There are a few drawbacks to this ENC28J60 Ethernet shield – the official Arduino Ethernet shield has a 10/100 Mbps connection where the Microchip-powered shield is limited to 10 Mbps.

The problem with using it along with Arduino-based gadgets is that you then need to use something like an Ethernet shield to provide the network connection.

An UNO Shield that stacks onto Arduino boards (or Arduino-like boards such as Mbed) and provides an SPI interface to data packets that are sent or received using the EtherCAT protocol.

The Arduino Ethernet Shield is equipped with a microSD card holder, accepts a working voltage of 5V and is supported by either the Arduino Uno or Mega development boards.
