FAQ
Is ESP32 good for FYP projects?
Yes. ESP32 is one of the best boards for IoT FYP projects because it includes WiFi, many GPIO pins and strong Arduino IDE support.
Can ESP32 use 5V sensors?
Many modules accept 5V power, but ESP32 GPIO pins are 3.3V only. Use level shifting or a divider when a signal can output 5V.
