Notes:
TX or WPS pin is internally pulled up with an onboard 4.7K ohm resistor to 3.3VDC .It is low level
(can be connected to ground) activated.
LED outputs 3.3V blink signal, the LED operation current is limited via the 330 ohm resistor.
If the onboard and external LEDs must be used simultaneously, proper LEDs’ operation current
must be considered, If necessary, the internal onboard LED can be removed while ordering.

3.6 Ordering information
Since there are many different types of pin header might be used, such as: straight pin; 90 degree
bend pin; long pin; short pin…, please mention the detail requirement of the pin header when
ordering. It can be mentioned by part number or by descriptions.
4 Agency Approval
CAUTION:
This module must be installed and operated in accordance with provided instructions and the antenna used for this
transmitter must be installed to provied a separation distance of at least 20 cm from all persons and must not be

Special Instructions:
Since the 5.0GHz operating current is High, in order to ensure that products -10 º C to +50 º C working
properly, must be added the heat sink;
If the customer wants to have a better product performance, it is necessary to replace the heat sink thermal
performance better (The thicker the larger the area the better the thermal performance).

FCC Statement
Federal Communication Commission Interference Statement
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 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 Caution:
Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.
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.
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This transmitter module must not be co-located or operating in conjunction
with any other antenna or transmitter.
This End equipment should be installed and operated with a minimum distance of 20
centimeters between the radiator and your body.
IMPORTANT NOTE:
In the event that these conditions can not be met (for example certain laptop
configurations or co-location with another transmitter), then the FCC authorization is no
longer considered valid and the FCC ID can not 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: YWTWF55724MX”.
Manual Information to the End User
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.
