RoarKit Nano W5100 Ethernet LAN Network Module

This add-on module allows you to connect the Arduino Nano to the internet. You get all of the benefits of using the Arduino Nano. It is fully assembled with long pin headers so you don need to purchase and solder the headers separately. you get the same stackable benefits as the Arduino shields and can run the same code. It is based on the Wiznet W5100 Ethernet chip which a network (IP) stack capable of both TCP and UDP. Use the Ethernet library to write sketches which connect to the internet using the add-on module. The ETHERNET-NANO connects to an Arduino Nano using female long wire-wrap headers which extend through the board for the breadboard connections. This keeps the pin layout intact and allows another add-on module to be stacked on top or bottom.
