HLK-RM04 is a new embedded UART-ETH-WIFI module (serial port - Ethernet -Wireless network). 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. Provide a quick solution for the user’s serial devices to transfer data via Ethernet. -

The board has in built Programmer capable of programming both AVR & 8051 family ICs.A 40 pin ZIF socket is used as Target to hold the 8051 IC. Additional 40 pin ZIF socket with modified connection is provided to host AVR ICs.This additional ZIF socket should be placed over the on- board ZIF socket to use AVR ICs.
