Circaflex 540

Customize your testing needs

Circaflex 540 is a modular embedded control system for designing smaller, low-cost, and highly flexible prototypes and products. Select ten modules from a growing library of Circaflex expansion modules and this system is uniquely yours. Rather than working with preselected I/O, you choose from standard signals like analog, digital and TTL I/O, or more application-specific modules like SSRs, reed relays, RTDs, and stepper drivers. After prototyping and choosing the modules for your project, Cyth will convert your modules to a custom board at no charge. Design your own system with Circaflex 540 and achieve the volume, size, and cost needs for your product.
