HET-WM300 User Manual
HET-WM300 Features
HET-WM300 is a highly integrated, low-power embedded WiFi module .The module includes
a full-featured WLAN subsystem powered by proven and mature IEEE 802.11n/g/b. The WLAN
subsystem integrates a WLAN MAC, baseband, and direct-conversion RF radio with integrated PA,
LNA, and transmit/receive switch, the maximum average output power is 18dBm. The module‘s
applications subsystem is powered by an ARM cortex-M4F CPU that operates up to
200MHz.Themodules supports an integrated 512KB SRAM,128KBmaskROM,and 2MB flash. The
module provides a full array of peripheral interfaces including SSP/SPI/I2S,UART,I2C,Gerneral
Purpose Timers and PWM, ADC,DAC, Analog comparator, and GPIOS.
The typical minimum application system schematic is shown in below, except the power
supply interface ,all other GPIOs can be used basing on user’s own applications and
requirements since the module provides a full array of peripheral interfaces including
SSP/SPI/I2S,UART,I2C,Gerneral Purpose Timers and PWM, ADC,DAC, Analog comparator, and
GPIOs. The power supply voltage range is from 3.0V to 3.6V, which should have 300mA load
ability at least, a dedicated low noise LDO is suggested to provide power supply for the module,
the module 3.3V inputs are connected together inner the module, at least one 100uF low ESR
capacitor should be placed as close as possible to the 3.3V pinout of the module. For detailed
information about the main chip functions ,please refer to 88MW300 datasheet.
Proprietary Information, No Dissemination or Use Allowed Without Prior Written Permission. All printed copies are considered Uncontrolled copies
unless the copies are stamped with “Controlled Copy” by Documentation Control.
Module Package information
Please refer to below module package dimension for PCB footprint building.
Module Placement Requirement
In order to get good RF performance, there should have no PCB under the antenna area of
the module, also the module should be placed on the side edge of the carrier or main PCB and
keep at least 15mm clearance out of any metal object at the left and right, refer to below
picture for module placement.

Module Firmware Feature
A rich software development kit(SDK) is provided for HET-WM300 series module, including
the RTOS operating system, TCP / IP protocol stack, rich peripheral driver library, totally reliable
encryption algorithm library, compatible with multi-protocol Cloud docking protocol library, a
rich variety of signals acquisition module and processing library, rich appliance control
algorithm library, standardization of storage technology, OTA upgrade, the main part of the
appliance control logic libraries. Users don’t need to understand the network communications,
cloud docking, Wi-Fi, operating system, encryption and other knowledge, users need only do
according to their specific product related customization of logic or function to complete the
development of the project. A significant reduction in IoT entry conditions, so that customers
can quickly develop products to enter the market. Software framework is shown in below.

FCC Statement
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 rec
eived, including interference that may cause undesired operation.
Changes or modifications not expressly approved by the party responsible for compliance could void the
user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, p
ursuant 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 fre
quency energy and, if not installed and used in accordance with the instructions, may cause harmful inter
ference to radio communications. However, there is no guarantee that interference will not occur in a part
icular installation. If this equipment does cause harmful interference to radio or television reception, whic
h can be determined by turning the equipment off and on, the user is encouraged to try to correct the inte
rference by one or more of the following measures:
‐ Reorient or relocate the receiving antenna.
‐ Reorient or relocate the receiving antenna.
‐ Reorient or relocate the receiving antenna.
‐Consult the dealer or an experienced radio/TV technician for help important announcement
Important Note:
Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
This equipment should be installed and operated with minimum distance 20cm between the radiator and
your body.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
Country Code selection feature to be disabled for products marketed to the US/Canada.
Proprietary Information, No Dissemination or Use Allowed Without Prior Written Permission. All printed copies are considered Uncontrolled copies
unless the copies are stamped with “Controlled Copy” by Documentation Control.
This device is intended only for OEM integrators under the following conditions:
1. The antenna must be installed such that 20 cm is maintained between the antenna and
users, and
2. The transmitter module may not be co-located with any other transmitter or antenna,
3. For all products market in US, OEM has to limit the operation channels in CH1 to CH11
for 2.4G band bysupplied firmware programming tool. OEM shall not supply any tool or
info to the end-user regarding toRegulatory Domain change.(if modular only test Channel
1-11)
As long as the three conditions above are met, further transmitter testing will not be required. However,
the OEM integrator is still responsible for testing their end-product for any additional compliance
requirements required with this module installed.
Important Note:
In the event that these conditions cannot be met (for example certain laptop configurations or co-location
with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID cannot
be used on the final product. In these circumstances, the OEM integrator will be responsible for
re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.
End Product Labeling
The final end product must be labeled in a visible area with the following" Contains FCC ID: 2ANR8-HET
-WM300 ".
Manual Information to the End User
The OEM integrator has to be aware not to provide information to the end user regarding how to install or
remove this RF module in the user’s manual of the end product which integrates this module.
The end user manual shall include all required regulatory information/warning as show in this manual.
