WF864 Sengled Wifi Module
Overview
WF864 use for the MX1290 that is a highly integrated and high performance, low power consumption includes the ARM architecture M4F kernel processor and 1 x12. 4 GHZ WIFI single frequency subsystem and power management unit of SoC chip. Leaped up to 133 MH2 (MX1290) / 62.5 MH2 (MX1290V2), while the SoC integration with internal 256 KB SRAM, 512 KB ROM, it also contains UART, I2C, PWM, SPI and abundant peripheral interface, only need to provide the DC voltage of 3.3 V, a 40 MHZ crystals and Flash can work outside. Wi-fi subsystem contains 802.11 b/g/n rf, baseband, media access control (MAC) design, satisfy the application of low power consumption and high throughput.Based on intelligent hardware dedicated operating system at the same time the chip support – MiCO secondary application development, MiCO is a microcontroller based Internet operating system, based on the software, users can more easily control 1 ot intelligent device hardware

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; maintain at least a 20 cm separation between the EUT and the user’s body and must not transmit simultaneously with any other antenna or
- A label with the following statements must be attached to the host end product: This device contains FCC ID: 2AGN8-WF864.
- 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, a 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-WF864” or “Contains FCC ID:
2AGN8-WF864” 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:
- This device may not cause harmful interference, and
- 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.
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.
According to FCC KDB 996369 D01, For this device, OEM integrators is responsible for ensuring that the end-user has no manual instructions to remove or install module.
Canada Regulations
This device complies with Industry Canada’s licence-exempt RSSs. 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.
IC statement
The host product shall be properly labelled 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 be 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-WF864” or “where: 20888-WF864 is the module’s
certification number”.
A label with the following statements must be attached to the host end
product: This device contains IC: 20888-WF864.
