This is HLK-RM04 UART to Serial Wifi Ethernet Wifi Module. HLK-RM04 was designed based on a low-cost UART-ETH-WIFI module (serial port – Ethernet -Wireless network). Thus this embedded module is designed based on the universal serial interface network standard, with a built-in TCP / IP protocol stack. As a result, enabling the user serial port, Ethernet, wireless network (wifi) interface between the on versions. This module provides a quick and ideal solution for the user’s serial devices to transfer data via Ethernet. HLK-RM04 through the module, there is no need for any traditional serial devices to change any configuration. Hence the data can be transmitted through the Internet network.
The HLK-RM04 module designed with a completely developed component provides a fully integrated solution for applications. It supports the IEEE802.11 standard in the 2.4-2.5GHz ISM frequency band, including802.11b/g/n. And also supports IEEE802.3 designs. Meanwhile, the modules integrate all of the RF components required, eliminating the need to perform expensive RF design and test. Therefore, Simply connecting sensors and switches to the module IO pins or UART interface can design products. Moreover, the modules make use of Ralink’s chip Wireless Microcontroller, allowing designers to make use of the serial interface to connect with their device.
Hence, this module allows designers to use a wide range of applications in minimum time with significantly reduced development effort and cost.
Applications:
- WiFi Led Control
- WiFi Power Switch
- Home and Commercial building automation
- OBDII WiFi Diagnose
- RFID Data Transfer
- Toys and gaming peripherals
- Industrial systems
