UART To WIFI / Ethernet Module (HLK-RM04)

The  Wi-FI HLK-RM04 module allows you to transform a  UART/USART port more commonly known as a serial in an attested port on an Ethernet network andor WI-FI, therefore, with the appropriate configurations and network structures allows any microprocessor, or anything else that can communicate on port UART / USART to reach and be reached from any point on the earth.
