An open part library — actually curated

Tired of parts that don't match the datasheet?

Every part here is one we've verified by hand. Real pin names, real ratings, a SPICE model that actually simulates, and a 3D model that matches the footprint. No dead LCSC numbers. No wrong pad counts. No "close enough."

Why this exists

You shouldn't have to reverse-engineer a component to use it.

You've done it: pulled a symbol with the pins swapped, a footprint with the wrong pad count, a value that was never in stock. Then the board comes back and the LED's backwards. This is the library we wanted — small, honest, and correct.

Verified, not scraped.

Every part is hand-checked against its datasheet — pins, ratings, package, footprint. If it's here, it's real and it's in stock.

Search by what it does.

Ask for "something to blink an LED" or "a connector rated 20 A" and get parts by function, not by guessing part numbers.

Everything to ship.

3D model, SPICE, labelled pins & pads and the datasheet — together. Your sim matches your board matches reality.
