Full electronics design suite for schematic capture and PCB layout.

PriceFree

Why we recommend it

Industrial designers working on connected products eventually hit the electronics boundary — this covers schematic through to manufacturable Gerbers, with a 3D viewer for enclosure fit checks.

Strengths

  • Complete schematic-to-PCB workflow
  • 3D board viewer for enclosure clearance checks
  • No layer or board-size limits, unlike free commercial tiers

Drawbacks

  • Genuinely steep learning curve if you're new to PCB design
  • Component library conventions take time to learn
  • Overkill unless you actually need electronics
