Firmware Development Cost Guide

Firmware cost depends on MCU, protocol stacks, RTOS, certification. Simple (one sensor, one protocol): $5,000-15,000. Moderate (multi-protocol, RTOS, OTA): $15,000-40,000. Complex (real-time control loops, safety-critical): $40,000-100,000+. Protocol licensing (CANopen, PROFINET) adds $5,000-30,000.

Key Takeaways

• Real-world engineering considerations from 10+ years of STM32 development
• Practical tradeoffs between performance, cost, and time-to-market
• Direct experience across industrial, energy, and IoT deployments

Frequently Asked Questions

What determines cost most?

MCU complexity, protocol count, RTOS, certification. IEC 61508 adds 20-30% engineering effort.

Save by developing in China?

Chinese rates ($30-60/hr) vs US/EU ($100-200/hr) save 40-60%. Key is thorough technical specs.
