However, you should take into account that whereas the Arduino works with 5V logic, the ESP32 and ESP8266 work at 3.3V. This means that you can easily control and monitor devices remotely via Wi-Fi or Bluetooth (in the case of ESP32) for a very low price.Īlternatively, if you don’t need to use its wireless capabilities, you can use the ESP32/ESP8266 to control inputs and outputs as you would do with an Arduino. The best part is that these boards come with wireless networking included, which makes them apart from other microcontrollers like the Arduino. These modules come with GPIOs that support various protocols like SPI, I2C, UART, ADC, DAC, and PWM. ![]() The ESP32 is a dual-core 160MHz to 240MHz CPU, whereas the ESP8266 is a single-core processor that runs at 80MHz. ![]() The ESP32 and ESP8266 are cheap Wi-Fi modules perfectly suited for DIY projects in the Internet of Things (IoT) and Home Automation fields.īoth chips have a 32-bit processor. ![]() What’s the difference between ESP32 and ESP8266? Should you use the ESP32 or the ESP8266 in your projects? In this article, we’ll compare the ESP32 with the ESP8266 and cover the pros and cons of each board.
