Hi everyone,
I've recently published a detailed comparison article covering four of the most commonly used microcontroller platforms:
Blog link: https://www.bettlink.com/blog/esp32-vs-stm32-vs-rp2040-vs-arduino-guide (https://www.bettlink.com/blog/esp32-vs-stm32-vs-rp2040-vs-arduino-guide)
I would love to hear feedback from the Olimex community—especially from those with hands-on experience using any of these boards for industrial, educational, or hobby projects.
Some questions for discussion:
- Which platform do you personally prefer, and why?
- Have you tested ESP32 or RP2040 in applications typically done with STM32?
- In long-term stability & industrial reliability, how would you compare them?
- What do you think about Arduino-level abstraction vs. bare-metal control?
I welcome any corrections, comparison points, or benchmarks to help improve the guide.
Thanks!
Best regards,
