MR2EHKB User Manual
Product Description
MR2EHKB module utilizes the Realtek RTL8710 chip, supporting IEEE 802.11b/g/n (2.4GHz
band 1T1R 150Mbps). The module has a total of 11 pins/pads, providing up to 9 GPIO ports.
Some GPIO pins can be multiplexed with other interfaces, such as a maximum of 7 PWM
interfaces, 2 serial ports, and 1 I2C interface.
The module is powered externally at 3.3VDC, with the external power supply needing to support a
maximum of 300mA current. It is recommended to use a switching power supply scheme of
1MHz or higher to provide better dynamic response. When selecting the power scheme, be
cautious of any noticeable drop or jitter in the 3.3VDC voltage during initial power-on, as this
could prevent successful module reset and startup. The module is primarily used in smart
home-related devices, including smart sockets, wall switches, light bulbs, and more.

FCC Statement
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.
This equipment 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.
Any changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.
2.2
This module has been assessed against the following FCC rule parts: CFR 47 FCC Part 15 C
(15.247, DTS). It is applicable to the modular transmitter
2.3
This radio transmitter 2AMUU-MWA05 has been approved by Federal Communications
Commission to operate with the antenna types listed below, with the maximum permissible gain
indicated. Antenna types not included in this list that have a gain greater than the maximum gain
indicated for any type listed are strictly prohibited for use with this device.
The concrete contents to check are the following three points.
１) Must use a PCB antenna with gain not exceeding those shown in the table below.
２) Should be installed so that the end user cannot modify the antenna
３) Feed line should be designed in 50ohm
Fine-tuning of return loss etc. can be performed using a matching network.
The antenna shall not be accessible for modification or change by the end user
2.4
The module complies with FCC Part 15.247 and apply for Single module approval.
2.5
Trace antenna designs: Not applicable.
The device must be professionally installed
The intended use is generally not for the general public. It is generally for industry/commercial
use.
The connector is within the transmitter enclosure and can only be accessed by disassembly of the
transmitter which is not normally required. the user has no access to the connector.
Installation must be controlled. Installation requires special training
2.6
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with a minimum distance of 20cm
between the radiator & your body. This transmitter must not be co-located or operating in
conjunction with any other antenna or transmitter.

Please notice that if the FCC identification number is not visible when the module is installed
inside another device, then the outside of the device into which the module is installed must also
display a label referring to the enclosed module. This exterior label can use wording such as
“Contains FCC ID: 2AMUU-MWA05”; any similar wording that expresses the same meaning
may be used.
2.9
Testing of the host product with all the transmitters installed – referred to as the composite
investigation test- is recommended, to verify that the host product meets all the applicable FCC
rules. The radio spectrum is to be investigated with all the transmitters in the final host product
functioning to determine that no emissions exceed the highest limit permitted for any one
individual transmitter as required by Section 2.947(f). The host manufacturer is responsible to
ensure that when their product operates as intended it does not have any emissions present that are
out of compliance that were not present when the transmitters were tested individually.
If the modular transmitter has been fully tested by the module grantee on the required number of
channels, modulation types, and modes, it should not be necessary for the host installer to re-test
all the available transmitter modes or settings. It is recommended that the host product
manufacturer, installing the modular transmitter, perform some investigative measurements to
confirm that the resulting composite system does not exceed the spurious emissions limits or band
edge limits (e.g., where a different antenna may be causing additional emissions).
The testing should check for emissions that may occur due to the intermixing of emissions with
the other transmitters, digital circuitry, or due to physical properties of the host product
(enclosure). This investigation is especially important when integrating multiple modular
transmitters where the certification is based on testing each of them in a stand-alone configuration.
2.10
Any company of the host device which installs this modular should perform the test of radiated &
conducted emission and spurious emission etc. according to FCC Part 15C: 15.247 and 15.209 &
15.207, 15B class B requirement, only if the test result complies with FCC part 15C: 15.247 and
15.209 & 15.207, 15B class B requirement. Then the host can be sold legally.
The host product manufacturer is responsible for compliance with any other FCC rules that apply
to the host not covered by the modular transmitter grant of certification. If the grantee markets
their product as being Part 15 Subpart B compliant (when it also contains unintentional-radiator
digital circuity), then the grantee shall provide a notice stating that the final host product still
requires Part 15 Subpart B compliance testing with the modular transmitter installed.
2.11
The host manufacture is recommended to use D04 Module Integration Guide recommending as
"best practice" RF design engineering testing and evaluation in case non-linear interactions
generate additional non-compliant limits due to module placement to host components or
properties.
2.12
This module is stand-alone modular. If the end product will involve the Multiple simultaneously
transmitting condition
or different operational conditions for a stand-alone modular transmitter in a host, host
manufacturer have to consult with module manufacturer for the installation method in end system.
Canada Statement
This device complies with Industry Canada’s license-exempt RSSs. Operation is subject to the
following two conditions:
(1) This device may not cause interference; and
(2) This device must accept any interference, including interference that may cause
undesired operation of the device.
Le présent appareil est conforme aux CNR d’Industrie Canada applicables aux appareils radio
exempts de licence. L’exploitation est autorisée aux deux conditions suivantes :
(1) l’appareil ne doit pas produire de brouillage;
(2) l’utilisateur de l’appareil doit accepter tout brouillage radioélectrique subi, même si le
brouillage est susceptible d’en compromettre le fonctionnement.
Please notice that if the ISED certification number is not visible when the module is installed
inside another device, then the outside of the device into which the module is installed must also
display a label referring to the enclosed module. This exterior label can use wording such as the
following: “Contains IC:24963-MWA05” any similar wording that expresses the same meaning
may be used.
