We love CircuitMaker because it offers the possibility of our community to contribute easily. We can promote our board model by sharing a simple link to a release. Users can produce our designs themselves or by forking it to adapt it to their needs.

PRODUCT WITH CIRCUITMAKER
POWERFUL FREE ECAD TOOL AND ALTIUM 365 SERVICES FOR EVERYONE
Being a part of the Open Source Hardware Community we think you deserve better design tools, made specifically for you and the community you belong to. That’s why we’ve created CircuitMaker; a free PCB Design Software, built on Altium Designer technology. With a streamlined interface and powerful engine to boot, you’ll never have to worry about your software holding you back. See what you can do with CircuitMaker.
UNLIMITED ACCESS & FREE TO USE
Typically, free EDA software comes with design restrictions that render it useless for any real project. With CircuitMaker, you get the full power of 16 signal layers plus 16 plane layers, and no restrictions to the PCB dimensions. Also, with no commercial clause restrictions, you are free to earn revenue with your design.
MASSIVE COMPONENT LIBRARY
CirucitMaker is built on a community library with hundreds of thousands of components, all backed by the comprehensive, realtime Octopart database. Placing components in CircuitMaker designs is as easy as searching by manufacturer part number or by design parameters. You can also add your own custom parts and mechanical components.
SHARE & COLLABORATE
Supported by Altium 365 platform you can create and work on projects with your team or invite other community members to work with you on the design. Harness the power of teams to get projects done faster. Projects can be forked and modified at any time so you can build new designs using the community wisdom and experience without having to start from scratch.
NATIVE 3D™
Altium Native 3D™ technology means that when you’re in the PCB editor, just hit the 3 key and you can immediately see the PCB layout in full interactive 3D. It will show any component clearance violations and you’ll also even know what the overlap distances are, so you can get your designs right — and to fit the box — the first time.
ONE-CLICK MANUFACTURING
(coming soon on Altium 365)Once you’ve finished your design, release the project to the community. From there, you can download the gerbers and send them off to any PCB manufacturer. To make it easy, we’ve partnered with select manufacturers to provide a one-click manufacturing button that can directly send your board for quoting — either bare board prototype or full PCB fabrication and assembly—at the best possible price.
PUSH-AND-SHOVE ROUTING
Routing capabilities are robust in Circuitmaker. The interactive routing modes include obstacle avoidance, hug, hug-n-push, and obstacle ignore. The push modes will push other traces and vias, as well as hop-over. You can even route differential pairs and interactively add accordions to nets that need that extra length for signal delays.
MULTI-SHEET SCHEMATIC EDITOR
CircuitMaker uses the same easy-to-use schematic editor as Altium Designer. You can create complex multi-sheet designs, use hierarchical design blocks, and generate SmartPDF™ outputs from your project.
TOPOLOGICAL AUTO-ROUTER
The Situs™ topological autorouter works in concert with your design rules to help you get the board done fast. With BGA and SMT fanout, parallel memory, hug, and via optimization, it’s easy to use Situs to get working results really fast. You can also interactively route multi-nets or single nets, or use manual routing with auto-complete.
DRC/DFM VALIDATED OUTPUTS
When you’re ready to turn your virtual design into a real physical board, CircuitMaker will generate industry standard CAM outputs. You can choose Gerber and NC Drill, or ODB++, or both. IPC test point reports and all other necessary outputs for professional manufacturing can be generated as well, and all this through a succinct release process that ensures your board passes design rules checks for DFM and assembly.

Design Without Restrictions
If you design printed circuit boards, or you would like to, Osmond PCB for Macintosh puts great power and flexibility within your reach. Artificial limits and restrictions are banished. You can now design boards of any size and shape and with as many layers as you want. With a spatial resolution of 10 nanometers (0.00001 mm), Osmond gives you all the precision you need. You can place parts anywhere on the board with any orientation. You can also run traces of any width along any path and at any angle.
Flexible Features
At times you may wish to work in Metric units. At other times, Imperial units may be prefered. Osmond supports both. You can even work with both Metric and Imperial units on the same design, seamlessly switching from one to the other to suit your needs.
If you bring a design from a schematic capture application, Osmond will import the part list and net list and maintain adherence to specified design rules thoughout the design process. However, you can also start with no part lists or no net lists at all and generate the design in a completely informal, ad-hoc manner. Osmond supports your design style, whatever it may be.
Of course, Osmond provides tools that let you move and re-orient parts, connect and route traces, modify existing traces, and edit pads and pad-stacks. But you can also make your traces curved and make PCB labels using characters from the Mac font library.
Osmond provides a flexible grid to help guide your work. But you can also import any PDF document to serve as a background image. This can be especially handy if you need to match your design to an existing mechanical drawing or if you need to partially retrace an existing design.


Integrated into Osmond is a Parts Editor that lets you easily define new part types or modify existing part types. Both thru-hole and surface mount part types are supported as well as round, oval, and rectangular pad shapes.
Osmond supports ground or signal planes using several methods, and also allows you to define arbitrary copper flood areas.
In addition to the signal layers, Osmond provides two silkscreen layers, two solder mask layers, and multiple auxiliary layers that you can use, for example, to show dimensions or special fabrication notes.
To further enhance your design capability, Osmond provides scripting support, using the very powerful Lua programming language.
Finishes
Osmond has tools that let you check that your design is free from error and that it meets all your specified design rules.
Once your design is complete, Osmond can produce standard Gerber (RS-274X) files and Excellon drill files that fabricators use to make your boards. If you desire more control over the fabrication process, Osmond will also let you define your own panels containing either multiple copies of your design or several different designs. Do-it-yourself fabricators may prefer Osmond's Postscript output, which can be directly printed on transparencies that can then be used to etch the PC board.
