The HLK-M30 module is officially released: This module is different from other manufacturers' original products. We have already completed the complete system and can directly test it.

Not only low prices, stability is reliable, the service can win.

Universal development test suite

Hailingke Electronics offers two evaluation development kits, HLK-M30, for customers to quickly familiarize themselves with products and deep application development. Users can use the RS-232 serial port debugging module of the computer to perform parameter configuration, module management and function testing.

The HLK-M30 is a new low-cost embedded UART-WIFI (serial-wireless network) module from Hailingke Electronics.

This product is an embedded module based on the universal serial interface and conforms to the network standard. It has built-in TCP/IP protocol stack, which can realize the conversion between user serial port and wireless network (WIFI).

With the HLK-M30 module, traditional serial devices can transfer their data over the Internet without changing any configuration. Provides a complete and fast solution for users' serial devices to transmit data over the network.
