The USR-TCP232-T2 is an upgraded, miniature TTL serial to Ethernet converter providing bidirectional transparent data transmission between a TTL port and an RJ45 Ethernet port. Based on a Cortex-M0 core, this low-power module supports 10/100Mbps Ethernet, TCP/UDP modes, and DHCP/DNS, making it ideal for industrial automation, IoT, and remote device management.

Key Features and Upgrades

Bidirectional Transmission: Seamlessly transfers data between Serial (TTL) and Ethernet.

Enhanced Performance: Features a 32-bit ARM Cortex-M0 core for faster, more efficient processing than its predecessor.

Tiny Form Factor: Compact design fits easily into space-constrained embedded systems.

Operating Modes: Supports TCP Server, TCP Client, UDP Client, UDP Server, and HTTPD Client.

Configuration: Easy configuration via built-in webpage, AT commands, or software.

Reliability: Includes a heartbeat packet mechanism to ensure connection stability and a user-defined registration package for security.

Network Features: Supports DHCP for automatic IP address acquisition and DNS for remote server access.

Industrial Ready: Wide operating temperature of

and 2KV electromagnetism isolation.
