Quick Overview

WIZ850io is an compact size network module that includes a W5500 (TCP/IP hardwired chip and PHY embedded), a transformer and RJ45


WIZ850io is an compact size network module that includes a W5500 (TCP/IP hardwired chip with embedded PHY) a transformer and RJ45. The module is designed to be a fully pin-compatible replacement of the WIZ820io which has been widely used in the market over the last few years.The WIZ850io has a very small form factor just a little bigger than a usual RJ45 connector. The connection from the WIZ850io to your microcontroller is done by SPI mode 3. Already existing projects with the WIZ820io can be transformed to be used with the WIZ850io by modifing the firmware.
