Details
This is an industrial-grade integrated 802.11b/g/n module, which can realize TTL serial port, WiFi, and Ethernet port bi-directional transparent transmission. It combines multi functions in one, including serial server, Modbus gateway, MQTT gateway, UART to HTTPD Client, etc. Traditional serial port devices or MCU control devices can quickly access the WiFi wireless network by using this WiFi module. It is small in size, easy to install, and suitable for applications like data acquisition, IoT gateway, safety & security IoT, and intelligent instrument monitoring...

Support UART To WiFi, UART To Ethernet, Ethernet to WiFi, etc.
Support TCP Server, TCP Client, UDP Server, UDP Client
Devices can subscribe to other MQTT client messages, and can publish topic information to the server. Supports subscription of 6 messages and publication of 6 topics, wider range of use and more applicable scenarios. Users can view device-related information through terminal devices or cloud platforms.
After the user has set the HTTP header through AT commands or web page, the module can send data to the HTTP server, or obtain data from the HTTP server
Users send data to servers according to the protocol and can send data to different servers without restarting
Support Modbus TCP And Modbus RTU Interconversion Mode
Support AP mode, STA mode, and AP+STA mode
Multi Configuration Methods
Supports multi configuration methods such as hosts, Web Browser and serial port Configuration
Built-In webpage
Built-in webpage, and supports setting IP address, port number, serial port baud rate and other parameters through webpage.
AT Command Mode
The user can query the current status of the module or set related parameters by sending AT commands
Socket Distribution Protocol
In the transparent transmission mode, the serial device can send data to the specified Socket link; the network data of each Socket is sent to the serial device through the serial port
Support Websocket function
The Websocket function is to realize the data interaction between the module webpage and the module serial port; The Websocketserver function can make the serial port of the module interact with the webpage in real time, replacing the earlier HTTPGET, POST, and PUT methods for a faster response time.
Customized registration packets, heartbeat packets
The registration package is used to identify the device information to the server, so that the server can identify the device
100M Ethernet port
Through this Ethernet port, it is possible to transfer data between the WiFi, serial port and Ethernet port.
Weight: 0.011 kg
