HLK-M30 Data Sheet
HLK-M30-DS V1.0 7/30/2014
1. Introduction
The HLK-M30 module provides designers with a ready made component that provides a fully integrated solution for
applications, using the IEEE802.11 standard in the 2.4-2.5GHz ISM frequency band, including802.11b/g/n, can be quickly
and easily included in product designs. The modules integrate all of the RF components required, removing the need to
perform expensive RF design and test. Products can be designed by simply connecting sensors and switches to the
module IO pins or uart interface. The modules use MTK’s chip Wireless Microcontroller, allowing designers to make use of
the serial interface to connect with their device. Hence, this module allows designers to bring wireless applications to
market in the minimum time with significantly reduced development effort and cost.
The HLK-M30 is an embedded module based on the universal serial interface network standard,built-in TCP / IP
protocol stack, enabling the user serial port, wireless network (wifi) interface between the conversions. Through the
HLK-M30 module, the traditional serial devices do not need to change any configuration; data can be transmitted through
the Internet network. Provide a quick solution for the user’s serial devices to transfer data via Ethernet Also the HLK-M30
module have FCC modular approvals and is compliant with EU regulations.
