1、General Functions
The wireless module complies with IEEE 802.11 a/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 802.11a/g, 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 a/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
802.11a/b/g/n technologies with Microcontroller Processor. The
module is specifically developed for embedded system devices.

signal has minimal signal loss and radiation. Oscillator Y1 provides the
IC U4 with the required oscillation frequency to enable the IC U4 to
work normally.Flash U2 is used for the external expansion memory.The
duplexer isolates the transmitting and receiving signals to ensure that
the receiving and transmitting can work normally at the same time.The
IC U4 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.

Caution: The user is cautioned that changes or modifications not expressly
approved by the party responsible for compliance could void the user's
authority to operate the equipment.
Second label must be place on the outside of the final device that contains
the following text:
“Contains FCC ID: 2ADAP-GRJWB05J2”
“Contains IC: 12478A-GRJWB05J2”
The FCC ID/IC ID can be used only when all FCC/IC compliance
requirements are met.

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.
