Description:HLK-RM04 is a new low-cost embedded UART-ETH-WIFI module (serial port - Ethernet - Wireless network) developed by Shenzhen Hi-Link Electronic co., Ltd. This product is an embedded module based on the universal serial interface network standard, built-in TCP / IP protocol stack, enabling the user serial port, Ethernet, wireless network (wifi) interface between the conversions. Through the HLK-RM04 module, the traditional serial devices do not need to change any configuration; data can be transmitted through the Internet network and it provides a quick solution for the user’s serial devices to transfer data via Ethernet.Products can be designed by simply connecting sensors and switches to the module IO pins ao UART inteface. Module use ralink chip wireless microcontroller, allowing designers to make serial interface to connect with their device. Hencce, the module allows designers to bring wireless application to the market in minimum of time.
