UART to Ethernet Module

The TTL UART to Ethernet module from Waveshare is a compact module that enables a bidirectional transparent data transmission between serial interface and Ethernet. It features gold-plated soldering eyes for easy integration into various product applications. It supports multiple communication modes such as TCP server, TCP client, UDP multicast and UDP mode. It can also be used as a Modbus gateway or MQTT gateway. It supports NTP protocol, web and host computer configuration. It has low power consumption and high stability.

Features:

Supports TCP server, TCP client, UDP mode and UDP multicast. As a TCP client, it also supports TCP server functions. Supports 30 TCP connections as a TCP server and 7 target IPs as a TCP client.
Supports the function of sending the MAC address when the device is connected, which is convenient for cloud management of devices.
Provides a secondary development kit DLL development library for computer-side search and configuration of devices.
Supports web browser configuration, supports dynamic DHCP capture of IP and DNS protocol connection name server addresses.
Supports remote search for devices, configuration of device parameters and updating of device demos in the cloud.
Supports remote viewing of the TCP connection status, sending data via the serial interface and receiving the device status via the software. The virtual serial interface supports the data monitoring function.
