USR-K2 Low Cost Serial TTL UART to Ethernet TCP/IP Module Support 10/100M Auto Detect Interface

Introduction

This is a serial TTL to Ethernet module, used for data transparent transmission. USR-K2 is the low-cost and multifunctional version of Super Port. It is an embedded serial networking module, whose function is to realize bidirectional transparent transmission between TTL and Ethernet.

The amazing part of K2 lies in its Ethernet port integration design. You can apply K2 to your products to realize networking communication. User can directly process data interaction through network and device to realize remote data acquisition, remote control and management.

K2 is based on M0 solution,which has slightly higher price and a bit more functions.
