7.2 Mounting XT65/XT75 to the Application Platform
There are many ways to properly install XT65/XT75 in the host device. An efficient approach is to mount the
XT65/XT75 PCB to a frame, plate, rack or chassis.
Fasteners can be M2 screws plus suitable washers, circuit board spacers, or customized screws, clamps, or
brackets. In addition, the board-to-board connection can also be utilized to achieve better support. To help you
find appropriate spacers a list of selected screws and distance sleeves for 3mm stacking height can be found in
Section 9.2.
When using the two small holes take care that the screws are inserted with the screw head on the bottom of the
XT65/XT75 PCB. Screws for the large holes can be inserted from top or bottom.
For proper grounding it is strongly recommended to use large ground plane on the bottom of board in addition to
the five GND pins of the board-to-board connector. The ground plane may also be used to attach cooling ele-
ments, e.g. a heat sink or thermally conductive tape. Please take care that attached cooling elements do not
touch the antenna pads on the module's bottom side, as this may lead a short-circuit.
To prevent mechanical damage, be careful not to force, bend or twist the module. Be sure it is positioned flat
against the host device.
