CircuitNinja

CircuitNinja is an online printed circuit board (PCB) prototype manufacturer. Developers upload Gerber files through a customer account, receive an automatic file check and preview, and the boards are produced at the company's Prague facility with a stated 24-hour turnaround from order approval. Standard options listed include FR4 boards and online order tracking.

Customers are electronics and hardware developers who order single prototypes or small batches, and universities and R&D teams that are directed to a sales team for custom arrangements. Revenue appears to come from per-order PCB manufacturing, with an online price calculator on the website. The company was founded in April 2025 and is registered in Praha 9-Vysočany, Czech Republic, with a listed employee band of 10-19. Its website lists a single Prague production site and a contact address, with a stated focus on local European production as an alternative to overseas sourcing.

The website describes a pilot phase with first customer orders in March 2026, and mentions that the company is developing its own software for PCB checking and design. Multilayer boards (6–12 layers) are marked as in preparation. Contact is available by email and phone, with a stated weekday service window.
