One place to search
Look across distributor catalogs like LCSC, DigiKey, and Mouser at once instead of opening a tab per vendor.
Use case
Search every distributor at once.
Find the parts you need from one place — with real symbols and footprints — instead of bouncing between datasheets, catalogs, and browser tabs.
One search, many catalogsReal symbols + footprintsOrderable parts

01 | THE PROBLEM
Sourcing breaks your flow
01
Every part means another round of datasheet-and-catalog tab juggling.
02
A symbol whose footprint doesn't match the real part costs you a respin.
03
Generated or placeholder parts you can't actually buy aren't a head start.
02 | HOW PROTOFLOW HELPS
Symbol and footprint together
Import a real part and get its symbol and footprint tied to an orderable part number.
A buildable BOM
Grounding the schematic in real, in-stock parts is what makes it trustworthy enough to lay out.
03 | HOW DISCOVERY WORKS
1Search
Search across catalogs
Look up a part by name, value, or function across distributor catalogs in one search.
2Import
Import the real part
Drop in the component and its symbol and footprint arrive together, tied to a part number.
3Build
Keep designing
Continue with parts you can order, then export a BOM-ready project.
04 | FAQ
Which distributors does it search?
ProtoFlow pulls real parts from distributors like LCSC, DigiKey, and Mouser, so your schematic maps to orderable components with known packages.
Do I get the footprint too?
Yes — importing a real part brings its symbol and footprint, so what you draw matches what you solder.
Does this work inside the editor?
Yes, part discovery lives in the editor, so you do not leave your design to find a component.
