• Chipset: ESP8266
• Operating Voltage: 3.0V to 3.6V (Typically 3.3V)
• Flash Memory: 1MB (8Mb)
• Wi-Fi Modes: Station (STA), Access Point (AP), and both (STA+AP)
• Operating Frequency: 2.4GHz
• Power Consumption:
  • Standby: <1mA
  • Transmitting: ~200mA
• Dimensions: Approx. 25mm x 15mm

Applications:

• Home automation (e.g., smart lights, switches, and appliances)
• IoT devices (sensors, actuators, and controllers)
• Wireless data transmission and logging
• Remote monitoring and control systems
• Basic web server hosting

The ESP-01 is an ideal solution for integrating Wi-Fi capabilities into small-scale projects. While basic, it is versatile and widely supported by Arduino, NodeMCU, and other platforms, enabling rapid prototyping and development.
