GSM2 click is the simplest way to add GSM/GPRS communication layer to your project, for fast transmission of data, voice, and SMS. It features the Quectel quad-band M95 FA GSM/GPRS module that has an integrated TCP/IP protocol stack, serial multiplexer and enhanced AT commands. The board contains a quadrupole audio/microphone jack, an SMA antenna connector, as well as a SIM card socket.

GSM2 click is designed to run on both 3.3V and 5V power supply and communicates with the MCU over UART and the following pins on the mikroBUS™ line: INT, PWM, CS, RST and AN.

Note: the antenna is sold separately.

Quad-band frequencies

The M95 FA supports quad-band frequencies — GSM850MHz, GSM900MHz, DCS1800MHz or PCS1900MHz. The module can search these frequency bands automatically.

GPRS data transfer

The GPRS data uplink and downlink transfer is 85.6 kbps, which is high enough for multimedia messaging.

Power consumption

The power consumption of the M95 FA is really low — 1.3 mA in sleep mode.

For more information about the power consumption, see the module’s datasheet.

SMD jumper

There is one zero-ohm SMD jumper J1 used to select whether 3.3V (default) or 5V I/O voltage level is used. Note that, regardless of the logic level, the module requires a 5V power supply in both cases.
