There are a lot of definitions of Open Source Hardware floating around these days. We like Freedom Defined's Open Source Hardware (OSHW) Definition v1.0:
"Open Source Hardware (OSHW) is a term for tangible artifacts -- machines, devices, or other physical things -- whose design has been released to the public in such a way that anyone can make, modify, distribute, and use those things."
We currently use Freedom Defined's Open Source Hardware Definition v1.0 as our official guideline.
Sound like a lot? Don't worry, we'll help sellers select the best licenses and give buyers a clear breakdown of what they are getting. And of course, there are always exceptions. As long as you are in line with the spirit of open source hardware, you are probably ok.
It can be a little tricky digging through all of the different licenses. See our OSHW license guide to see a breakdown of the most popular licensing options and their requirements for hardware, software, and documentation.
In order to make the community as dynamic as possible, we have one special requirement for all items on InMojo. If you referenced any InMojo item in the design or execution of your item, we ask that you attribute that item as source.
