Call for Contributions

Log in to review your contributions.

Pi and More 11½ will take place on Saturday, April 6th, 2019 at Hochschule Niederrhein in Krefeld. We expect about 300 visitors.


We are looking for people and groups who would like to present a project or topic. These can be own or third party developments (e.g. hardware and software projects) or general topics (e.g. first steps with the Raspberry Pi, programming, system internals, hardware tutorials). Contributions around the Raspberry Pi are just as welcome as contributions about (other) embedded systems and microcontrollers. The event is aimed at beginners as well as professionals, so we look forward to very simple, small projects as well as workshops for professionals.

We offer
