Crazy Circuits

Crazy Circuits is a project to create Lego-compatible circuit kits and modules by Brown Dog Gadgets.

Circuit Kits and Modules

The Circuit Kits section has finished zip files with manufacturing files and documentation.


The Developers section has resources for hardware designers to create new modules.


The hardware designs in this repository are distributed under the CERN Open Hardware License v1.2. We have included a copy of the LICENSE file.

You may see, change, and share the source of these files. You may order and assemble your own boards from these hardware designs. We recommend the OSH Park board service.

If you make changes, you must make those changed hardware files available under the same terms of the license. We accept pull requests if you'd like to add a module to our list of modules!
