The ESP32 by Espressif Systems is currently the smallest microcontroller series in the world, featuring built-in WiFi and Bluetooth simultaneously, making it ideal for IoT projects or small electronic applications.
When comparing the ESP32 to the Arduino, Atmel, or PIC, you'll find that the ESP32 offers more pins, a faster processor, and superior overall performance. Some even compare the Raspberry Pi to the ESP32, but the ESP32 is smaller, cheaper, consumes less power, and is more suitable for compact projects.

The ESP32 Dev Board V1 features a positive voltage regulator, specifically the AMS1117-3.3, which enables operation with external power sources. This configuration eliminates the need to keep the board connected to your computer for power. When powered via the VIN pin, the input voltage is passed through the regulator, which then converts it to a stable 3.3V output, providing power to the board’s various power rails.
According to the datasheet, the AMS1117-3.3 can safely operate with input voltages ranging from 4.8V to 12V. However, higher input voltages may necessitate additional heat dissipation to prevent overheating. For optimal performance and thermal management, it is recommended to use an input voltage in the range of 5V to 6V.
For more information on the ESP32 power control system, we invite you to explore our Bengali tutorial titled Powering ESP32 with External Power.
The ESP32 can be programmed using various platforms, such as the Espressif IDE, Thonny IDE, PlatformIO with Visual Studio Code, and the Arduino IDE. A quick search on Google will yield numerous online tutorials covering these platforms. Some notable examples include:
Once you have installed ESP Boards via the Board Manager of Arduino IDE, you can find various example projects, including Blink, Digital Read Serial, Analog Read Serial, Button, PWM, WiFI Web Server, WiFi Web Client, etc.
From the Arduino IDE, go to Tools > Board and select esp32 > ESP32 Dev Module. Once you have the ESP32 board chosen, go to File > Examples. Inside that folder, you will find various example sketches for different functionalities like WiFi, Bluetooth, Sensors, and more.
