Launch notes

ECAD Workbench is launching with free electronics calculators.

The first public release focuses on practical first-pass design checks for schematic and PCB work, with equations, assumptions, limitations, examples, and related workflow links.

See available calculators About the project
ECAD Workbench branded circuit-board processor with illuminated signal traces

The first public release is simple: useful free calculators for electronics design checks, with more workflow-focused tools planned over time.

What would make this more useful during real design work?

The most useful launch input is specific: incorrect assumptions, confusing wording, missing examples, awkward mobile behaviour, or calculator workflows that would save engineering time.
