W5500 Network Module
Description
The W5500 chip is a Hardwired TCP/IP embedded Ethernet controller that provides easier Internet connection to embedded systems.
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.
SPI to Ethernet Hardware TCP/IP W5500 Ethernet Network Module has 8 independent ports run at the same time, Module supports 3.3V or 5V power supply, convenient for the user to use in the SCM system different, module and MCU system communication mode is SPI protocol. Support SPI clock frequencies up to 80M, provide STM32 and 51 SCM client, server, three modes of UDP routines.

Library
A wide selection of libraries exists, but the standard one Is the best choice.
You can find It in the standard Arduino library manager.

SSLClient
This library and device do not support SSL, so to add these features exists an alternate library named SSLClient that needs a little patch of Ethernet.
SSLClient adds TLS 1.2 functionality to any network library implementing the Arduino Client interface, including the Arduino EthernetClient and WiFiClient classes. SSLClient was created to integrate TLS seamlessly with the Arduino infrastructure using BearSSL as an underlying TLS engine. Unlike ArduinoBearSSL, SSLClient is entirely self-contained and does not require any additional hardware (other than a network connection).
