– The chip of HLK-RM08K is MT7688K , which can replace HLK-RM04. There are 4 net exports, 2 seriel ports and the power consumption is about 100mA.
– HLK-RM08K is a embedded module of UART-ETH-WIFI (serial-Ethernet-wireless network), which is based on MT7688K, a smart home networking WIFI module.
– This product is a embedded module that based the common serial interface that meets the network standard , built-in TCP/IP protocol stack, the user can achieve serial port, Ethernet, wireless network (WIFI) conversion between the 3 interfaces.
– Through the module, the traditional serial device, in the case of no change to any configuration, you can transfer your data through the Internet network.
