The pinout

  1. VCC, Voltage (+3.3 V; can handle up to 3.6 V): no 5V, please!!
  2. GND, Ground (0 V)
  3. RX, to Receive data
  4. TX, to Transmit data
  5. CH_PD, Chip power-down
  6. RST, to Reset the ESP8266
  7. GPIO 0, General-purpose input/output No. 0
  8. GPIO 2, General-purpose input/output No. 2
The ESP8266 comes with default firmware and allow you to communicate using standard “AT commands”. While powering up the circuit red LED onboard will light up and while uploading the code or transception the blue LED will flash during the process.
