The Arduino Ethernet Shield Clone is an Ethernet Controller Board with W5500 Ethernet Controller which allows us to connect to internet through ICSP (In-Circuit Serial Programming). This Ethernet Shield Clone Module communicates with Arduino Mega Board through SPI connection with ICSP pins. Its operating power supply is 5V which is supplied from Arduino Mega 2560. It also has an Onboard SD Card slot which helps in Read/Write operation.

The Arduino Ethernet Module is a compact Ethernet Module with the ENC28J60 Ethernet controller chip, LAN connector and SPI interface for the microcontroller, arduino, avr, pic and so on. This Arduino Ethernet Module helps us to connect our projects to the network and the internet and run a web server or web client.

Ethernet is used to connect devices in a network and is still a popular form of network connection. For local networks used by specific organizations such as company offices, school campuses and hospitals. Ethernet is used for its high speed, security and reliability.

WT32-ETH01 is an embedded serial to Ethernet module based on the ESP32 series WT32-S1 MCU. The module integrates an optimized TCP/IP protocol stack, which is convenient for users to easily complete the networking functions of embedded devices while reducing development time cost. In addition, the module is compatible with half-pad and through-hole connectors. The board width is a universal width and therefore, it can be directly soldered to boards, connectors, or even breadboards, which is convenient for users to use in different scenarios.
