small snippets of code.
The module has worldwide coverage - 850/900/1800/1900 MHz frequencies. GSM supports incoming and outgoing voice calls, sms and data communication (via GPRS)
Power saving modes
In power saving mode, the GL865-QUAD uses around 1.5 mA, and in power off mode it uses less than 5 μA. That is considerably low and ideal for IoT devices that rely on long battery life and low power consumption.
The Phonebook function allows storing of telephone numbers in the SIM memory. The capability of the Phonebook depends on the SIM version and its embedded memory. The SIM card socket is located at the back side of the click board.
Additional information about the GSM click
GSM click contains TXB0106 6-bit bidirectional voltage-level translator, for interfacing components that operate on different voltages from one another.
On-board SMA antenna connector as well as 3.5mm quadrupole earphone/microphone jack.
An onboard jumper (J1) is used to switch between 3.3V and 5V I/O voltage levels; by default, it's soldered in the 3.3V position.
Remote monitoring automation, asset tracking, surveillance and security, home automation systems, point of sales terminals etc.
