The W5500 Ethernet Shield for Arduino from Seeed Studio is a great way to set up your projects with internet connectivity with just a single chip. Similar to the Arduino Ethernet Shield, but with a newer chipset, this ethernet shield supports both TCP and IP Protocols in TCP, UDP, ICMP, IPv4, ARP, IGMP, and PPoE format. The RJ45 ethernet port is also low enough so you can stack another shield on top of it
RS485, RS232 Interface Comfortable with W5100, W5200, W5500 Module Support STM32 program
The W5500 Ethernet module can be used to provide your projects with internet connectivity. W5500 enables users to have the Internet connectivity in their applications just by using the single chip in which TCP/IP stack, 10 / 100 Ethernet MAC and PHY embedded. Supports 8 independent sockets simultaneously. The W5500 Ethernet module has a standard RJ-45 connection. Support 3.3V and 5V input voltage and logic level from SPI. Work with All AVR(Arduino) STM, ARM boards.
Arduino Ethernet Shield W5100 is one of the most interesting expansion boards allows to control the Arduino board via LAN or Internet. This can be useful, if you need to get some information from a network, place your own web server. Or use Arduino for control a network. On this Ethernet Shield
This W5500 is a Ethernet module that basic on the new type chip W5500, The W5500 chip is a Hardwired TCP/IP embedded Ethernet controller that enables easier internet connection for embedded systems using SPI (Serial Peripheral Interface). W5500 suits users in need of stable internet connectivity best, using a single chip to implement TCP/IP Stack, 10/100 Ethernet MAC and PHY. Hardwired TCP/IP stack supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE, …, which has been proven through various applications over many years. W5500 uses a 32Kbytes internal buffer as its data communication memory. By using W5500, users can implement the Ethernet application they need by using a simple socket program instead of handling a complex Ethernet Controller. It is possible to use 8 independent hardware sockets simultaneously. SPI (Serial Peripheral Interface) is provided for easy integration with the external MCU. The W5500 SPI supports 80 MHz speed and the new efficient SPI protocol, so users can implement high speed network communication. In order to reduce power consumption of the system, W5500 provides WOL (Wake on LAN) and a power down mode.
