7.1. Power supply:
1) The input power can be 5.0VDC or 3.3VDC, please mentioned it when place an order.
2) The operation current of 5.0VDC power input will be different with that of 3.3V power
input. The external power shall be well designed with enough capacity.
3) Should 3.3VDC power be selected, please be sure it’s clean with low ripple; otherwise,
the EMI or RF performance might be deteriorated.
7.2. Using pin headers:
1) The pins can be less than 7 pins, but the VCC, UD-, UD+, GND must be applied for
USB interface communication.
2) Should the pin header connection be applied, please still keep enough metallic clear
space around the antenna end of the module, this gives better antenna performance
7.3. 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.
2) The module is not recommended using reflow oven process, hand soldering is
suggested.
7.4. Footprint design reference:
The following drawing shows a recommended footprint which can be a reference design for a main
PCB layout.

7.5. Soldering requirement:
The module is not recommended using reflow oven process, hand soldering is suggested.
If reflow oven process is selected, please keep good control on the soldering process. Otherwise
the flow air might blow components removing. A reference flow chaw likes as following:

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.
End Product Labeling
The final end product must be labeled in a visible area with the following:
“Contains FCC ID: YWTWF7601U7MX”.
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.
