WIZ550S2Elink

WIZ550S2E is a gateway module that converts serial protocol (RS-232/422/485) into TCP/IP protocol. This module enables remote gauging, remote management of the device through the network based on the Ethernet and the TCP/IP by connecting to existing equipment with serial interface. In other words, WIZ550S2E is a protocol converter that transmits the data sent by serial equipment as TCP/IP data type or vice versa.

WIZ850iolink

WIZ850io is a compact size network module that includes a W5500 (TCP/IP hardwired chip and PHY embedded), a transformer and RJ45. It can be used as a component and no effort is required to interface W5500 and Transformer. The WIZ850io is an ideal option for users who want to develop their Internet enabling systems rapidly. WIZ850io is hardware compatible with WIZ820io. WIZ820io users, to migrate to WIZ850io, need to modify the Firmware.

W5500-EVB-Picolink

W5500-EVB-Pico is a microcontroller evaluation board based on the Raspberry Pi RP2040 and fully hardwired TCP/IP controller W5500 – and basically works the same as Raspberry Pi Pico board but with additional Ethernet via W5500.
