Free Hardware, more commonly, Open/Open-Source Hardware refers to devices or components on which detailed schematics and/or other information are available to anyone who would desire to improve or change them. The term most often means that some of the information about the hardware is easily discerned so that others can make it - coupling it closely to the maker movement. Hardware design (i.e. mechanical drawings, schematics, bills of material, PCB layout data, HDL source code and integrated circuit layout data), in addition to the software that drives the hardware, are all released under free terms. The original sharer gains feedback and potentially improvements on the design from the Free/Open Source hardware community.
