Upgraded USR-TCP232-T2 Tiny TTL UART to Ethernet TCP/IP Serial Converter Module

This upgraded tiny USR-TCP232-T2 serial module is a compact TTL UART to Ethernet TCP/IP converter, designed to convert serial TTL data into standard Ethernet network signals for remote data communication. It supports DHCP auto IP acquisition and DNS domain access, greatly simplifying network setup without complicated static IP configuration. Multiple transmission modes including TCP Server, TCP Client and UDP transparent transmission are available to meet diverse IoT connection demands. With ultra-small form factor and low power design, the module delivers stable long-distance serial data transfer. It widely works with MCU, sensors, access control boards and other TTL serial equipment, ideal for smart home, industrial monitoring, remote data acquisition and small-scale IoT projects.

Users can easily set parameters via web page or serial AT commands, supporting remote firmware update to maintain stable long-term operation.
