Quick Overview

2mm pin header Ethernet to Serial module with W7500


Product Description

The WIZ750SR-105 is a compact sized serial to Ethernet module using the W7500 Ethernet MCU (SoC based on ARM Cortex-M0 architecture) with an external PHY (IC+). WIZ750SR-105 is a protocol converter that transmits data sent by serial equipment as TCP/IP data and converts the TCP/IP data received through the network back into serial data to the serial equipment. It complies with industrial temperature standard. It is compatible with the WIZ105SR module and, In addition, contains a 4-pin GPIO expansion port that can be controlled freely by the user as analog inputs or digital in/outputs.

The WIZ750SR-105 is compatible with the AT command set from WIZ107SR/WIZ750SR as the firmware and the configuration tool is the same for the board family.
