## Article

The `Arduino Ethernet Shield` is the perfect start point for beginner who want to explore network connectivity for their Arduino Projects. Its compatible with `Arduino Uno` and `Arduino Mega`. Unfortunately the original `Arduino Ethernet Shield 2` prices are spicey, so many of us try to get hands on to cheaper alternatives.

A famous and cheaper alternative is the chinese `Arduino Ethernet Shield Clone` based on the `W5100` chip. Compared to the `ENC28J60` module, the `W5x00` chip series have integrated *TCP/IP Stack* and work with the [Arduino Ethernet Library](https://github.com/arduino-libraries/Ethernet). So what can go wrong?
