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.

With Ethernet connectivity, your Arduino projects can communicate with other devices over a network, access online services, and even be controlled remotely via the internet.

Arduino have taken the tiny wraps off of the official ethernet shield for their open-source prototyping platform, which adds network connectivity to the device.

It’s no secret that Ethernet shields for the Arduino are a little expensive. With the official Ethernet shield selling for about $50 and other options not much cheaper, there’s a lot of room ...

Single-pair Ethernet is a communication standard that combines data and power on one unshielded twisted pair, for industrial installations over exiting and vehicle installations, for example, and ...

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.

There is also a “Cloud Flash” feature to program networked-enabled devices like the Arduino Ethernet or Arduino & Ethernet Shield.
