Features: USRK5 is a cost-effective TTL UART to Ethernet module with tiny size that can realize the bidirectional transmission between UART and Ethernet. USRK5 is used for data transmission between UDP packets and the UART interfaces. Users can use it easily to complete the networking function of material resources, and development cycle in the development process so that the product can be put into the market faster, enhances competitiveness. The Ethernet module USRK5 is the same as RJ45, USRK5 have been rigorously tested and have been successfully apply in Bank, large corporate networking, and complex Networking environment such as fiber-to-Ethernet. The USRK5 is featuring strong antiinterference capabilities and low power consumption, ensuring reliable performances in demanding environment.
