W5100S-io
Overview
W5100S-io is a compact size network module that includes a W5100S (TCP/IP hardwired chip and PHY embedded).It can be used as a component and no effort is required to interface W5100S. The W5100S-io an ideal option for users who want to develop their Internet enabling systems rapidly. W5100S-io is hardware compatible with W5500-io and W6100-io.
For the detailed information on implementation of Hardware TCP/IP, refer to the W5100S Datasheet.
