Product Description
HLK-RM58N is a low-cost embedded UART WIFI (Serial Wireless Network) module launched by Hi-link Electronics. This product is based on an embedded module that complies with network standards through a serial interface, embedded with the TCP/IP protocol stack, and capable of converting between user serial port and wireless network (WIFI).
Through the HLK-RM58N module, traditional serial devices can transmit their data over the Internet network without changing any configuration, providing a complete and fast solution for users' serial devices to transmit data over the network.
