Introduction

This product includes a RM04 module,a testing board, a power resource and a wire. The double serial ports, double network ports and Wi-Fi of this product makes it powerful and simple. It supports smart phone, web page, serial ports software, AT command and WPS encryption. The product also supports AP/STA mode with a choice between board-load and outlined wires. We have been providing this product steadily for four years and have an inventory larger than 5000 pieces. We shall be the first choice for the larger factories.


The HLK-RM04 is a flush type UART-ETH-WIFI module. It has a built-m RCP/IP negotiation wire and is able totransfer between serial port, Ethernet and Wi-Fi smoothly. With the HLK-RM04 module, the traditional serial port devices may upload its data through the Internet without any further changes.

Feature

  • TLL Serial port speed: 500KBPS Maximum

  • Wi-Fi: 802.1b/g/n

  • Size: 40*29mm

  • Working temperature: -25~75°C.

  • 360M MIPS CPU, 16M RAM, 4M FLASHand all kinds of peripheral circuits are built-in.

  • It is certified by CE and FCC,supports IEEE 802.11 b/g/n and the transparent data transporting mode. 

  • Supports the common WIFI encrypt ways which includes WEP/WAP-PSK/WAP2-PSK/WAPI.

 

This product supports five different working modes.

  • AP mode: The default working mode. The device works as a Wi-Fi access point and can be used when plugged in.

  • Router mode: The device works as a router. The wired port works as the WAN and the wireless port worksas a LAN. Multiple wireless clients may share the same broad board network.

  • Repeater mode: Uses the wireless relay function of the device to achieve the relay and enlargement of the signal and eventually form a new Wi-Fi covered area.

  • Bridge mode: Uses the bridge function of the device. First set a wireless connection between the RM04 and the front end wireless Internet, then release the signal from itself and form a new Wi-Fi cover zone.

  • Client mode: The AP works in this mode are wireless clients for the main AP.
