Quick Overview

The WIZ550S2E-TTL module includes Serial-to-Ethernet functionality. Hardwired TCP/IP W5500 included, TTL logic level input/output pins


Product Description

The WIZ550S2E-TTL is a gateway module that provides a RS-232 to TCP/IP converter This module enables remote management of a device through the network based on Ethernet and TCP/IP by connecting to an existing equipment with RS-232 serial interface. It includes the W5500 chip, which is providing hardwired TCP/IP Ethernet functionality. Furthermore, a Cortex M0 microcontroller is also included on this module. The module has TTL level logic inputs and outputs and can be combined with Interface Boards (WIZ550S2E-232-IBWIZ550S2E-485-IB) to provide RS232 or RS244/485 functionality.


  • Serial to Ethernet module based on W5500 & Cortex ARM M0
  • Module with pin headers with a pitch of 2.54mm (bread-board compatible)
  • configurable via AT commands & configuration tool
  • supports data communication using AT command : able to send data without re-configuring and re-boot of the module when changing the destination IP
  • interface boards for RS-232 and RS422/485 available
  • Dimension (mm) : 55(L) x 30 (W) x 23.49 (H)
