Zephyr Engineering

Delivering connected devices on time — while maintaining safety, security, and performance — is one of the hardest challenges in embedded engineering. Success depends on the right operating system, optimized for your hardware and backed by proven expertise.
Zephyr RTOS provides a modern, open-source foundation for IoT and embedded devices across Arm and RISC-V platforms. With RISCstar as your engineering partner, you gain a team experienced in hardware enablement, system integration, and production-grade software delivery.
We help you turn Zephyr into a competitive advantage.

The Challenge: Complexity in Connected, Embedded Systems

Product teams face intense pressure to:
Without the right expertise, integration delays and software instability can seriously impact your business — slowing time-to-market and increasing technical debt.

Why Zephyr RTOS?

Zephyr is an open-source, real-time operating system (RTOS) designed for resource constrained IoT devices that require long-term maintainability. Its modular architecture enables manufacturers to scale a single codebase across multiple products and hardware families.
Benefits include:
RISCstar understands Zephyr inside and out — including how to push performance and reliability where it matters most.
