USR-K5 is a low-cost TTL UART to Ethernet module with tiny size, which can realize the bi-directional transmission between UART and Ethernet. USR-K6 is a new and tiny super port UART TTL to Ethernet module, which can realize the bi-directional transparent transmission between UART and Ethernet. USR-K7 is a super port TTL UART to Ethernet module. People may confused about what's the difference between Embedded serial to ethernet USR-K5, USR-K6 and USR-K7?
