compact size Ethernet to TTL converter based on W7500p. Fully compatible with WIZ107SR/WIZ108SR.

Product Description

The WIZ750SR is the compact sized serial to Ethernet module using the WIZnet chip W7500P, based on a Cortex M0. The WIZ750SR 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. The WIZ750SR is the successor of the widely used WIZ107SR/WIZ108SR and incorporates the experience of several years of module development. It complies with industrial temperature standard and supports all relevant serial interface systems (TTL / RS-232 / RS-422/485). WIZ750SR contains an 4-pin GPIO expansion port that can be controlled freely by the user. (analog input or digital in/out)

This module is the TTL version and supports the 3.3 V TTL logic.
