Introduction

The Super Network Port USR-K7 is a brand-new, compact serial-to-Ethernet module that enables transparent data transmission between an Ethernet port and a TTL serial port. This module is powered by an ARM Cortex-M4 processor, offering the advantages of low power consumption, high speed, and excellent stability. In terms of size, the module's width is equivalent to that of a standard RJ45 connector, with a length less than twice that of a typical network port connector — representing an industry-leading ultra-compact form factor. The current draw is only 130mA during full-speed operation. With an integrated TCP/IP stack, users can easily implement network connectivity for embedded devices, reducing the manpower, resources, and development time required during the development process, enabling products to reach market faster and enhancing competitiveness. This product has undergone rigorous testing and has been successfully deployed in complex network environments, including banking networks, highway networks, large enterprise networks, high-traffic camera networks, and fiber-to-Ethernet conversion scenarios.
