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.
Turn Zephyr into a competitive advantage. RISCstar engineers help embedded product teams deliver connected, secure, and high-performance devices on Arm and RISC-V — on time and built to last.
Let’s Talk

Complexity in Connected, Embedded Real-time Systems

Delivering connected devices on time — while maintaining safety, security, and performance — is one of the hardest challenges in embedded engineering. Product teams face challenges such as:
  • Integrating new silicon and custom board designs quickly and reliably
  • Meeting strict real-time and power constraints across diverse hardware
  • Ensuring product and data security across the full device lifecycle
  • Supporting wireless connectivity standards
  • Controlling long-term maintenance costs and technical debt

Without the right expertise, integration delays and software instability can slow time-to-market and erode product margins. RISCstar provides the Zephyr engineering depth to overcome these challenges and deploy with confidence.

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:
  • Highly configurable — only include what your product needs
  • Open-source innovation backed by an active ecosystem
  • Security-first design including MCUboot secure boot and PSA Certified components
  • Broad connectivity: Bluetooth LE, Wi-Fi, Thread, CAN, Matter, and more
  • Vendor neutrality — supports leading Arm and RISC-V platforms
RISCstar understands Zephyr inside and out — including how to push performance and reliability where it matters most.
