USR-TCP232-S2 is a tiny size SMT Ethernet module that can realize data bidirectional transparent transmission between TTL and Ethernet Port. It can also be applied in RS232/ RS485 by a level shift circuit. USR-TCP232-S2 is based on the Cortex-M0 core. It has characteristics of low power, fast speed, and high efficiency.
