ESP32 vs ESP8266: Choose the Right Wi-Fi Microcontroller
5 Programming can be done using the Arduino development environment, supporting open-source projects and enabling fast development. However, the ESP8266 and ESP32, as microcontroller chips specifically designed for wireless connectivity, have built-in WiFi and Bluetooth functionality and offer lower power consumption and cost. For projects that focus on wireless communication and energy efficiency, the ESP8266 and ESP32 may be more suitable for their needs. With excellent performance and rich functionality, the chip provides reliable support for the connection and data transmission of IoT devices.
ESP8266 vs ESP32: GPIO-Pins
The ESP32 supports Bluetooth communication protocol by default, while the ESP8266 doesn’t. Moreover, the ESP32 contains 10 capacitive sensing GPIOs, that detect touch and can be used to trigger events, or wake-up the ESP32 from deep sleep, for example. You can set PWM signals in any GPIO with configurable frequencies and duty cycle set on the code. For means of comparison, here’s the pinout diagram for the ESP8266 ESP-12E NodeMCU Kit.
So, if you’re building a simple IoT project, the ESP8266 might do the trick for a lower price. However, as time goes by, the ESP32 is being widely adopted, and these differences in terms of development and libraries won’t be noticeable. The ESP32 is a dual-core 160MHz to 240MHz CPU, whereas the ESP8266 is a single-core processor that runs at 80MHz.
The ESP8266 is a complete or self-contained system on a chip (SOC) circuit, Wifi module with IP/TCP protocol stack. The ESP8266 gives access to any microcontroller through your Wifi connection. The ESP8266 is a low-cost Wi-Fi microchip with a built-in TCP/IP stack and microcontroller capability, released in 2014 by Espressif Systems in Shanghai, China. 3 High-speed main frequency of 240MHz, providing fast performance. ESP32 has a larger memory capacity, which allows ESP32 to handle more complex applications and larger amounts of data.
- Many people think that ESP32 is more difficult to handle than ESP8266 because it is more complicated, but in fact ESP32 programming is as easy as ESP8266, especially Arduino language or MicroPython.
- Understanding the peripheral interfaces of microcontrollers is crucial when comparing them.
- In general, ESP32 has better performance, but ESP32 is more expensive than ESP8266.
- First of all, ESP32 and ESP8266 are both very cost-effective Wi-Fi module chips, which are very suitable for projects in the field of the Internet of Things (IoT).

The best part is that they come with WiFi to communicate with the internet, which sets them apart from other microcontrollers like Arduino. This means that you can easily control and monitor devices remotely via WiFi technology or Bluetooth technology (ESP32) at a very low price. The ESP32 is much more powerful than the ESP8266, comes with more GPIOs with multiple functions, faster Wi-Fi, and supports Bluetooth. However, many people think that the ESP32 is more difficult to deal with than the ESP8266 because it is more complex.
What is the difference between ESP32 and ESP8266 chips? Which one has better performance?
Many ESP32 development boards come with small cameras and it is said to be a very capable board. In summary, for simple, low-power Wi-Fi-based projects, the ESP8266 is the preferred choice. On the other hand, if you need more processing power, extra memory, and features like Bluetooth, the ESP32 is the clear winner.
Additionally, both microcontrollers support programming in MicroPython, Lua, JavaScript, and other languages (a comprehensive list is available on their wiki). The developer community for both boards is large and active, offering plenty https://traderoom.info/brainwagon-the-esp32-vs-the-esp8266/ of online forums, extensive libraries, and tutorials. For simpler, battery-powered projects requiring minimal power, the ESP8266 is more suitable due to its lower power consumption in active mode.
We will add here the presence of additional RAM data, which allows you to run the microPython programming language on the controller. This chip is convenient to use in conjunction with the ESP32 development module, which makes it easy to create rapid prototypes since you do not need to design your own PCB. ESP 8285 with almost the same price provides more resources and performance, compared with ESP8266.
If you need higher processing power, more GPIO pins, larger memory resources, and a better energy-efficient design, the ESP32 may be a better choice. Both development boards have their own application space, according to the needs of the project to choose the more cost-effective can be. 1 Dual-core processor capable of multi-threaded real-time processing.2 High-speed main frequency of 240MHz, providing fast performance. 4 Built-in Bluetooth and WiFi functionality, eliminating the need to purchase additional modules and reducing costs.
