USR-K5 is a cost-effective TTL UART to Ethernet module with tiny size that can realize the bi-directional transmission between UART and Ethernet. USR-K5 is used for data transmission between TCP/UDP packets and the UART interface.

USR-K series Super network port is a series of serial port to Ethernet modules with different appearance and function positioning, which can quickly realize the data transmission between the serial port and the network port. It has the characteristics of small size, low power consumption, fast speed and strong stability. The TCP/IP protocol stack is integrated inside the module, which can easily complete the networking function of embedded devices, save manpower/material resources and cycles in the development process, so that products can be put into the market faster and enhance competitiveness. The series of products rely on the ten years of technology and application accumulation, reliable performance, comprehensive features, has been widely used in medical devices, building intelligence, large company network, camera monitoring, instrumentation and automation and other products and fields, by the market. According to the appearance of half bag, it is divided into three heavyweight products: USR-K5, USR-K6, and USR-K7. USR-K7 is located in the industrial grade, Cortex-M7 core, strong expansion; USR-K6 is located in Cortex-M0 core, Modbus gateway USR-K5 is located in Cortex-M0 core, domestic core, high cost performance;
