About
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.

About
Copperhead is an open source AI engineering platform that helps hardware teams design, verify, and ship circuit boards. You describe a change or provide a product brief, and the agent edits real KiCad files, updates the documents that reference them, and runs KiCad’s own checks until they pass. Its end-to-end workflow moves through specification, architecture, parts selection, schematic, layout, outputs, firmware, and development planning, with each stage required to leave a real artifact on disk before the next begins. Gates verify budgets, subsystem reasoning, datasheet-backed part numbers, ERC-clean schematics, DRC-clean layouts, generated Gerbers, firmware sources, and written bring-up plans. Copperhead is also designed for existing boards: point it at a KiCad repository, initialize the project, and ask for changes. Edits are surgical changes to KiCad source files, keeping diffs small and reviewable while untouched portions remain unchanged.
