Arduino® Ethernet Shield 2

The Arduino® Ethernet Shield 2 easily connects your Arduino board to the internet, enabling you to control your projects remotely. With a few simple steps, you can integrate the shield into your network using an RJ45 cable (not included), and begin connecting to the internet.

This shield utilizes the Wiznet W5500 Ethernet chip, providing a robust network (IP) stack that supports both TCP and UDP protocols. It allows up to eight simultaneous socket connections, making it an ideal solution for connected projects. The shield also includes an onboard micro-SD card slot for storing files that can be served over the network, accessible through the SD Library.

Key Features

• Microcontroller: Wiznet W5500 Ethernet chip

• Ethernet Connection: RJ45 port with integrated line transformer and Power over Ethernet (PoE) support (PoE module sold separately)

• Compatibility: Works with Arduino Uno and Mega

• Power: Supports Power over Ethernet (PoE) for extraction of power from Ethernet cable (IEEE802.3af compliant)

• Micro-SD card slot for storage (accessible via SD Library)

• SPI Communication: Communicates with Arduino via SPI bus (pins 10, 11, 12, and 13 on Uno, pins 50, 51, 52 on Mega)

• LED Indicators:

• ON: Indicates power to the board and shield

• 13: Standard built-in LED for Arduino

• ACT: Flashes during RX/TX activity

• LINK: Flashes when there is network activity

• Reset Button: Resets both the W5500 Ethernet chip and the Arduino board

• PoE Module: Optional (sold separately) and supports 36V-57V input, providing 12V output with high efficiency

Technical Specifications

• Input Voltage: 7-12V (from Arduino)

• Power Consumption: Varies depending on connected devices

• SPI Pins (Uno): Pins 10, 11, 12, 13

• SPI Pins (Mega): Pins 50, 51, 52 (Pin 10 used to select W5500, Pin 4 for SD card)

The Arduino Ethernet Shield 2 is fully open-source, offering flexibility for customization and integration. Whether you're building an IoT application, creating a networked sensor, or just learning about the internet of things, this shield is a great choice for getting your Arduino projects connected to the digital world.
