description requires an arduino board (not included) operating voltage 5v (supplied from the arduino board) ethernet controller: w5500 with internal 32k buffer connection speed: 10/100mb connection with arduino on spi port the arduino eternet shield 2 (w/poe) allows an arduino board to connect to the internet. It is based on the wiznet w5500 ethernet chip. The wiznet w5500 provides a network (ip) stack capable of both tcp and udp. It supports up to eight simultaneous socket connections. Use the ethernet library to write sketches that connect to the internet using the shield. The ethernet shield 2 connects to an arduino board using long wire-wrap headers extending through the shield. This keeps the pin layout intact and allows another shield to be stacked on top of it.
