New, made in Italy: Arduino Ethernet Shield 2 using W5500


Ardunio launch a new version 2 Ethernet Shield with our W5500 chip.

I think nice new features are:

  • W5500 for high performance Internet connectivity
  • Power over Ethernet (PoE) option
  • Lables for the Signals attached to Pin-Headers / Sockets
  • extra 3 pin In and Out with I2C and GPIO
  • Reset chip for most best compatibility says:
” … The Arduino Ethernet Shield 2 allows an Arduino Board to connect to the internet. It is based on the Wiznet W5500 Ethernet chip (datasheet). The Wiznet W5500 provides a network (IP) stack capable of both TCP and UDP. It supports up to eight simultaneous socket connections. Use theEthernet 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.

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.

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. …”

Thanks Arduino for selecting the W5500 here.
