EasyEDA

CircuitMaker is not just a free EDA software tool from Altium, it’s also a community of creative people and design content, working together to invent circuits and electronics products for a better future. For turning great ideas into real products, you need design tools that won’t limit your imagination or hold you back. CircuitMaker has all the power you need to design high quality schematics and Printed Circuit Boards, with no artificial limits on layer counts or board area. Best of all it’s free. The CircuitMaker community is where you will find great reference designs, and be able to promote and rate other projects in the community. You can even set up teams for collaborative design efforts. We think you deserve better design tools, made specifically for you, to turn great ideas into reality. That’s why we’ve created CircuitMaker. Besides being a collaborative community for electronic design content, CircuitMaker is Schematic & PCB design software.

EAGLE is electronic design automation (EDA) software that lets printed circuit board (PCB) designers seamlessly connect schematic diagrams, component placement, PCB routing, and comprehensive library content. Bring your design to life with a wide range of PCB layout tools in EAGLE. Drag and drop reusable design blocks between your projects, complete with synchronized schematic and PCB circuitry. Validate your schematic design with a complete set of electronic rule checks, so your schematic can stay on track. All changes stay automatically in sync between your schematic and layout, so you can focus on the creative process. Control your design flow and avoid unexpected surprises with fully customizable PCB design rules and constraints. Worry-free libraries are ready for your next design. Find and place parts dynamically linked to our growing catalog.
