1. Introduction

The JZ-WF-09 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 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-M35 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-M35 module have FCC modular approvals and is compliant with EU regulations.
