MT7628K chipset wireless router module TTL Serial to Wifi Module Test Board HLK-RM28K
HLK-RM28K is a cost-effective embedded serial port-network (TCP/UDP) transparent transmission module launched by Hi-link Electronics. The network adopts 100M Ethernet
Ethernet port and 2.4G WiFi. The network transport layer supports TCP client/server, UDP client/server, and can automatically send network login packets (TCP
Client mode) and serial heartbeat packets.
Built-in TCP/IP protocol stack, support routing function, WAN port can be connected to the upper router to connect to the external network, LAN port can be connected to the computer
or other devices that can be used as wireless routers. Wired or wireless bridging is also supported.
By using this module, traditional serial devices can transmit their own data on the Internet network without configuration or minimal configuration.
A variety of networking methods and network transmission protocols can be freely configured through serial port AT commands or web pages to transmit data through the network for the user's serial device.
It provides a complete and fast solution.
Support two serial ports - network transparent transmission at the same time, each channel can be configured and worked independently
Reliable and stable network transmission, support automatic reconnection, keepalive, etc.
Network transmission supports TCP client/server, UDP client/server, and supports access through domain names
The parameters of the module can be configured through serial AT commands and WEB pages
Supports sending network AT commands via UDP
Built-in WDG watchdog function, effectively prevent the abnormal software crash
And there is a WDG signal output that can be used externally to detect whether the module is working normally
Serial port baud rate up to 2Mbps
Up to 5 Ethernet ports, 1 WAN port, 4 LAN ports
2.4G WiFi, wireless standard supports IEEE 802.11 b/g/n, supports STA, AP and AP Client
Built-in TCP/IP protocol stack, support DHCP, DNS and other rich functions
Support serial port 0 heartbeat packet and network login packet function in TCP Client mode, the content of heartbeat packet and login packet can be customized
