The Arduino Ethernet Shield 2 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.
There is an onboard micro-SD card slot, which can be used to store files for serving over the network. It is compatible with the Arduino Uno and Mega (using the Ethernet library). The onboard micro-SD card reader is accessible through the SD Library. When working with this library, SS is on Pin 4. The original revision of the Shield contained a full-size SD card slot; this is not supported.
The shield also includes a reset controller, to ensure that the W5500 Ethernet module is properly reset on power-up. Previous revisions of the Shield were not compatible with the Mega and needed to be manually reset after power-up. The most recent revision of the board exposes the 1.0 pinout on rev 3 of the Arduino UNO Board. The Ethernet Shield 2 has a standard RJ-45 connection, with an integrated line transformer and Power over Ethernet enabled but please be aware that this shield does not come with a built in PoE module. The PoE module that you will need is a separate component that must be added on. This shield also features several TinkerKit input/output and communication interfaces that can be found on the topside of the board.
Features:
- Operating voltage 5V (supplied from the Arduino Board)
- Ethernet Controller: W5500 with internal 32K buffer
- 2x TinkerKit Inputs, Outputs, and TWI Pins Each
- Connection speed: 10/100Mb
- Connection with Arduino on SPI port

Arduino的以太網盾2允許Arduino板連接到互聯網。它是基於WIZNET W5500以太網芯片。該WIZNET W5500提供了網絡（IP）堆棧能夠TCP和UDP的。它最多可支持8個同時套接字連接。使用以太網庫編寫連接到使用屏蔽互聯網草圖。以太網屏蔽2使用通過屏蔽延伸的長繞線頭連接到一個Arduino板。這樣可以使引腳佈局完整，並允許另一個盾在它的頂部堆疊。
有板載微型SD卡插槽，其可用來存儲文件用於服務在網絡上。它與Arduino的烏諾和Mega（使用以太網庫）兼容。板載的micro-SD讀卡器是通過SD庫訪問。當與此庫的工作，SS是在引腳4.盾的原始版本包含一個全尺寸的SD卡插槽;這是不支持的。
屏蔽還包括一個復位控制器，以確保該W5500以太網模塊正確上電復位。盾以前版本沒有的超級兼容，需要在開機後手動復位。最新版主板上公開Arduino的UNO董事會轉3 1.0引腳。以太網盾2有一個標準的RJ-45連接，並啟用了集成的線路變壓器和以太網供電，但請注意，這盾牌沒有配備內置的PoE模塊。 PoE模塊，將需要添加的是，必須加入的一個單獨的組件。這盾還提供了可在板的上部被發現了幾個TINKERKIT輸入/輸出和通信接口。
特徵：
- 工作電壓5V（從Arduino板提供）
- 以太網控制器：W5500內部32K緩衝區
- 2X TINKERKIT輸入，輸出和TWI插腳
- 連接速度：10 / 100Mb的
- 與Arduino的SPI端口連接
