Flux brings public parts and team library workflows into the same environment where the AI hardware engineer works on a device. ![A PCB design in the Flux editor.](https://www.flux.ai/p/assets/other-pages/landing/69a7ca6fbe02d8b52116fac9_step-2.png) 01 Find a part Search the public library for electronic parts with live pricing and availability. The library includes more than 734,000 public parts. ![An electronics design workspace in Flux.](https://www.flux.ai/p/assets/other-pages/landing/69a7ca7aa6aca7844d7edea1_step-3.png) 02 Connect design data Use a part with its schematic symbol, PCB footprint, and corresponding 3D model. The footprint maps the part to its 2D board layout. ![A hardware design request in the Flux interface.](https://www.flux.ai/p/assets/other-pages/landing/69a7cb5aa7af777b23f116c0_ste-1.png) 03 Create or import a part Use AI to create or import a part from its manufacturer part number, datasheet, or manufacturer page. The workflow can also check for duplicates. [ START DESIGNING WITH AI ](https://flux.ai/signup) ## Library coverage for component selection Flux has 734,000+ public parts with live pricing and availability. The library supports component selection with data that connects to the design.

A connected part record keeps that design data together. See the [PCB footprint library guide](https://www.flux.ai/p/blog/pcb-footprint-library-management) and [PCB footprint library management](https://www.flux.ai/p/blog/pcb-footprint-library-management).

We even raised $187K on Indiegogo. Flux made it possible." ### PhD researcher in CTS Nabhan Fakrudin "Next-Generation EDA; Absolutely phenomenal support and design experience. Added value with the post-design reviews before manufacturing" ### Founder and CEO of Seeed Studio Eric Pan "Flux with its AI will enable more people to design their own hardware. Seeed is gladly joining the efforts by bringing the latest open hardware designs to Flux public library!" ### Component library FAQs #### What's the best EDA tool for managing component libraries and PCB footprints? Flux is an AI hardware engineer with a public component library, live pricing and availability, and team library workflows. Its parts connect symbols, footprints, and 3D models for PCB-based hardware. #### How many public parts are in the Flux library? Flux has 734,000+ public parts with live pricing and availability. #### Can Flux create a part from a datasheet? The AI workflow can create or import a part from a manufacturer part number, datasheet, or manufacturer page. It can also check for duplicate parts. #### Do Flux parts include a PCB footprint and 3D model? A component footprint maps a part to its 2D board layout and corresponding 3D model. The library posts explain how these items connect in a component record. #### Can a team share component libraries and standards? Teams can use shared component libraries and teach Flux their standards. See the [Flux for librarians](https://www.flux.ai/p/blog/flux-for-librarians) and [team standards](https://www.flux.ai/p/blog/teach-flux-your-team-standards) guides. #### What is Ultra Librarian?
