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.

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. 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, 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. ‐ 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.
