Windows CE 5.0/6.0 ARM, MIPSII Available
Mac OS X 10.3~10.8 N/A Available
Android 4.1 N/A Available
Notes: The chipset manufacturer has initiated different kind of software, please describe
detail requirements for better selection.
2.4. Design
Concerns:
2.4.1 Power supply:
1) The input power can be 5.0V DC , please mentioned it when place an order.
2) The external power shall be well designed with enough capacity.
2.4.2 Using semi-holes:
1） When the module is designed to be soldered on a main PCB board directly,
the area under the antenna end of the module should be keep clear of metallic
components, connectors, vias, traces and other materials that can interfere with the
radio signal. The recommended clear space requirements are refer to Fig 12 and Fig
13.
2） The module is not recommended using reflow oven process, hand soldering
is suggested.
2.4.3 Clear place to use the module:
The following drawing shows a recommended footprint which can be a reference for a
main PCB design.
The clear space requirement for onboard antenna is suit for either pin header or
semi-holes connection application.

FCC STATEMENT :
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that may
cause undesired operation.
Warning: Changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
FCC INFORMATION (additional)
OEM INTEGRATION INSTRUCTIONS:
This device is intended only for OEM integrators under the following conditions: The module must
be installed in the host equipment such that 20 cm is maintained between the antenna and users,
and the transmitter module may not be co-located with any other transmitter or antenna. The
module shall be only used with the internal antenna(s) that has been originally tested and certified
with this module. As long as 3 conditions above are met, further transmitter test will not be
required. However, the OEM integrator is still responsible for testing their end-product for any
additional compliance requirements required with this module installed (for example, digital
device emissions, PC peripheral requirements, etc.).
Validity of using the module certification:
In the event that these conditions cannot be met (for example certain laptop configurations or
co-location with another transmitter), then the FCC authorization for this module in combination
with the host equipment is no longer considered valid and the FCC ID of the module cannot be
used on the final product. In these circumstances, the OEM integrator will be responsible for
re-evaluating the end product (including the transmitter) and obtaining a separate FCC
authorization.
End product labeling:
The final end product must be labeled in a visible area with the following: “Contains FCC ID:
YWT-GWF-3B”.
Information that must be placed in the end user manual:
The OEM integrator has to be aware not to provide information to the end user regarding how to
install or remove this RF module in the user's manual of the end product which integrates this
module. The end user manual shall include all required regulatory information/warning as show in
this manual.
