Description

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

HLK-RM04 UART-to-Ethernet/Wi-Fi module with 2.4–2.5 GHz Wi-Fi, dual 10/100 Ethernet ports and UART rates from 1200 to 500000 bps.

The Hi-Link HLK-RM04 is an embedded UART-to-Ethernet and Wi-Fi module that links serial devices to wired or wireless networks. Its built-in TCP/IP stack handles network communication, while its 2.4–2.5 GHz Wi-Fi and two 10/100 Ethernet ports support different connection setups.

The module supports transparent data transmission and AT commands, so engineers can choose how they control data flow. Serial or web configuration helps with setup, and support for common network protocols gives the module a role in varied network designs.

Use the HLK-RM04 in home and commercial building automation, telemetry, or remote control systems. It can also support OBDII Wi-Fi diagnosis and RFID data transfer where devices need to send serial data over a network.
