SMT Serial Ethernet Module-USR-TCP232-S2

Serial Ethernet data transmission System Information

USR-TCP232-S2 is a tiny SMT serial TTL UART to Ethernet module which can realize data bidirectional transparent transmission between TTL and Ethernet port. It can also be applied in rs232/ rs485 by level shift circuit. USR-TCP232-S2 is based on Cortex-M0 core. It has characters of low power, fast speed and high efficiency.
