WIZ830MJ

WIZ830MJ

The WIZ830MJ is a high-performance Ethernet module based on the W5300 hardwired TCP/IP chip with integrated MAC and PHY.
It includes an onboard RJ45 (MAG-JACK) and necessary interface logic, allowing developers to rapidly add Ethernet functionality to embedded systems.
Designed for easy integration via a 16/8-bit parallel MCU BUS interface, WIZ830MJ offers outstanding throughput and stability for industrial applications.
