Ethernet network module based on WIZnet W5500

WIZnet‘s Hardwired TCP/IP is the market-proven technology that supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE protocols. W5500 embeds the 32Kbyte internal memory buffer for the Ethernet packet processing. If you use W5500, you can implement the Ethernet application just by adding the simple socket program. It’s faster and easier way rather than using any other Embedded Ethernet solution. Users can use 8 independent hardware sockets simultaneously.

Official support in Arduino Core (that means more tested and up to date library). Modules on Wiznet chipsets are slightly more expensive than modules on ENC28J60. Wiznet chipset, unlike ENC, process protocol stack and operations in hardware, which means less work for main microcontroller. This is quick and convenient solution even for 8-bit systems like Arduino. In addition, Wiznet chips allow you to use theirs RAM, which is another bonus. The last, but equally important argument to use Wiznet has the official support of Arduino, thanks to a much better developed library we can learn to program this module faster. And of course final program will also be smaller.
