Find the core components in ProtoFlow
Use the exact manufacturer part number to find symbols, footprints and linked 3D models. This is the cleanest starting point when recreating a circuit block or designing a compatible board.
Using the reference design
Open the manufacturer resource page and select the file set for your board revision. The package may use KiCad, EAGLE, Altium, Cadence or a manufacturer-specific format. Review the manufacturer’s licence and release notes before copying circuitry into a product.
ProtoFlow indexes these resource links for discovery. Arduino owns and publishes the linked files; ProtoFlow does not mirror, modify or verify them. The manufacturer page is the source of truth for revisions and usage terms.
