This version support micro SD card (TF card) to read and write The expansion board with a stackable design can be directly plugged into the Arduino. This is a clone without MCU on it and POE functions, but arduino stackable, achieve most functions for ethernet use. It uses the Ethernet library to write sketches which connect to the internet via a standard RJ45 Ethernet jack using the shield.

Specification:

• With this Ethernet Shield, your Arduino board can be used to connect to internet.
• Can be used as server or client.
• Directly plug puzzle board, no soldering required.
• Controller: W5100.
• This is the latest version of the Ethernet Shield.
• This Arduino Ethernet Shield which is based on the Wiznet W5100 Ethernet Chip gives you an easy way to get your Arduino Online.
• It is directly supported by Arduino official Ethernet Library.
• It adds a micro-SD card slot, which can be used to store files for serving over the network.
• It is compatible with the Arduino Duemilanove (168 or 328), Uno as well as Mega (1280/2560) and can be accessed using the SD library.
• The Wiznet W5100 provides a network (IP) stack capable of both TCP and UDP.
• It supports up to four simultaneous socket connections.
• Use the Ethernet library to write sketches which connect to the internet using the shield.
• Fits all version of Arduino Main board,2009,UNO, mega 1280, mega 2560.
• Size: 7cm x 5.4cm x 2.4cm – 2.76inch x 2.12inch x 0.94inch.
• MAC address: 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }

Features:

The shield contains a number of informational LEDs:

• PWR: indicates that the board and shield are powered
• LINK: indicates the presence of a network link and flashes when the shield transmits or receives data
• FULLD: indicates that the network connection is full duplex
• 100M: indicates the presence of a 100 Mb/s network connection (as opposed to 10 Mb/s)
• RX: flashes when the shield receives data
• TX: flashes when the shield sends data
• COLL: flashes when network collisions are detected

Package Include:

• 1 x Ethernet Shield W5100 Network Expansion Board Arduino W5100 Ethernet Shield Module With SD TF Card Holder For Arduino UNO UNO R3 Mega 2560
