WIZ810MJ

WIZ810MJ

The WIZ810MJ is a plug-in Ethernet module featuring the W5100 hardwired TCP/IP chip with integrated PHY and RJ45 (MAG-JACK).
It allows developers to add Ethernet connectivity to embedded systems without complex hardware design.
Ideal for quick prototyping and reliable network-enabled product development.
