The following precautions should be considered during designing with PCB antenna:

Do not place any electrical components or grounding in antenna area on main board and it’s

better to leave this area blank on PCB.

It is recommended to not place any electrical components within 10mm range of module

antenna and not design any circuit or bond copper on main board under this area.

Do not use the module inside any metal case or containers with metal painting.

Keep the antenna of wifi module next to the edge of main board (as shown in Fig 5) during

design of PCB to ensure better performance of antenna.

5. Reference Design

5.1. UART Interface Design

For devices with 3.3V power supply, you can directly connect the device UART port with

module UART port according to the illustration in Fig 12.

Fig 12 Circuit diagram (3.3V)

If your device is powered by 5V, you can refer to the circuit shown in Fig 13 or design your

own circuit for power conversion. The value of resistor can be adjusted according to actual circuit

design.

5.2. Power Supply Requirement

If an LDO is used to supply the module with 3.3V power, C1 capacitor can be considered to

be used with 10u-22u; If a DCDC is used to supply 3.3V power, C1 capacitor can be considered to

be used with 22uF.

It is recommended to supply the module with power higher than 400mA to ensure enough

power supply to the module and avoid power down during data transmission.

- 18 -

The module is designed with 2x 3.3V pins. You can power the module with either pin or both

pins.

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.

Note: This product 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 product 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 product 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.

Please take attention that changes or modification not expressly approved by the party

responsible for compliance could void the user’s authority to operate the equipment.

This equipment complies with FCC &IC RSS-102 radiation exposure limits set forth for an

uncontrolled environment. This equipment should be installed and operated with minimum

distance 20cm between the radiator & your body.

2.2 List of applicable FCC rules

FCC Part 15.247

2.6 RF exposure considerations

2.9 Information on test modes and additional testing requirements

Contact Hangzhou BroadLink Technology Co., Ltd. will provide stand-alone modular transmitter

test mode. Additional testing and certification may be necessary when multiple modules are used

in a host.

2.10 Additional testing, Part 15 Subpart B disclaimer

To ensure compliance with all non-transmitter functions the host manufacturer is

responsible for ensuring compliance with the module(s) installed and fully operational. For

example, if a host was previously authorized as an unintentional radiator under the Supplier’s

Declaration of Conformity procedure without a transmitter certified module and a module is

added, the host manufacturer is responsible for ensuring that the after the module is installed

and operational the host continues to be compliant with the Part 15B unintentional radiator

requirements. Since this may depend on the details of how the module is integrated with the

host, Hangzhou BroadLink Technology Co., Ltd.shall provide guidance to the host manufacturer

for compliance with the Part 15B requirements.

Note 1: This module certified that complies with RF exposure requirement under mobile or fixed

condition, this module is to be installed only in mobile or fixed applications.

A separate approval is required for all other operating configurations, including portable

configurations with respect to Part 2.1093 and difference antenna configurations.

This transmitter must not be co-located or operating in conjunction with any other antenna or

transmitter.

Note 2: Any modifications made to the module will void the Grant of Certification, this module is

limited to OEM installation only and must not be sold to end-users, end-user has no manual

instructions to remove or install the device, only software or operating procedure shall be placed

in the end-user operating manual of final products.

Note 3: Additional testing and certification may be necessary when multiple modules are used.

Note 4: The module operated only with the antenna which it is authorized.

The host product shall be properly labelled to identify the modules within the host product.

The ISED certification label of a module shall be clearly visible at all times when installed in the

host product; otherwise, the host product must be labelled to display the ISED certification

number for the module, preceded by the word "contains" or similar wording expressing the same

meaning, as follows:

Contains IC: 25062-BL3358P

This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject

- 20 -

to the following two conditions:

(1) this device may not cause interference, and

(2) this device must accept any interference, including interference that may cause undesired

operation of the device.

Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils

radioexempts de licence. L'exploitation est autorisée aux deux conditions suivantes :

(1) l'appareil ne doit pas produire de brouillage, et

(2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le

brouillage est susceptible d'en compromettre le fonctionnement.
