GSM Click is an add-on board in mikroBUS form factor which is a perfect solution for adding GSM/GPRS communication layer to your device. It features the Telit GL865-QUAD GSM/GPRS module which supports GSM/GPRS 850/900/1800/1900 MHz Quad-band frequency. The board contains a TXB0106 6-bit bidirectional voltage-level translator as well as a SIM card socket (SIM card not included). GSM Click communicates with the target microcontroller via seven mikroBUS lines (RX, TX, INT, PWM, CS, RST and AN). The board can use either 3.3V or 5V power supply, selectable via SMD jumper (soldered in 3.3V position by default). An LED indicates the presence of a power supply.

Additional features such as integrated TCP/IP protocol stack (including UDP, SMTP, ICMP and FTP), serial multiplexer, remote AT commands and more extend the functionality of the board.
