Breadboard friendly upgrade from official Arduino shield.
- W5500 chip.
- Size 2.5 x 5 cm.
- Require 3.3V.
- Up to 80Mhz SPI.
- RJ45 jacks with integrated magnetics.
- ACT and LINK LEDs.
- Standard 0.1″ pin header with GND, 3V3, SS, SCK, MISO, MOSI, RST, INT pins.
I have made this board to test W5500 chip as upgrade from W5200 for my gateway board Alarm / Automation. And it is working for me in other test cases as well. It is same design as original WizNet W550io, but does not have MAC address preprogrammed. Works with standard Arduino WizNet library.
The W5500 chip is a Hardwired TCP/IP embedded Ethernet controller that enables easier internet connection for embedded systems using SPI. 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.
