1. Introduction
The HLK-M30 module provides designers with a ready made component that provides a fully integrated solution for
applications, using the IEEE802.11 standard in the 2.4-2.5GHz ISM frequency band, including802.11b/g/n, can be quickly
and easily included in product designs. The modules integrate all of the RF components required, removing the need to
perform expensive RF design and test. Products can be designed by simply connecting sensors and switches to the
module IO pins or uart interface. The modules use MTK’s chip Wireless Microcontroller, allowing designers to make use of
the serial interface to connect with their device. Hence, this module allows designers to bring wireless applications to
market in the minimum time with significantly reduced development effort and cost.
The HLK-M30 is an embedded module based on the universal serial interface network standard,built-in TCP / IP
protocol stack, enabling the user serial port, wireless network (wifi) interface between the conversions. Through the
HLK-M30 module, the traditional serial devices do not need to change any configuration; data can be transmitted through
the Internet network. Provide a quick solution for the user’s serial devices to transfer data via Ethernet Also the HLK-M30
module have FCC modular approvals and is compliant with EU regulations.

FCC Warning
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: Any changes or modifications to this unit not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users
must follow the specific operating instructions for satisfying RF exposure compliance.
Note 1: This module certified that complies with RF exposure requirement under portable or mobile or fixed
condition, this module is to be installed only in portable or mobile or fixed applications.
A portable device is defined as a transmitting device designed to be used so that the radiating structure(s) of the
device is/are within 20 centimeters of the body of the user
A mobile device is defined as a transmitting device designed to be used in other than fixed locations and to
generally be used in such a way that a separation distance of at least 20 centimeters is normally maintained
between the transmitter's radiating structure(s) and the body of the user or nearby persons. Transmitting devices
designed to be used by consumers or workers that can be easily re-located, such as wireless devices associated
with a personal computer, are considered to be mobile devices if they meet the 20 centimeter separation
requirement.
A fixed device is defined as a device is physically secured at one location and is not able to be easily moved to
another location.
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: The device must not transmit simultaneously with any other antenna or transmitter.
Note 4: 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. Since this
may depend on the details of how the module is integrated with the host, Shenzhen HaiLingKe Electronic co., Ltd
shall provide guidance to the host manufacturer for compliance with the Part 15B requirements.
Note 5: FCC ID label on the final system must be labeled with “Contains FCC ID: 2AD56HLK-M30” or
“Contains transmitter module FCC ID: 2AD56HLK-M30”.
The transmitter module must be installed and used in strict accordance with the manufacturer's instructions as
described in the user documentation that comes with the host product. Shenzhen HaiLingKe Electronic co., Ltd is
responsible for the compliance of the module in all final hosts.
