4. Essential features
GSM2 click™ with its Quectel M95 IC is ideal
for mobile devices. The Quectel M95 is a
quad-band GSM/GPRS engine that works at
frequencies of GSM850MHz, GSM900MHz,
DCS1800MHz or PCS1900MHz with 85.6
kbps GPRS data transfer. It supports
internet service protocols, such as TCP/IP,
UDP, FTP and PPP.

3. Plugging the board in
2. Soldering the headers
Once you have soldered the headers
your board is ready to be placed into the
desired mikroBUS™ socket. Make sure to
align the cut in the lower-right part of the
board with the markings on the silkscreen
at the mikroBUS™ socket. If all the pins are
aligned correctly, push the board all
the way into the socket.
Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder
the pins carefully.
Turn the board upside down so that
the bottom side is facing you upwards.
Place shorter pins of the header into the
appropriate soldering pads.
Before using your click™ board, make sure
to solder 1x8 male headers to both left
and right side of the board. Two 1x8 male
headers are included with the board in
the package.
1. Introduction
GSM2 click™
GSM2 click™ is an accessory board in
mikroBUS™ form factor. It’s a compact and
easy solution for adding a GSM module to
your design. It carries a Quectel M95 GSM
module, audio connector, SIM card socket as
well as an SMA antenna connector. GSM2
click™ communicates with target board
microcontroller via mikroBUS™ UART (Tx,
Rx), PWM, INT, AN, RST and CS lines. The
board is designed to use 3.3V and 5V I/O
voltage levels. LED diode (GREEN) indicates
the presence of a power supply.

6. SMD jumpers
There is one zero-ohm SMD jumper J1 used to
select whether 3.3V or 5V I/O voltage level is
used. Jumper J1 is soldered in 3.3V position by
default.
