## Components

- **WIZnet W5500** x 1 ([docs](https://docs.wiznet.io/Product/Chip/Ethernet/W5500))

WIZnet parts: W5500 ([Datasheet](https://docs.wiznet.io/Product/Chip/Ethernet/W5500/datasheet?utm_source=maker&utm_medium=project&utm_campaign=w5500), [product hub](https://maker.wiznet.io/products/w5500/))

## Article

Usr-es1 embedded Wiznet W5500 chip, the use of hardware logic gate circuit to achieve the TCP/IP protocol stack of the transmission layer and network layer (such as: TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE and other protocols), and the integration of the data link layer, the physical layer, and 32K byte chip RAM as the data transceiver cache.So that the host computer chip, only to undertake the TCP/IP application layer control information processing task.Thus greatly saves the upper computer for data replication, protocol processing and interrupt processing and other aspects of the workload, improve the system utilization and reliability.
