Looking for commercial-grade CAD design software you can depend on for smooth sailing from design through manufacturing? How about a free CAD design software with features, not fluff?

Look no further — PCB123 is the only CAD design software that ensures a smooth transition from design through manufacturing, and it's absolutely free.

Just released: By integrating Sunstone's new OneQuote functionality, Version 5.5 has taken the user experience to a whole new level. PCB123 v5.5 gives you, the designer, new manufacturing capabilities to make you even more efficient - ultimately saving time and money. 

    • Enhanced User controls (Faster rendering, smoother drag and drop, more zoom control, unified control panels) *NEW
    • Unrestricted Drill Sizes on your PCB123 orders
    • Slots and Cutouts available on boards and in parts definitions
    • Save time with 750k+ fully-defined, qualified parts
    • Keep layout, schematic, and BOM in-sync and up-to-date, automatically
    • Quote in real-time and order from within the application
    • Integrated schematic and layout views
    • Be confident in manufacturability with built-in DFM, DRC, and parts availability
    • View all features

"The improved Parts and Display panels in the new version are really good.  This is a nice improvement in PCB123.  Also, being able to see the symbol/footprint of a part is a great feature.  On the Display, being able to center on the location of the board by d-clicking is huge!  The User Preferences options that have been added to the Edit Panel are intuitive and work well."  - PCB123 User, Adam Andrade, Qualcomm Inc.
