Precautions & Usage Tips:

Always use a 3.3V regulated power supply when connecting ESP-01 to avoid damaging the module.
Avoid hot-plugging the ESP-01 into the adapter while it’s powered, as this can short circuit or damage GPIO lines.
Ensure proper orientation of the ESP-01/01S module to avoid reverse connection issues.
When flashing firmware, make sure GPIO0 is pulled LOW and the RST pin is used properly.
Do not connect the VCC pin to 5V; it must be strictly 3.3V for safe operation.
Refer to ESP8266 documentation for hardware-level configurations and safety guides.
