Nanode - a Network Applications Node based on Arduino technology

thingiverse

Nanode offers the lowest cost web connectivity for microcontrollers and smart sensor networks, compatible with Arduino's programming environment. It combines ATmega328, ENC28J60 ethernet controller, and a magjack ethernet connector on a small PCB. All components are conventional through-hole, making assembly accessible to those with basic soldering skills for under £20 ($32). The Nanode has additional I/O connectors that allow it to be directly plugged into a standard breadboard for easier prototyping. It's compatible with most Arduino shields and can be connected to a low-cost wired serial bus, enabling distributed applications in home automation or energy monitoring systems. As an affordable platform, Nanode is perfect for introducing web connectivity and networking in college or Hackspace projects. It allows the development of remote monitoring and control applications using services like Pachube. Nanode is based on Tuxgraphics' earlier ATmega/ENC28J60 design and firmware. Build instructions are available on the Sustburbia blog, while more details including parts lists and PCB prices can be found on the London Hackspace Wiki. A spreadsheet of parts lists from Cool Components and Rapid Electronics in the UK is included for bulk orders. Andrew Lindsay has written a firmware library that handles ATmega/ENC28J60 commands, featuring examples of a Twitter client, DNS queries, and Pachube client for CSV data retrieval. The library and more details can be found on his blog.
