Microsoft .NET Gadgeteer is an Open Source rapid prototyping platform with an emphasis on creating small electronic or embedded hardware devices. It brings the concept of software encapsulation to hardware components, enabling the solderless assembly of electronics using a selection of hardware modules. There is some focus on rapid prototyping of the physical enclosure fabrication using computer-aided design.
The .NET Gadgeteer core is built upon the .NET Micro Framework, currently version 4.1 and originates from Microsoft Research in Cambridge, UK. The core libraries are published under the Apache License 2.0 License and the hardware designs are under the Creative Commons 3.0 License. The core source code is publicly available from the codeplex source repository.
