RS-232/UART - LAN/WiFi converter kit HLK-RM04

Product detailed description

The Hi-Link industrial communication module with the MT7688K chipset represents a powerful solution for IoT applications, network gateways and embedded systems. The module combines WiFi connectivity, Ethernet (1× WAN + 4× LAN) and serial interfaces, enabling easy integration of devices into both local and remote networks. With support for AP, client, router and transparent data transmission modes (UART ↔ Ethernet/WiFi), it is suitable for industrial control, smart homes or remote device monitoring.

To connect the module to Windows, software is required to create a virtual serial port. The module works with various programs, e.g. Virtual COMM Port Driver from NetBurner, HW VSP3 from HW-group, or Virtual Serial Port Driver from Eltima Software.
