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

ProtoFlow is an AI-native desktop electronic design automation (EDA) tool for schematic capture and PCB design. Describe a circuit in plain language to create an editable first draft, search real electronic parts and footprints, inspect datasheets, clean up wiring, and continue manually in familiar schematic and board editors. ProtoFlow supports ERC/DRC review, 3D board inspection, Git-backed versioning and visual diffs, comments and collaboration, plus manufacturing outputs including Gerber, drill, BOM, and placement files. Designs remain normal editable geometry, and users should verify symbols, footprints, connections, and manufacturing data before production. ProtoFlow can read and write native KiCad files and export to established EDA workflows. A free plan is available without a credit card, with paid options for higher AI usage. It is built for hardware engineers, makers, students, educators, researchers, and electronics startups.

Pros & Cons from Real Users

Pros

  • Looks like a nice program from what I could see of it. I would give it a much better rating if it worked in a virtual machine.
  • Well as a first time use i started to use EasyEDA which didn't work for me at all. Hard to use program for a user seeing the program the first time. Also tried other options and programs like Altium Designer and i didn't make it work so this program CircuitMaker as a first time user has all the pros EasyEDA to use free and gets the job done. As i went to the manufacturer export files worked so no problems there.

Cons

  • When I try to make a new schematic or PCB drawing I always get this error: HRESULT: [0x887A0004], Module: [SharpDX.DXGI], ApiCode: [DXGI_ERROR_UNSUPPORTED/Unsupported], Message: Unknown at 30945C72. AdvSch.dll, Base Address: 2F6A0000.
  • The only thing i have to add here is the parts database is a bit low for now.
