Free tools for the boring half of PCB design.
Library work is where board schedules quietly disappear: the part nobody has modeled, the land pattern that has to be transcribed from a scanned drawing, the forty-eight-pin symbol with its electrical types set by hand. These run in the browser, output real files for KiCad, EAGLE, Altium, and Allegro, and show you the full pin and pad tables so you can verify every result against the datasheet.
KiCad Footprint Generator
Turn a part number or datasheet into a .kicad_mod land pattern, built to IPC-7351B with the full pad table shown for verification.
Open the tool →KiCad Symbol Generator
Turn a part number or datasheet into a .kicad_sym schematic symbol with correct pin names, numbers, and electrical types.
Open the tool →Datasheet to Footprint
Upload a datasheet PDF — or just a photo of the package drawing — and get a land pattern for KiCad, EAGLE, Altium, or Allegro.
Open the tool →Need the whole schematic, not one part?
These tools solve the single-component problem. The free ProtoFlow desktop app solves the one above it: describe a circuit in plain English and get an editable schematic with real LCSC, DigiKey, and Mouser parts attached, run ERC and DRC on it, and export a native KiCad project. Free on macOS, Windows, and Linux.
