2PCS SPI to LAN Ethernet Module Featuring W5500 Chip ES1 DY

-ES1 is an Ethernet module with SPI interface, the interface level is 3.3V TTL level, the power supply voltage is +3.3V, please that the current is not less than 200mA, the voltage is continuously stable +3.3V, and the pins are compatible Wiznet's official module WIZ820io. -ES1 embeds Wiznet's W5500 chip, uses hardware logic gates to implement the transport layer and network layer of the IP protocol stack (such as: , UDP, ICMP, IPv4, , IGMP, PPPoE and other protocols), and integrates 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 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. During operation, users can use W5500 as a peripheral RAM of MCU approximately. The external interface of W5500 is a universal 80MHz high-speed SPI, which is available for different platforms to expand high-speed Ethernet solutions. size:26x24x17mm Material:PCB colour:As Shown Package Contents: 2 x Module Only the above package content, other products are not included.
