2. Soldering the headers
3. Plugging the board in
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.
4. Essential features
The underside of GSM3 click™ holds the SIM
card slot. Aside from that the click™ has the
following additional features: audio input/
output connection pad (for microphone
and earphones, can also be used as an FM
antenna). The STM800H module supports
Bluetooth so the click™ has an active 2.4GHz
antenna. A connector for an external GSM
antenna is also provided. Two indication
LEDs signal the operating and network
status of the module.

GSM3 click™ carries SIM800H, a quad-band
(850 / 900 / 1800 / 1900MHz) GSM/GPRS
module that transmits voice, sms and data
information. The board communicates with
the target board MCU through the following
mikroBUS™ lines: Tx and Rx (UART), RST
(reset), STA (status indicator), RTS, PWK
(PWRKEY, used to power on/down the module)
and CTS. GSM3 click™ is designed to use 3.3V
and 5V I/O voltage levels.
