An advanced web server with a micro
An Internet connection would be a valuable addition to many projects, but often designers are put off by the complexities involved. The ‘NetWorker’, which consists of a small printed circuit board, a free software library and a ready-to-use microcontroller-based web server, solves these problems and allows beginners to add Internet connectivity to their projects. More experienced users will benefit from features such as SPI communications, power over Ethernet (PoE) and more.

CAM/CAD data for the PCB referred to in this article is available as a Gerber file. Elektor Members can exclusively download these files for free as part of their Membership. Gerber files allow a PCB to be produced on an appropriate device available locally, or through an online PCB manufacturing service. Elektor recommends its business partner Eurocircuits as the company of choice for its own prototypes and volume production in selected cases.
Update, November 11, 2010
We're sorry no ready-programmed microcontrollers can be supplied for this project. The microcontroller is an SMD device requiring special handling soldering techniques. Ready built and tested boards for the Networker are available and come with a ready-programmed micro fitted.
The BOM (Bill of Materials) is the technically exhaustive listing of parts and other hardware items used to produce the working and tested prototype of any Elektor Labs project. The BOM file contains deeper information than the Component List published for the same project in Elektor Magazine. If required the BOM gets updated directly by our lab engineers. As a reader, you can download the list here.
