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.
The ESP32 and ESP8266 are cheap Wi-Fi modules perfectly suited for DIY projects in the Internet of Things (IoT) and Home Automation fields.
Both chips have a 32-bit processor. The ESP32 is a dual-core 160MHz to 240MHz CPU, whereas the ESP8266 is a single-core processor that runs at 80MHz.
These modules come with GPIOs that support various protocols like SPI, I2C, UART, ADC, DAC, and PWM. The best part is that these boards come with wireless networking included, which makes them apart from other microcontrollers like the Arduino. 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.
Alternatively, 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. However, you should take into account that whereas the Arduino works with 5V logic, the ESP32 and ESP8266 work at 3.3V.
Both boards are cheap, but the ESP32 costs slightly more. While the ESP32 can cost around $6 to $12, the ESP8266 can cost $4 to $6 (but it really depends on where you get them and what model you’re buying).

ESP32 Development Boards Review and Comparison
Using ESP32 or ESP8266 bare chips is not easy or practical, especially when testing and prototyping. Most of the time, you’ll want to use ESP32 and ESP8266 development boards. These boards come with all the needed circuitry to power the chip, connect it to your computer, a circuit to upload code easily, pins to connect peripherals, built-in power and control LEDs, and other useful features.
The ESP32 and ESP8266 development boards we use more often are the ESP32 DEVKIT DOIT Development board and the ESP8266 ESP-12E NodeMCU Kit and these are the ones we recommend for beginners. However, there are many other models of development boards that you can choose from. We recommend that you read the following guides:
The ESP32 has more GPIOs than the ESP8266, and you can decide which pins are UART, I2C, SPI—you need to set that on the code. This is possible due to the ESP32 chip’s multiplexing feature that allows you to assign multiple functions to the same pin.
If you don’t set them on the code, they will be on the pins defined by default, as shown in the following figure (this is an example for the ESP32 DEVKIT V1 DOIT board (version with 36 GPIOS)—the pin location can change depending on the manufacturer).
To learn more about the ESP32 GPIOs and how to use them, read:
You can set PWM signals in any GPIO with configurable frequencies and duty cycle set on the code.
When it comes to the analog pins, these are static, but the ESP32 supports measurements on 18 channels (analog-enabled pins) versus just one 10-bit ADC pin on the ESP8266. The ESP32 also supports two 8-bit DAC channels.
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.
There are many ways to program the ESP32 and ESP8266 boards. Both boards can be programmed with the Arduino core using the Arduino IDE or other IDEs (like VS Code with the PlatformIO extension).
These are good news, especially for those used to program the Arduino board and are familiar with the Arduino “programming language”.
Getting started with the ESP32 or ESP8266 using Arduino IDE and have your first project running is very simple. You can follow these guides:
Although you can program both boards using Arduino IDE, they might not be compatible with the same libraries and functions. Some libraries are just compatible with one of the boards. This means that most of the time, your ESP8266 code will not be compatible with the ESP32. However, usually, you need to make a few modifications.
We have a dedicated list of free tutorials and projects for the ESP32 and ESP8266 boards using the Arduino IDE that you might found useful:
Another popular way of programming the ESP32 and ESP8266 boards is using MicroPython firmware.
MicroPython is a re-implementation of Python 3 targeted for microcontrollers and embedded systems. MicroPython is very similar with regular Python. So, if you already know how to program in Python, you also know how to program in MicroPython.
In MicroPython, most Python scripts are compatible with both boards (unlike when using Arduino IDE). This means that most of the time, you can use the same script for ESP32 and ESP8266.
You can get started with MicroPython firmware on the ESP32 and ESP8266 very quickly by following our free guides:
So, at this point you may be wondering: Should I get an ESP8266 or an ESP32?
It really depends on what you want to do. There is space for both boards, and both have pros and cons.
The ESP8266 is cheaper than the ESP32. Although it doesn’t have as many functionalities, it works just fine for most simple DIY IoT projects. However, it has some limitations in the GPIO mapping, and it might not have enough pins for what you intend to do. If that’s the case, you should get an ESP32.
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. On the contrary, in our opinion, it is as easy to program the ESP32 as the ESP8266, especially if you intend to program it using the “Arduino language” or MicroPython.
The ESP32 has some cons too. The ESP32 is more expensive than the ESP8266. So, if you’re building a simple IoT project, the ESP8266 might do the trick for a lower price. Additionally, because the ESP8266 is “older” than the ESP32, some libraries and features are better developed for the ESP8266, and you’ll find more resources (forums, people with the same issues, and how to solve them, etc.). However, as time goes by, the ESP32 is being widely adopted, and these differences in terms of development and libraries won’t be noticeable.
My personal experience: in 2021, I use almost exclusively the ESP32 for IoT projects. It is more versatile, and it comes with much more functionalities like Bluetooth, different wake-up sources, many peripherals, and much more. Additionally, the price difference is not a big deal, in my opinion. Once you move to the ESP32, you won’t want to go back to the ESP8266.

Error: “Brownout detector was triggered” When you open your Arduino IDE Serial monitor and the error message “Brownout detector was triggered” is constantly being printed over and over again. It means that there’s some sort of hardware problem.
It’s often related to one of the following issues:
Poor quality USB cable; USB cable is too long; Board with some defect (bad solder joints); Bad computer USB port; Or not enough power provided by the computer USB port. Solution: try a different shorter USB cable (with data wires), try a different computer USB port or use a USB hub with an external power supply.
