The pinout of a common ESP8266 WiFi module, such as the ESP-01, can vary slightly between different versions and manufacturers. Below is a typical pinout for the ESP-01 module:

  1. VCC (3.3V): This is the power supply pin for the ESP8266 module. It requires a stable 3.3V power source. Do not connect it to 5V as it can damage the module.
  2. GND (Ground): This is the ground or common reference voltage.
  3. TX (Transmit): This pin is used for serial data transmission from the ESP8266 to an external device like an Arduino. It sends data from the module to another device.
  4. RX (Receive): This pin is used for serial data reception by the ESP8266 from an external device. It receives data from another device.
  5. GPIO0 (General-Purpose Input/Output 0): This pin can be used for general-purpose digital input/output operations. It is often used during the flashing of firmware, so its state during boot-up can affect the module’s behavior.
  6. GPIO2 (General-Purpose Input/Output 2): Similar to GPIO0, this pin can also be used for general-purpose digital input/output operations. It’s commonly used for connecting external components like LEDs or sensors.
  7. CH_PD (Chip Enable): This is the chip enable pin, which is used to enable the ESP8266 module.
  8. RST (Reset): This is the reset pin used to reset the module.
