1、General Functions
The wireless module complies with IEEE 802.11 b/g/n standard and
it can achieve up to a speed of 65Mbps with single stream in 802.11n ,
54Mbps as specified in IEEE 802.11g, or 11Mbps for IEEE 802.11b to
connect to the wireless LAN.This compact module is a total solution for
a combination of Wi-Fi 802.11 b/g/n technologies with Microcontroller
Processor. The main control chip of this module is highly integrated
with Bluetooth low-power controller, with UART interface. It combines
Bluetooth protocol, BLE baseband, MODEM and BLE RF-IN chips. It also
supports GATT-based applications and MESH device applications based
on BLE users, and supports Bluetooth 5.0 low power consumption.
This compact module is a total solution for a combination of Wi-Fi
802.11b/g/n technologies with Microcontroller Processor. The module
is specifically developed for embedded system devices. Detailed

WIFI module has an independent power management system,
and the system provides a high quality of power supply for the whole
module. The Excellent matching circuit in RF-Front ensures that the
signal has minimal signal loss and radiation. Oscillator X1 provides the
IC U6 with the required oscillation frequency to enable the IC U6 to
work normally.IC U1 achieves energy-saving control through
continuous interactive learning of product operation environment
through algorithms.Flash U2、U8 is the external extended memory of
the IC U6、U1 for data storage.The IC U3 provides the interfaces for a
variety of peripherals (Timer, PWM, Interrupt, AD, the Debug) from the
module to the baseboard. Each peripheral that connects to the MCU
I/O pins can choose between two different I/O pin locations with the
provided flexibility in various applications.
Hereby, [Name of manufacturer], declares that this [type of
equipment] is in compliance with the essential requirements and other
relevant provisions of RE Directive 2014/53/EU. A copy of the full DoC
is attached.

(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.
NOTE: 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.
FCC& IC Radiation Exposure Statement:
This equipment complies with FCC and Canada radiation exposure limits set forth for
an uncontrolled environment. This equipment should be installed and operated with a
