HLK-RM04 is a new low-cost embedded UART-ETH-WIFI module that allows for seamless conversions between serial port, Ethernet, and wireless network (wifi). It features a built-in TCP/IP protocol stack for easy data transmission over the Internet network without the need for configuration changes on traditional serial devices.
With a working temperature range of -25~75°C, this module is equipped with a 360M MIPS CPU, 16M RAM, 4M FLASH, wireless baseband, RF front-end, and multi-peripheral bus. It supports IEEE 802.11 b/g/n, various encryption types, and offers an AT+ instruction set for easy configuration.
The HLK-RM04 supports AP and Station modes, allowing for simultaneous connections with iPhone and Android devices. It offers TCP server/TCP Client/UDP work modes and supports network protocols like TCP, UDP, ARP, ICMP, HTTP, DNS, and DHCP. Additionally, it supports DHCP auto IP assignment and serial speed ratio adjustment up to 320400.
