RS232/485 to Ethernet converter (EU) - Waveshare 16530

Description

A converter that provides easy communication between the RS232 or RS485 interface and RJ45 Ethernet. The module is based on a 32-bit microcontroller with the ARM-Cortex M4 core. The device can work as a TCP server, TCP client, UDP server, UDP client or HTTPD client (supports GET and POST) and is configured using a website or AT commands. The converter has built-in reverse polarity protection and ESD protection. Full documentation is available on the product Wiki page.
