sengled W867 WiFi Module Introduction
WF867 is a Wi-Fi module, and the core processor is ESP8266. This module is designed for various applications such as LED Lighting control, Smart Devices Switch, Health monitoring, etc. ESP8266 with industry-leading low power and RF performance, supporting Wi-Fi IEEE802.11b/g/n agreements. ESP8266 integrates a Tensilica L106 32-bit RISC processor, which achieves extra low power consumption and reaches a maximum clock speed of 160 MHz. ESP8266 integrates the antenna switch, RF balun, power amplification amplifier, low noise amplifier, filter and power management. The WF867 with an internal PCB printing antenna and 18 Pins stamp hole patch package are easy installation.

FCC Certification Requirements.
According to the definition of mobile and fixed device is described in Part 2.1091(b), this device is a mobile device. And the following conditions must be met:
- This Modular Approval is limited to OEM installation for mobile and fixed applications only. The antenna installation and operating configurations of this transmitter, including any applicable source-based time- averaging duty factor, antenna gain and cable loss must satisfy MPE categorical Exclusion Requirements of 2.1091.
- The EUT is a mobile device; maintains at least a 20 cm separation between the EUT and the user s body and must not transmit simultaneously with any other antenna or transmitter.
- A label with the following statements must be attached to the host end product: This device contains FCC ID: 2AGN8-WF867.
- o comply with FCC regulations limiting both maximum RF output power and human exposure to RF radiation, maximum antenna gain (including cable loss) must not exceed:
- WIFI 2.4G(Tx: 2400MHz ~ 2483.5MHz): <4dBi
- This module must not transmit simultaneously with any other antenna or transmitter
- The host end product must include a user manual that clearly defines operating requirements and conditions that must be observed to ensure compliance with current FCC RF exposure guidelines.
For portable devices, in addition to the conditions 3 through 6 described
above, separate approval is required to satisfy the SAR requirements of FCC
Part 2.1093 If the device is used for other equipment that separate approval
is required for all other operating configurations, including portable
configurations with respect to 2.1093 and different antenna configurations.
For this device, OEM integrators must be provided with labeling instructions
of finished products. Please refer to KDB784748 D01 v07, section 8. Page 6/7
last two paragraphs: A certified modular has the option to use a permanently
affixed label or an electronic label. For a permanently affixed label, the
module must be labeled with an FCC ID – Section 2.926 (see 2.2 Certification
(labeling requirements) above). The OEM manual must provide clear instructions
explaining to the OEM the labeling requirements, options and OEM user manual
instructions that are required (see next paragraph). For a host using a
certified modular with a standard fixed label, if (1) the module’s FCC ID is
not visible when installed in the host, or (2) if the host is marketed so that
end users do not have straightforward commonly used methods for access to
remove the module so that the FCC ID of the module is visible; then an
additional permanent label referring to the enclosed module: “Contains
Transmitter Module FCC ID: 2AGN8-WF867” or“Contains FCC ID: 2AGN8-WF867” must
be used. The host OEM user manual must also contain clear instructions on how
end users can find and/or access the module and the FCC ID.
The final host/module combination may also need to be evaluated against the
FCC Part 15B criteria for unintentional radiators in order to be properly
authorized for operation as a Part 15 digital device. The user’s manual or
instruction manual for an intentional or unintentional radiator shall caution
the user that changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate the
equipment. In cases where the manual is provided only in a form other than
paper, such as on a computer disk or over the Internet, the information
required by this section may be included in the manual in that alternative
form, provided the user can reasonably be expected to have the capability to
access information in that form. 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. Changes or modifications not expressly approved by the manufacturer
could void the user’s authority to operate the equipment. 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 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.

Canada Regulations:
This device complies with Industry Canada’s license-exempt RSS. Operation is
subject to the following two conditions:
- This device may not cause interference; and
- This device must accept any interference, including interference that may cause undesired operation of the device.
CAUTION: The host product shall be properly labeled to identify the modules within the host product. The Innovation, Science and Economic Development Canada certification label of a module shall be clearly visible at all times when installed in the host product; otherwise, the host product must e labelled to display the Innovation, Science and Economic Development Canada certification number for the module, preceded by the word “Contains” or similar wording expressing the same meaning, as follows: “Contains IC: 20888-WF867” or “where: 20888-WF867 is the module’s certification number”.
