2.0 mm pitch Serial to Ethernet module based on W7500 (TCP/IP, MAC, PHY, MCU)

Product Description

2.0 mm pitch compact size Serial to Ethernet module

Please note: This module has been released as WIZ750JR and has been renamed to WIZ750SR-100 in January 2018.

The WIZ750SR-100 ist the compact size Serial to Ethernet Module based on the W7500, which is based on the Cortex M0. The module has a pin pitch of 2.00 mm and is a full hardware replacement of WIZ100SR. Beside the W7500 the module contains an external Phy chip from IC+. The TTL level serial signals TXD, RXD, RTS, CTS, GND can be transmitted to the Ethernet port and vice versa. Beside the well known pins from the WIZ100SR this module contains 4 additional GPIO expansion ports which can be used as analog or digital ports.



  • Serial to Ethernet Module based on W7500 MCU (TTL level)
  • Includes External PHY chip
  • Software and Hardware compatible with WIZ100SR module
  • 10/100Mbps Ethernet & Up to 230kbps serial speed
  • 2.00 mm pin pitch pin headers
  • 4 configurable user pins (analog/digital I/O)
  • Status pins: PHY link status / TCP connection status
  • Serial signals (TTL): TXD, RXD, RTS, CTS
  • Optional DTR/DSR signals supported (Status pins or DTR/DSR pins selectable)
  • Data UART and Debug UART port
  • Enhanced module security with password protection for network search and configuration setup
  • Configuration is possible via serial AT commands or via Configuration tool
  • Built in Supervisor IC for improvements of Reset function stability
  • Compact size: 50 x 30 x 12 mm (Length x Width x Height)
