WIZ145SR

Overview

WIZ145SR is an embedded module based on WIZnet W5300 & ARM Cortex-M3. WIZ145SR is the protocol converter that transmits the data sent by serial equipment as TCP/IP data type, and converts back the TCP/IP data received through the network into serial data to transmit back to the equipment.

Features

• Serial to Ethernet Module based on W5300 & Cortex-M3
• Pin-header & RJ-45 mounted module
