RemoteXY Ethernet W5100 shield
Ethernet W5100 shield made in RemoteXY allows remote control of microcontrollers over Ethernet networks.
The shield is connected to the Arduino board and communicates with the W5100 chip via the SPI bus.
The RemoteXY Arduino Library includes header files for communicating with the W5100 chip, allowing you to set the IP address of the W5100 chip or configure it to obtain one via DHCP.
To connect to the module from a smartphone or tablet, you can input the module's IP address in the RemoteXY app to establish a connection.
