Serial UART To Ethernet Module, Brand Name : USR

Introduction
USR-TCP232-T2 is a tiny size serial Ethernet module which can realize data bidirectional transparent transmission between TTL and RJ45 Port. It can also be applied in RS232/ RS485 by level shift circuit.USR-TCP232-T2 is based on Cortex-M0 core. It has characters of low power, fast speed and high efficiency.
