Schematic Pin Counter

Total pin count is how PCB layout effort gets scoped. Drop a KiCad (.kicad_sch) or Eagle (.sch) schematic — or a KiCad/Protel/PADS netlist — and get per-component counts and a total instantly. Power symbols (GND/VCC) are excluded automatically, and everything runs in your browser.

Drop schematic / netlist files here

KiCad .kicad_sch · Eagle .sch · netlists (.net, KiCad/Protel/PADS) · ZIP — counted in your browser, never uploaded.

How to use

Drop schematic (.kicad_sch, Eagle .sch) or netlist (.net) files into the box above. Multiple files and ZIPs work too.
Review the total plus per-file and per-component counts. DNP or missing-library cases are flagged in the notes column.
Need a layout quote? The button below the result carries your files straight into the quote console.

FAQ

Why count pins?

Total pin count is the standard measure of PCB layout effort — it reflects routing complexity better than component count, so it's useful for scoping a design job before requesting a quote.

What about Altium .SchDoc?

Altium schematics are a binary format that can't be parsed in the browser. Upload them to our quote console and the server counts pin records precisely (cross-validated against KiCad).

It says power symbols were excluded.

GND/VCC-style power symbols aren't mounted parts, so they're excluded automatically — the standard convention for sizing layout work.

I get a sub-sheet warning.

Hierarchical KiCad designs span multiple sheet files. Drop all related .kicad_sch files together and they'll be summed.
