GSM2 Click is an add-on board in mikroBUS form factor which is a perfect solution for adding a GSM/GPRS communication layer to your device. It features a Quectel M95 GSM/GPRS module which supports GSM 850MHz, GSM 900MHz, DCS 1800MHz or PCS 1900MHz quad-band frequencies with 85.6 kbps GPRS data transfer. It supports internet service protocols such as TCP/IP, UDP, FTP and PPP.

The board contains a quadrupole audio/microphone jack, an SMA antenna connector, as well as a SIM card socket (you must provide your own SIM card, of course). GSM Click communicates with the target microcontroller via seven mikroBUS lines (RX, TX, INT, PWM, CS, RST and AN).

This board can use either 3.3V or 5V power supply and I/O voltage levels, selected via SMD jumper (in 3.3V position by default). A green LED indicates the presence of power supply.
