STM32 vs Arduino

Arduino is a prototyping ecosystem (8-bit AVR or ARM MCUs). STM32 is an industrial MCU family developed with STM32CubeIDE, Keil, or IAR. Arduino targets 10-100 unit prototypes. STM32 targets 1,000-100,000+ unit production. Arduino starts with a pre-wired board; STM32 starts with a custom schematic.

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

Use Arduino libraries on STM32?

Yes via STM32duino core. For production use HAL/LL for better performance. Prototype with Arduino, rewrite for production.

Arduino for commercial use?

Great for proof-of-concept. For production, design a custom PCB. Arduino boards’ cost and certification issues make them uneconomical at scale.
