ESP32 vs Arduino vs Raspberry Pi Boards: Pros and Cons

blog 100

In this blog, we'll delve into the features, capabilities, and potential applications of the ESP32, Arduino, and Raspberry Pi boards, comparing and contrasting these three platforms, exploring their respective strengths and weaknesses.

What is ESP32?



The ESP32 is a powerful microcontroller developed by Espressif Systems. It is appropriate for a variety of Internet of Things applications due to its dual-core processor, integrated Wi-Fi and Bluetooth connection, and extensive peripheral connectors. The ESP32 is a popular choice for battery-powered applications because of its high level of integration and low power consumption.


Who Invented ESP32?

Espressif Systems, a Shanghai, China-based semiconductor business, designed the ESP32. One of Espressif Systems' major products is the ESP32. The company is well-known for its emphasis on wireless connectivity and Internet of Things solutions.


How Long Will ESP32 Last on Battery?

An ESP32-based project's battery life is influenced by several variables, including the peripherals' power consumption, the battery's capacity, and the use of sleep modes. An ESP32 is ideally suited for portable and battery-powered applications since it can operate for extended periods on a single battery charge with careful power management and the use of low-power sleep modes.


What is Arduino?


Arduino is an open-source electronics platform built on user-friendly hardware and software. It is made up of a physical programmable circuit board, also known as a microcontroller, and a development environment used to write, compile, and upload code to the board. An extensive range of switches and sensors can be utilized to create interactive objects or settings, and an Arduino board can be used to control various lights, motors, and other physical outputs.


Who Invented Arduino?

Massimo Banzi, David Cuartielles, Tom Igoe, Gianluca Martino, and David Mellis were the developers who designed Arduino. In Ivrea, Italy, at the Interaction Design Institute Ivrea (IDII), the project got its start.


Can Arduino Store Data?

There isn't much storage on Arduino boards; the program code is usually stored in flash memory. On the other hand, data gathered by the Arduino can be stored on external storage devices like SD cards or EEPROM (Electrically Erasable Programmable Read-Only Memory).


What’s Raspberry Pi?

Raspberry Pi


The Raspberry Pi is a series of small single-board computers developed by the Raspberry Pi Foundation in the United Kingdom. These computers can handle a lot of tasks that a desktop computer can, including word processing, spreadsheets, internet browsing, and gaming. They can also be used for electrical projects.


Can Raspberry Pi Run Windows?

Yes, the Raspberry Pi is capable of running Windows 10 IoT Core. This Raspberry Pi version of Windows is appropriate for the Internet of Things and embedded applications because it is made for small, inexpensive devices.

How ESP32 Works?

The code that the ESP32 runs is kept in its flash memory. Numerous functions, including reading sensor data, operating actuators, and facilitating Bluetooth or Wi-Fi communication, can be written into it. Multitasking is made possible by the dual-core processor, and connecting a wide range of sensors and devices is made flexible by the abundance of peripheral interfaces.


How to Program ESP32?

The ESP32 core can be used to program the ESP32 using the Arduino IDE. Additionally, a collection of tools and libraries for creating applications for the ESP32 are offered by the ESP-IDF (Espressif IoT Development Framework). The C or C++ programming languages can be used.


How Arduino Works?

To operate, an Arduino microcontroller must have a program uploaded to it. The program can communicate with different sensors, actuators, and other electrical parts that are attached to the Arduino board. Write, compile, and upload code to the board with ease using the intuitive interface offered by the Arduino IDE.


How Arduino is Programmed?

Based on the Processing programming environment, Arduino is programmed using the Arduino IDE. A condensed version of the C++ programming language can be used with the IDE to write and upload programs to the Arduino board. Compiling and uploading the code to the board using USB is how it is accomplished.


How Raspberry Pi Works?

The Raspberry Pi functions as a full-fledged computer and can run several operating systems, including Windows 10 IoT Core, Ubuntu, and Raspbian. It has numerous uses, including word processing, media playing, programming, online browsing, and many more. The Raspberry Pi is appropriate for embedded and Internet of Things projects because of its GPIO ports, which enable it to interface with external electronic components.

ESP32 vs Arduino vs Raspberry Pi Boards


  • Ideal for: wearable technology, Internet of Things projects, and battery-operated projects requiring Bluetooth and Wi-Fi access.
  • Pros: Less costly, low power consumption, integrated Wi-Fi and Bluetooth, more powerful than Arduino.
  • Cons: Less user-friendly than Arduino, with a smaller community and fewer resources accessible; larger projects may require more coding expertise.


  • Ideal for: Easy tasks that don't need a lot of connectivity or computing power.
  • Pros: Quite affordable, a sizable community, an abundance of resources, ease of use, beginner-friendliness.
  • Cons: Not as powerful as the Raspberry Pi and ESP32, has fewer built-in connectivity options (often no Bluetooth or Wi-Fi), and is not the best choice for intricate applications.

Raspberry Pi:

  • Ideal for: Multimedia apps, operating systems with extensive processing power requirements, and complex projects.
  • Pros: Most potent of the three, runs Linux, is capable of handling challenging activities like online browsing and video playing, and offers a wide range of expansion options.
  • Cons: The priciest of the three, bigger, and power-hungry; more setup and configuration needed; not suitable for straightforward projects.



In conclusion, each of the three platforms—the ESP32, Arduino, and Raspberry Pi—is adaptable and has advantages and uses of its own. The Raspberry Pi functions as a full-fledged computer for a variety of purposes, Arduino is ideal for interactive and embedded projects, and the ESP32 is great for the Internet of Things and low-power applications.
