# PartSpark
> PartSpark is an AI part generator for PCB designers: it reads the real manufacturer datasheet and builds a linked schematic symbol and a PCB footprint (the manufacturer's recommended land pattern when the datasheet has one, IPC-7351B conventions otherwise), plus a 3D STEP/WRL model on paid plans, with a reviewable pin map and notes on anything it assumed. Typical generation time is about a minute. Inputs: a part number, datasheet URL, PDF, or a photo of the pinout page. Exports: KiCad (.kicad_sym/.kicad_mod), Autodesk EAGLE (.lbr), Altium Designer (.SchDoc/.PcbDoc import bundle), and Cadence Allegro (EDIF symbol and footprint conversion bundle). Built by the team behind ProtoFlow (https://www.protoflow.ai) on the same generation engine.
Key facts:
- Generation runs in the browser; no install is required. Signing in (free) is required so allowances can be enforced; a ProtoFlow account works as-is.
- Inputs: manufacturer part number, datasheet URL, up to six attached PDFs/images (20 MB each, 22 MB combined).
- Outputs: pin-linked schematic symbol + PCB footprint, full reviewable pin map, warnings for anything uncertain, optional 3D STEP + WRL model (paid plans), per-EDA export bundles.
- Known limits: slotted (oval) and non-plated holes are not supported yet; the generator stops rather than guessing when a datasheet does not dimension the package; KiCad symbols link footprints under the library nickname ProtoFlow.pretty.
- Generated parts can be revised with plain-English feedback ("pin 4 is GND, not NC") instead of regenerating from scratch.
- Free accounts receive daily and monthly generation allowances shared with ProtoFlow.
- Free tier includes monthly generations; paid ProtoFlow plans add more generations, premium AI models, and 3D generation.
