โมดูลแปลง SPI เป็น LAN USR-ES1 W5500 Chip SPI to LAN Ethernet Converter Module TCP / IP WIZ820io for arduino

      USR-ES1 embedded Wiznet's W5500 chip, using hardware logic gates 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 integrated The data link layer, physical layer, and 32K bytes of on-chip RAM are used as data transmission and reception buffers. So that the host computer's main control chip only needs to undertake the task of processing control information of the TCP/IP application layer. Therefore, the workload of the host computer for data replication, protocol processing and interrupt processing is greatly saved, and the system utilization rate and reliability are improved.

 

      During operation, the user can use the W5500 as a peripheral RAM of the MCU, which is very simple. The external interface of the W5500 is a general-purpose 80MHz high-speed SPI, which is used by different platforms to expand high-speed Ethernet solutions. Auto-negotiation LED status shows fast and stable SPI interface.

 

      Dimensions and pins are compatible with Wiznet official module WIZ820io

 

      Note: This module is not an SPI-to-Ethernet transparent transmission module. It needs to be used by an external single-chip microcomputer. Users need to know how to use the W5500 chip. Provide example code for STM32.
