W5500 Ethernet TCP/IP Protocol Stack SPI IOT Compatible WIZ820io Shield

USR-ES1 is embedded with Wiznet’s W5500 chip, and uses hardware logic gate circuits to implement the transport layer and network layer of the TCP/IP protocol stack (such as: TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE and other protocols), and integrates The data link layer, physical layer, and 32K bytes of on-chip RAM are used as data receiving and sending buffers. Make the host computer main control chip, only need to undertake the processing task of TCP/IP application layer control information. This greatly saves the workload of the host computer for data replication, protocol processing, and interrupt processing, and improves system utilization and reliability.
