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
GNSS click™shares the same form factor of
Quectel’s L80 module which (used on GPS3
click™) and the same set of technologies:
automatic prediction of orbits from data stored
in internal ash (EASY™technology); and
adaptive adjusting of on/o time to balance
between positioning accuracy and power
consumption (AlwaysLocate™technology).
The module can also automatically switch
between the internal patch antenna and
external active antenna, keeping track of
positioning during the switching process.

GNSS click™carries Quectel’s L86 GNSS
module with a patch antenna along with an
external antenna connector. GNSS stands
for global navigation satellite system, a
term which encompasses both the United
States GPS and the Russian GLONASS
global positioning systems. The board
communicates with the target MCU through
mikroBUS™UART (TX, RX), CS (used here for
FON), and RST pins. The board uses a 3.3V
power supply only. A V_BAT connection pad
for a backup power supply is also available.

10. Disclaimer
GNSS click™has a connector for an external
active antenna that could be used alongside,
or instead of the patch antenna that’s
already on the module. To get one, search for
“GPS antenna” at www.mikroe.com/store
