ESP32 Pin Description

ESP32 to 8266 Comparison:

  • ESP32 is a powerful device that runs through a 32-bit dual-core processor CPU with a clock speed of 160MHz to 240MHz while ESP8266 is a single-core CPU with a clock speed of around 80MHz. 
  • As we know the ESP32 has a higher speed compared to ESP8266 it consumes more power.
  • ESP32 has more than 16 GPIO pins along with UART, I2C, I2S, ADC, DAC, and TWAI pins. ESP8266 also comes with 16 General Purpose Input Output (GPIO) Pins and other GPIO, UART, I2C, I2S and ADC Pins.
  • ESP32 comes with Bluetooth and WIFI together onboard whereas the ESP8266 comes with only WIFI.
