NetWorker

NetWorker

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.

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.
