USR-ES1 is an Ethernet module with SPI interface, with an interface level of 3.3V TTL level and a power supply voltage of+3.3V. Please ensure that the current is not less than 200mA, the voltage is continuously stable at+3.3V, and the pins are compatible with Wiznet’s official module WIZ820io.
USR-ES1 is embedded with Wiznet W5500 chip, which uses hardware logic gate circuits to implement the transport layer and network layer of TCP/IP protocol stack (such as: TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE and other protocols are integrated with data link layer, physical layer, and 32K bytes of on-chip RAM as data transmission and reception cache. Enable the main control chip of the upper computer to only handle the processing tasks of TCP/IP application layer control information. This greatly saves the workload of the upper computer in data replication, protocol processing, and interrupt handling, and improves system utilization and reliability.
During the operation, users can approximately use W5500 as a peripheral RAM for MCU. The external interface of W5500 is a universal 80MHz high-speed SPI, which can be used to expand high-speed Ethernet solutions on different platforms.

Special Reminder:
1. Communication is not possible: Please use a regulated 3.3V power supply to ensure that the current can be above 200mA for power supply.
Unable to communicate, unrecognized network cable connection: W5500 does not support Auto-MDI-X, which means it does not support automatic switching between cross and direct connections. For some older devices, specific cross or direct connections may be required. For example, connecting modules requires the use of cross wires, while connecting modules to routers or switches requires the use of straight wires.
