The Ethernet Shield is based on the Wiznet W5100 ethernet chip, which provides a network (IP) stack capable of both TCP and UDP. It allows an Arduino board to connect to the internet and supports up to four simultaneous socket connections. The shield also features an onboard micro-SD card slot for storing files to serve over the network.
Do not use the shield with the Mega without manually resetting it after power-up.
Do not attempt to use a full-size SD card with the shield as it is not supported.
Use the Ethernet library to write sketches that connect to the internet using the shield.
Ensure proper connection to the Arduino board using long wire-wrap headers.
Utilize the onboard micro-SD card slot for storing files for serving over the network.
Provides stable power output with minimal noise.
Protects the shield from damage due to excessive current or short circuits.
Connect the Ethernet Shield to an Arduino board using long wire-wrap headers.
Ensure the pin layout remains intact for stacking additional shields on top.
Access the onboard micro-SD card slot through the SD Library with SS on Pin 4.
