IoT smart serial port to WiFi wireless routing module RM08S development board MT7688KN chip solution


HLK-RM08S is an embedded WiFi module conforming to network standards based on a universal serial interface, with a built-in TCP/IP protocol stack, which can realize the mutual conversion between serial port, Ethernet, and wireless network (WIFI) interfaces.
Can quickly solve the user's serial device network transmission data problem, the traditional serial device does not need to change the configuration directly to the network.
