In the original thread there are original files of Eagle so everyone can change the project a little to fit individual needs (i.e. another Ethernet socket etc.). The module can be used to retrofitting the microcontrollers in Ethernet.
The system is based on a project from tuxgraphics.org: An AVR microcontroller based Ethernet device, where you can find all necessary information.
The ENC28J60 has many advantages: Tx/Rx, MAC and PHY in one small chip. It is a perfect s for hobby applications.
UDP application is used to send commands to the microcontroller. IO interfaces and analog to digital converter inputs are part of the project, that makes work with this device really easy and comfortable, since only one relay is to control the switch.
