HLK-RM04 RM04 Uart Serial Port to Ethernet WiFi Wireless Module with Adapter Board Development Kit

1. Brief Introduction

1). This product is an embedded module based on the universal serial interface network standard, built-in TCP / IP protocol stack, enabling the user serial port, Ethernet, wireless network (wifi) interface between the conversions.

2). Through the HLK-RM04 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 users serial devices to transfer data via Ethernet.

HLK-RM04 Mechanical Dimensions(mm) is shown in the following picture:

5. Features:Full function of wireless router:

 

1). Support 5 types of work mode: AP, Client, Repeater, Bridge, Router

2). AP mode- Default work mode. In this mode, the device works as a wireless access point, support for plug-and-play, and no configuration needed.

3). Router mode-In this mode, the device is equivalent to a wireless router, wired interfaces can be used as WAN, wireless used as LAN. Multiple wireless clients can share a broadband line to search the Internet.

4). Repeater mode -Use the radio relay function of the device, achieve the radio signal repeat and amplified, and form a new radio coverage area, ultimately attain the purpose of extending the coverage of the wireless network.

5). Bridge mode-With the Bridging function of equipment, firstly, the module RM04 establish a wireless connection with the front-end wireless network itself ,then sending the wireless signal, at the same time, form a new wireless coverage, signal weak and signal blind spot can be solved effectively.

5). Client mode -The AP to work in this mode for the main AP is a wireless client, the equivalent of a wireless network card.
