HLK-RM04 is a low-cost embedded UART-ETH-WIFI module (serial port – Ethernet – Wireless network) developed by Shenzhen Hi-Link Electronic co., Ltd. The HLK-RM04 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 ethernet providing a quick solution for the user’s serial devices to transfer data via ethernet.
