HLK-M30 Description

Short technical summary and product information.

The HI-LINK HLK-M30 is a compact and low-power embedded UART-to-WiFi module designed for seamless integration into existing serial devices. It features a built-in TCP/IP protocol stack, allowing serial data to be converted for transmission over wireless networks.

This module supports the 802.11 b/g/n protocols and all common WiFi encryption methods. It operates in both AP (hotspot) and STA (WiFi node) modes, offering flexibility for various network configurations. The HLK-M30 also supports TCP Server/Client and UDP Server/Client functionalities, along with advanced protocols like DHCP, DNS, and HTTP.

Designed for ease of use, the HLK-M30 requires no user drivers and can be treated as a standard serial port by the host microcontroller. Configuration is managed via UART AT commands. Its ultra-small size (14.1x16.5x2.25mm) and low power consumption make it suitable for space-constrained applications. The module boasts a fast startup time of 1 second and includes SmartLink intelligent networking for easy setup via a mobile app.

This module is supplied in an SMD package for surface mounting.
