A000024,ETHERNET SHIELD 2 5V

The Arduino Ethernet Shield 2 enables quick and easy internet connectivity for your Arduino projects. Simply plug the module onto your Arduino board, connect it to your network using an RJ45 cable (not included), and follow simple instructions to control devices over the internet. The platform's open-source nature allows users to explore and customize its design, fostering creativity across the globe.

Requires an Arduino Board (not included)

Key Specifications

• Operating Voltage: 5V (supplied from the Arduino Board)
• Ethernet Controller: W5500 with internal 32K buffer
• Connection Speed: 10/100Mb
• Connection with Arduino: SPI port

Technical Details

• Chipset: Based on Wiznet W5500 Ethernet chip, providing a network stack capable of both TCP and UDP, supporting up to eight simultaneous socket connections.
• Pin Layout: Uses long wire-wrap headers to maintain the original pin layout, allowing for stacking with other shields.
• RJ-45 Connection: Standard connection with integrated line transformer and Power over Ethernet (PoE) enabled.
• Micro-SD Card Slot: For storing files to serve over the network; accessible through the SD Library.
• Reset Controller: Ensures proper reset of the W5500 Ethernet module on power-up.
• Compatibility: Compatible with Arduino Uno and Mega using the Ethernet library.

Power over Ethernet (PoE) Module Features (separate component)

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

Connection and Usage

• • SPI Communication: Arduino communicates with W5500 and SD card using SPI bus through ICSP header.
  • Pin Assignments:
    • Uno: Digital pins 10, 11, 12, and 13 for W5500 and SD card.
    • Mega: Pins 50, 51, and 52 for W5500; pin 4 for SD card.

Note: Pin 10 is used to select W5500, and pin 4 for the SD card; these cannot be used for general I/O.

LED Indicators

• Power ON: Indicates the board and shield are powered.
• Built-in LED (Pin 13): Standard Arduino LED indication.
• Activity Indicator (ACT): Flashes during RX or TX activity.
