However, it’s crucial to note that while the Arduino operates on 5V logic, the ESP32 and ESP8266 operate at 3.3V. Both ESP32 and ESP8266 are cheap WiFi-based SOC (Systems on Chip) perfectly suited for DIY projects in the Internet of Things. Both have 32-bit processors, ESP32 is dual-core 80Mhz to 240MHz CPU and ESP8266 is an 80MHz single-core processor.
- In general, ESP32 has better performance, but ESP32 is more expensive than ESP8266.
- These are good news, especially for those used to program the Arduino board and are familiar with the Arduino “programming language”.
- The ESP32 is much more powerful than the ESP8266, comes with more GPIOs with multiple functions, faster Wi-Fi, and supports Bluetooth.
- ESP32 is more powerful than ESP8266, contains more GPIOs with multiple functions, faster Wi-Fi, and also supports Bluetooth.
- There’s abig problem in that when a 32bit processor is operating at160/80MHz (240/160MHz for the ESP32) then power consumption willbe through the roof.
For example, regardless of the board, usually GPIO5 is always the VSPI CS0 pin, GPIO 23 always corresponds to VSPI MOSI for SPI communication, etc. It boasts a dual-core Tensilica Xtensa LX6 microprocessor that can run at up to 240 MHz. It includes 520 KB of SRAM and supports external flash memory of up to 16 MB. It is apparent that both the ESP32 and ESP8266 serve as remarkable toolkits. Preferences may sway towards one or the other based on specific considerations. The ESP8266 exhibits lower current consumption in comparison to its counterpart, while the latter boasts a higher number of digital pins.
People have many doubts regarding which board to use and what is the difference between these, so from this blog, you will be clear about the difference between esp32 and esp8266. There are many programming methods for ESP32 and ESP8266 boards.Currently, two boards can be programmed using the Arduino IDE programming environment. However, they may not be compatible with the same libraries and commands. Some libraries are only compatible with one of the boards, so some modifications are required.
Nevertheless, over time, these issues are expected to be addressed, allowing both boards to excel in their respective applications. Let’s conduct a comparison between the two modules using the Arduino IDE, a widely utilized platform for programming ESP32 and ESP8266 microcontrollers. Both boards are compatible with the Arduino IDE, offering convenience for users familiar with the platform. However, it’s essential to note that certain libraries may exclusively support either the ESP32 or ESP8266, requiring minor adjustments.
These modules come with GPIOs that support various protocols like SPI, I2C, UART, ADC, DAC, and PWM. 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. However, the ESP32 comes at a higher cost, making the ESP8266 more economical for simpler IoT projects. Additionally, as a newer model, the ESP32 may face challenges due to incomplete software optimization, resulting in fewer support resources and potential bugs.

If you don’t set them on the code, the pins will be configured by default as shown in the figure below (the pin location can change depending on the manufacturer). Additionally, there are pins with specific features that make them suitable or not for a particular project. With the ESP32 you can decide which pins are UART, I2C, or SPI – you just need to set that on the code. This is possible due to the ESP32 chip’s multiplexing feature that allows to assign multiple functions to the same pin. In this article, we’ll be using the ESP32 DEVKIT DOIT board as a reference. The information on this page is also compatible with other ESP32 development boards.

While both boards are cost-effective, the ESP32 is slightly pricier. The ESP32 typically ranges from $6 to $12, while the ESP8266 can be found in the $4 to $6 range (actual costs may vary based on the source and specific model). A notable difference with the ESP32 is its Bluetooth capability that allows the ESP32 to not only be limited to Wi-Fi communication, allowing it to be integrated into more projects.
Getting Started with the ESP32 Development Board
- The Reset button, labeled RST and placed in the upper left corner, is used to reset the ESP8266 chip.
- This is possible due to the ESP32 chip’s multiplexing feature that allows you to assign multiple functions to the same pin.
- Both have 32-bit processors, ESP32 is dual-core 80Mhz to 240MHz CPU and ESP8266 is an 80MHz single-core processor.
- However, the “ESP32” term is also used to refer to ESP32 development boards.
- Another popular way of programming the ESP32 and ESP8266 boards is using MicroPython firmware.
- ESP32 is a series of low-cost chip microcontroller power systems.
It quickly https://traderoom.info/brainwagon-the-esp32-vs-the-esp8266/ gained popularity due to its simplicity and low cost. It operates on a Tensilica Xtensa LX3 processor and is primarily intended for smart devices, wearables, and Wi-Fi-enabled projects. In this article, we’ll compare the two popular microcontrollers to help you choose the right one for your project. The Reset button, labeled RST and placed in the upper left corner, is used to reset the ESP8266 chip.
Devices can be controlled and monitored via Wi-fi or Bluetooth at a fraction of the price. Furthermore, the ESP32 has Bluetooth v4.2 BR/EDR and BLE (Bluetooth Low Energy) capabilities, which the ESP8266 lacks. This makes the ESP32 more versatile for wireless communication.

Processing Power and Memory
If you don’t see the COM Port in your Arduino IDE, you probably need to install the USB-to-UART drivers on your computer. Most ESP32 boards use either the CP210x or the CH340 chip depending on the board you’re using. Our preferred method to program the ESP32 is with C/C++ “Arduino programming language”.
