If you have an Internet of Things project in mind, you’ll inevitably face the choice between these two MCU heavyweights. They are small, low-power Wi-Fi-enabled microcontrollers with 32-bit CPUs ideal for controlling a wide range of electronics projects. 1 Both WiFi modules come with GPIOs and support various protocols such as SPI, I2C, UART and more.

In addition, the developer community around both modules is robust and active, with an abundance of online forums, extensive libraries, and tutorials. Due to its lower power consumption in active mode, the ESP8266 is better suited for simple, low-power projects powered by a battery pack. 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.

The ESP8266 features a 32-bit Tensilica Xtensa L106 single-core processor, running at 80 MHz, which can be overclocked to 160 MHz. It comes with 32 KB of instruction RAM, 80 KB of user-data RAM, and external QSPI flash – 512 KB to 4 MB. 2 Built-in Bluetooth and WiFi functionality, eliminating the need to purchase additional modules and reducing costs. The ESP32 is more powerful than the ESP8266, includes more GPIOs with multiple functions, faster Wi-Fi, and also supports Bluetooth.

• Compared to the ESP8266 and ESP32, these development boards may offer more features and flexibility in terms of computing power, storage capacity, peripheral interfaces and software ecosystem.
• Depending on where you’re buying from, you can generally find both boards for sale at more or less the same price.
• This is only because of its broad range of the operating temperature.

ESP32 vs ESP8266 – Which One To Choose?

At this time, you can choose to use ESP32 or ESP8266 according to the needs of the project. In summary, for straightforward, low-power Wi-Fi projects, the ESP8266 is the better option. If your project requires more processing power, additional memory, and features like Bluetooth, the ESP32 is the superior choice. Launched in 2016, the ESP32 is the successor to the ESP8266, offering numerous enhancements. These improvements include a faster processor, upgraded Wi-Fi, Bluetooth connectivity, additional GPIO pins, and other features.

Factors like processing power, connectivity options, hardware features, development environments, and pricing will be considered. When planning an Internet of Things (IoT) project, choosing between these two popular microcontrollers is a common dilemma. Both the ESP32 and ESP8266 are renowned for their compact size, low power consumption, and built-in Wi-Fi capabilities, making them excellent choices for a variety of electronics projects. Now, the following table summarizes the key characteristics of these three Espressif microcontrollers. Comparing esp32 vs esp8266 power consumption, esp8266 has a better value during standard work mode, and esp32 has very low power consumption in the sleep mode.

The ESP32, which was introduced in 2016, is the successor to the ESP8266 and offers several improvements over it. These include a faster processor, faster Wi-Fi, Bluetooth connectivity, more GPIO pins, and several other features. More importantly, it features a dual-core Tensilica Xtensa LX6 microprocessor, which significantly enhances its computational capabilities. Let’s begin with a comparison of the two to help you make a decision. We won’t focus solely on the fastest MCU, the most power-efficient one, or the one offering the best value for money. Instead, we’ll consider various factors, including processing power, connectivity features, hardware specifications, development environments, pricing, and more.

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. The prices of both chips are very cheap, but the cost of ESP32 is slightly higher. In addition, due to the long time to market of ESP8266, more support can be obtained in terms of software, which will be more convenient and compatible to use. However, ESP8266 has some limitations in GPIO mapping, and there are not enough pins to operate.

ESP32 vs ESP8266: Funk

The ESP32, with its additional features and capabilities, comes at a slightly higher cost, justified by its increased processing power and versatility. When comparing two microcontrollers, it’s important to know what types of peripheral interfaces they have. These interfaces are the primary means by which the microcontrollers communicate with sensors and other devices, and they have a big impact on the complexity and type of projects that you can build.

On the contrary, in our opinion, it is as easy to program the ESP32 as the ESP8266, especially if you intend to program it https://traderoom.info/brainwagon-the-esp32-vs-the-esp8266/ using the “Arduino language” or MicroPython. In general, ESP32 has better performance, but ESP32 is more expensive than ESP8266. If you only need to make a simple IOT project, then ESP8266 is completely sufficient. Both development boards have their own application space, and the one with a higher price ratio can be selected according to the needs of the project. ESP32 is more powerful than ESP8266, contains more GPIOs with multiple functions, faster Wi-Fi, and also supports Bluetooth.

It features 520 KB of SRAM and supports up to 16 MB of external flash memory. The ESP8266 is equipped with a 32-bit Tensilica Xtensa L106 single-core processor running at 80 MHz, which can be overclocked to 160 MHz. It includes 32 KB of instruction RAM, 80 KB of user-data RAM, and external QSPI flash memory ranging from 512 KB to 4 MB.

What Are the Best Applications for IoT in the New World of IC Power Management?

It adds an extra CPU core, faster Wi-Fi, more GPIOs, and supports Bluetooth 4.2 and Bluetooth low energy. ESP32 has more GPIOs than ESP8266, and the code can be set according to different pins (UART, I2C, SPI), because the multiplexing function of the ESP32 chip allows you to assign multiple functions to the same pin. The ESP32 offers enhanced performance with its dual-core Tensilica Xtensa LX6 microprocessor, capable of running at up to 240 MHz.

All these possibilities of using the Arduino IDE gave momentum to the proliferation of ESP microcontrollers in various models. Add Wi-Fi, Bluetooth (for the ESP32), and low-power consumption, and we have the bestseller among microcontrollers. Microcontroller programming is usually done in assembler or C, although there are compilers for other languages, such as microPython or Lua. A key feature of the module is the ability to connect an external antenna through the U.FL connector.
