This product is an embedded module based on the universal serial interface and conforms to the network standard. It has a built-in TCP/IP protocol stack, which can realize any transparent conversion between three interfaces of user serial port, Ethernet, and wireless network (WIFI). With the HLK-RM04 module, traditional serial devices can transfer their data over the Internet without changing any configuration. Provides a quick solution for the user's serial device to transmit data over Ethernet
