Common Questions
What is the main risk of cheap WiFi MCUs?
The main risk is not the chip alone; it is weak English documentation, immature SDK examples, and inconsistent module pinouts.
Are ESP32 alternatives production-ready?
Some can be, but each alternative needs SDK, supply, module, certification, and library checks before production use.
