CircuitMaker

CircuitMaker is a free PCB design tool by Altium intended for hobbyists and open-source hardware communities. It offers up to 16 signal layers, with advanced features like design rule checks and 3D board previews. The integrated library contains community-shared components, while users can contribute their designs. A built-in collaborative platform lets multiple users comment or fork projects. Though somewhat streamlined compared to Altium Designer, CircuitMaker retains professional-grade capabilities, letting makers produce high-quality boards for personal or small-scale commercial projects at no cost.
