ARDUINO ETHERNET SHIELD 2, ARDUINO A000024

The Arduino Ethernet Shield 2 connects your Arduino to the internet in mere minutes. Just plug this module onto your Arduino Board, connect it to your network with an RJ45 cable (not included) and follow a few simple steps to start controlling your world through the internet. As always with Arduino, every element of the platform – hardware, software and documentation – is freely available and open-source. This means you can learn exactly how it's made and use its design as the starting point for your own circuits. Hundreds of thousands of Arduino Boards are already fueling people’s creativity all over the world, everyday. Join us now, Arduino is you! 

• 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 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 current Shield supports a Power over Ethernet (PoE) module designed to extract power from a conventional twisted pair Category 5 Ethernet cable. 

PoE module features as follows: 

• IEEE802.3af compliant
• Input voltage range 36V to 57V
• Overload and short-circuit protection
• 12V Output
• High efficiency DC/DC converter: typ 85% @ 80% load
• 1500V isolation (input to output)

• The Shield provides a standard RJ45 Ethernet jack.
• The reset button on the Shield resets both the W5500 and the Arduino Board.
• The Shield contains a number of information LEDs:
• ON: indicates that the Board and Shield are powered
• 13 is the Arduino standard built in LED
• ACT: flashes when RX or TX activity is present
• LINK: indicates the presence of a network link and flashes when the Shield transmits or receives data

This shield also hosts Tinkerkit compatible connectors as follows: 

• 2 TinkerKit connectors for two Analog Inputs (in white), connected to A2 and A3.
• 2 TinkerKit connectors for two Aanlog Outputs (in orange in the middle), connected to PWM outputs on pins D5 and D6.
• 2 TinkerKit connectors for the TWI interface (in white with 4 pins), one for input and the other one for output.
