Detailed Description
The ESP8266 ESP-01 is one of the earliest and most widely used Wi-Fi modules in the ESP8266 family. Its small size and affordability make it an excellent choice for projects that require basic wireless connectivity without many input/output pins.
The module integrates a full TCP/IP stack, allowing it to connect directly to the internet and communicate with cloud servers or local networks. It can be used as a standalone microcontroller for simple applications or as a Wi-Fi adapter controlled by another microcontroller such as an Arduino.
Due to its limited number of GPIO pins, the ESP-01 is best suited for straightforward IoT tasks such as wireless switching, remote control, and data transmission. Programming can be done using AT command firmware or custom firmware through the Arduino IDE with the help of an external USB-to-TTL converter.

Important Note
The ESP8266 ESP-01 operates at 3.3V only and is not 5V tolerant. A stable 3.3V power supply is required, as insufficient current can cause connection issues. Programming requires an external USB-to-TTL converter, and GPIO availability is limited.
