1、Product Overview
MM3U21150Z wireless module is a fully functional, highly integrated, low power
consumption dedicated Wi-Fi & Bluetooth module for the Internet of things. It
supports IEEE802.11 b/g/n protocol, also embedded IPV4, TCP, UDP, DNS, HTTP and
other complete network protocol, so that the terminal in the Internet of things
applications more reliable, convenient and easy to use.
MM3U21150Z core chip adopts the MT7697N single chip scheme of Media corp.
The chip is highly integrated with CPU, PMU, RAM, T/R SW, LNA, PA and other major
parts, thus greatly reducing the power consumption of the whole machine. The module
adopts the integrated three-dimensional metal antenna design, which can not only
reduce the cost of the antenna for customers, but also save the assembly space of the
antenna, greatly reduce the area of the board, and make the product more competitive.
At present, the module provides a complete serial port interface function to
communicate with the device, and can connect the cloud and the device through the
serial port and the mobile client.
The module has the following characteristics:
Support IEEE 802.11 b/g/n protocol
Supports 20MHz and 40MHz bandwidth in the 2.4ghz band
Support bluetooth BLE 4.2
The module has a built-in metal antenna
Low power listening mode
Both up and down theoretically support a connection rate of 150Mbps
Support encryption protocols: WFA, WPA, WPA2, WPS2.0
Support IPV4, TCP, UDP, DNS, HTTP and other network protocols

3、Radio frequency characteristics
3.1 transmission and reception characteristics
Support IEEE 802.11 b/g/n standard;For parameters such as transmitting power,
receiving sensitivity, EVM and distribution, a more stringent standard than the IEEE
specification is sought. Please refer to the attached table for the specifications.
