1 Brief Introduction
HLK-RM04 is a new low-cost embedded UART-ETH-WIFI module (serial port - Ethernet -
Wireless network) developed by Shenzhen Hi-Link Electronic co., Ltd
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.
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 user’s serial devices to transfer data via Ethernet.
