Ten small green circuit boards with RJ45 ports and pin headers

Vszerda

Vszerda USR-K7 TTL UART to Ethernet Module 10PCS

SKU CH-AKFQ-GH1JM

Pack of ten UART-to-Ethernet modules with ARM Cortex-M4 processor, 10/100 Mbps RJ45 port, Modbus RTU-to-TCP gateway and web-based configuration

  • Transparent network-to-serial data transmission via ARM Cortex-M4 processor
  • Virtual COM port enables legacy serial devices to communicate over Ethernet networks
  • Automatic dead-link detection and reconnection prevents data loss during outages
  • Modbus RTU-to-TCP gateway with polling mechanism resolves data congestion issues
  • Configurable once via software or web interface with settings saved permanently

Ten-pack UART-to-Ethernet modules

This pack supplies ten Vszerda USR-K7 modules that bridge TTL serial devices to a 10/100 Mbps Ethernet network. Each module uses an ARM Cortex-M4 processor to handle transparent data transmission and protocol conversion. Configuration is performed once through software or the built-in web page and then stored permanently.

Integration into a serial-to-network project

The modules present an RJ45 port for wired LAN connection and a TTL UART interface for the target device, enabling legacy equipment to reach servers over TCP/IP. Virtual COM support lets existing PC software communicate with networked hardware without code changes. Automatic reconnection and dead-link detection protect data flow during power interruptions.

Suitable for batch automation upgrades

Engineers converting multiple Modbus RTU devices to Modbus TCP will benefit from the ten-unit quantity and firmware 3009 or higher with polling-based congestion handling. Projects needing wireless connectivity, higher Ethernet speeds, or single-unit purchases should consider other options.
