Ethernet W5500 Wiznet Network Module

The W5500 Ethernet Module from Wiznet provides a high-performance network interface for your microcontroller projects. With hardwired TCP/IP support for protocols such as TCP, UDP, ICMP, IPv4, ARP, IGMP, and PPPoE, it allows fast and reliable network connectivity. The module supports 8 independent sockets simultaneously, high-speed SPI communication, and includes 32KB internal memory for TX/RX buffers.

This module operates at 3.3V and tolerates 5V I/O signals, making it compatible with a wide range of microcontrollers. LED indicators show full/half duplex, link status, speed, and network activity. With 10BaseT/100BaseTX Ethernet PHY embedded and auto-negotiation support, the W5500 is ideal for IoT, Ethernet-enabled sensor projects, and embedded networking applications.
