The Freedom to Build Without Limits.

Give Inky a photo and describe what you want. It drafts a schematic, selects components, and generates a PCB layout you can inspect and change.

Ever seen a piece of hardware and wondered how it works, or how you'd build your own version?

Software can start with a screenshot and an idea. We think hardware should be just as approachable.

Five boards in a row, each paired with a small photo of the cat, card, drone, handheld, or macro pad.

Now you can give Inky a photo and describe what you want to build. It can draft the schematic, select components, and generate a PCB layout with footprints, placement, and routing.

We started with the Joule Thief Cat by Tilde Industries, a little cat-shaped circuit with glowing eyes powered by a single AA battery. From photos of the front and back, Inky worked through the electronics, recreated the board's shape, and arranged the components to bring the design together.

Next, we tried a Tetris business card and a handheld inspired by Adafruit's PyGamer. One fits a playable game onto a business card. The other brings together a display, buttons, and controls. Inky translated both references into actual PCB layouts, with components and connections you can inspect and change.

We also tried two very different designs: a drone inspired by Bitcraze's Crazyflie and a custom macro pad. For the drone, Inky recreated the X-shaped board and fitted the electronics into its compact center. For the macro pad, it arranged the mechanical switches, two rotary encoders, and USB-C connection to follow the original reference.

Five boards alone: a cat with glowing eyes, a card labeled NEXT, an X-shaped drone, a handheld, and a switch pad.

Hardware has always advanced through people learning from existing work and building on each other's ideas. We believe everyone should have that same freedom, whether they're starting with an idea, an existing design, or simply a photo of something that inspires them.

The freedom to build what inspires you.

Stop searching for PCB footprints.

Inky turns a part number or datasheet into a schematic symbol and PCB footprint, then builds the dual-motor driver board.
