## Description

The W5200 Ethernet Shield adds wired internet connectivity to your Arduino. Simply stack it onto your board, connect an RJ45 cable, and start communicating over the network. The W5200 controller provides a 32 KB internal buffer — double that of the W5100 — and supports up to eight simultaneous TCP/UDP connections. An on-board microSD card slot allows file storage for serving data over the network. The lowered RJ45 jack and long wire-wrap headers ensure compatibility with additional shields stacked on top. The shield connects to Arduino via SPI.
