CircuitHub

CircuitHub is an on-demand electronics manufacturing platform that provides rapid, low-cost turnkey PCB (printed circuit board) assembly for hardware and robotics teams. Engineers upload their CAD and BOM files (Altium, EAGLE, KiCAD) to an automated web application that reconciles the bill of materials against 35,000+ stocked common parts, generates an instant quote, previews a virtual build, and manufactures small prototype-to-production batches in the USA — with 81% of full turnkey orders shipping within three days and real-time quality metrics for transparency. CircuitHub has delivered over 1.5 million boards and placed 87 million parts for more than 20,000 engineers. The company operates a web application rather than a public developer API; user authentication is handled through an Auth0-hosted OpenID Connect tenant.

CircuitHub is profiled on the APIs.io network. Tagged areas include Company, Electronics Manufacturing, PCB Assembly, Hardware, and Robotics.

CircuitHub’s developer surface includes engineering blog, pricing, signup flow, authentication, and 9 more developer resources.
