Although defunct, 123D Circuits leaves a lasting legacy in the field of EDA. It proved that complex hardware design tools could operate effectively within a web browser. Its DNA is clearly visible in , which remains one of the most popular tools for teaching Arduino and basic electronics today. Furthermore, it pioneered the concept of "ECAD-MCAD" integration—linking electronic and mechanical design—which is now a cornerstone of the Autodesk Fusion 360 platform.

It succeeded wildly in its mission to make circuits accessible but fell victim to Autodesk's broader strategy to own both the absolute beginner (Tinkercad) and the professional (Fusion 360/Eagle), leaving little room for a mid-range tool. Although defunct, 123D Circuits leaves a lasting legacy
Autodesk 123D Circuits, launched in partnership with Circuits.io, provided a web-based, collaborative environment for designing, simulating, and ordering custom PCBs, functioning as a "virtual breadboard" [1, 2, 4, 13]. The platform featured real-time Arduino simulation and, in 2017, its capabilities were migrated into Tinkercad Circuits for beginners and Autodesk Fusion for advanced users [5, 16, 22]. You can learn more about the transition from Autodesk on their product blog. The platform featured real-time Arduino simulation and, in
By 2018, the original 123D Circuits website (circuits.io) was redirected to Tinkercad. Existing user projects were migrated, but many advanced features were gone. The community mourned—the "pro-sumer" sweet spot was lost.
Before 123D Circuits, designing and prototyping electronics was fragmented. You'd sketch a schematic on paper, design a PCB in expensive, complex software like Eagle or Altium, then order physical boards—a slow, costly process for beginners. Meanwhile, Arduino and the maker movement were exploding.
In 2016-2017, Autodesk began consolidating. The entire was retired. 123D Design was replaced by Tinkercad. For electronics, Autodesk announced that 123D Circuits would be rebranded and integrated into a new platform: Tinkercad Circuits .
