1. Introduction

MM511250-11 Wireless WIFI module is a low-power WIFI module for

the Internet of Things. It supports IEEE802.11b / g / n protocol. It also

embeds IPV4 / IPV6 TCP / IP, HTTP, DNS, FTP and other complete network

protocols, making the terminal more reliable, convenient and easy to

use.

The MM511250-11 module contains RTL8711AM single-chip solution.

the chip in software and hardware are used in low-power technology,

the purpose is to lower the power consumption of the entire board, the

product more competitive. At present, the module provides a

complete serial interface functions and equipment to communicate, so

you can through the serial port and mobile client to connect the cloud

and equipment.

As shown in Figure 1,the MM511250-11 module contains

RTL8711AM single-chip solution. The module uses the internal antenna

design in PCB, both for customers to reduce the cost of the antenna,

but also eliminates the need to consider the antenna assembly space.
