Description

Hi-Link HLK-RM04 UART-to-Ethernet and Wi-Fi Module

HLK-RM04 UART-to-Ethernet and Wi-Fi module with 2.4 GHz 802.11b/g/n, a built-in TCP/IP stack and UART rates from 1200 to 500000 bps.

The Hi-Link HLK-RM04 is an UART-to-Ethernet and Wi-Fi module that links serial equipment to wired or wireless networks. It has a built-in TCP/IP stack and supports 2.4 GHz Wi-Fi for network data communication.

Its client, access point and router modes let designers choose how the module joins a network. Transparent transmission provides a direct path for serial data, while UART, WAN and LAN interfaces bring device links together. The I-PEX RF port allows an antenna connection.

Use the HLK-RM04 in home and commercial building automation, telemetry and remote control systems. Its combined serial, Ethernet and Wi-Fi functions can connect equipment that needs to send data over a network.
