WIZ610MJ
WIZ610MJ

The WIZ610MJ is a compact Ethernet module that integrates the W6100 hardwired TCP/IP chip with an embedded PHY and an RJ45 MAG-JACK. It supports both IPv4 and IPv6 Dual Stack, enabling flexible networking for modern embedded systems. By combining all essential Ethernet hardware in one module, it eliminates complex PCB design for the transformer and RJ45 interface. The WIZ610MJ is ideal for developers who want to implement network-enabled systems quickly and reliably.
