Difference between esp32 and node mcu in simple words? General Discussion
This provides enough speed for any application that requires a microcontroller with connectivity. The nodemcu ESP32 is a series of low-cost, low-power microcontrollers with built-in ESP32 Wi-Fi and dual-mode Bluetooth. The ESP32 is designed for low-power Internet of Things applications. It adds an extra CPU core, faster Wi-Fi, more GPIOs, and supports Bluetooth 4.2 and Bluetooth low energy.
The ESP32 serves as the successor to the ESP8266, introducing an additional CPU core, faster Wi-Fi, expanded GPIOs, and support for Bluetooth 4.2 and Bluetooth Low Energy. The ESP32 chip adds additional CPU cores, faster WiFi transmission technology and more GPIOs, and supports Bluetooth 4.2 protocol and Bluetooth Low Energy. In addition, the ESP32 chip is equipped with touch-sensitive pins, which can be used to wake up ESP32 to deep sleep, a built-in hall-effect sensor and a built-in temperature sensor.
The ESP32 also has far moreSRAM than the ESP8266; actually four times the ESP8266 SRAM. Expensive device, I would only be looking at that if you really need it’s features such as range and robustness to weather. Otherwise you can build a wifi device from an esp for under 10% of that cost.
How to Choose an ESP32 Development Board?
In MicroPython, most Python scripts are compatible with both boards (different from when using the Arduino IDE), ESP32 and ESP8266 can use the same script. The ESP32 is a dual-core 160MHz to 240MHz CPU, whereas the ESP8266 is a single-core processor that runs at 80MHz. Both microcontrollers provide low power operation options byperiodically waking the processor to transmit data over WiFi.
- 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 microcontrollers provide low power operation options byperiodically waking the processor to transmit data over WiFi.
- In this article, we’ll compare the ESP32 with the ESP8266 and cover the pros and cons of each board.
- The ESP-32 board has 48 general purpose input/output pins from which only 25 are available as pin headers on both sides of the ESP-32 board.
- The regulator’s output is also broken out to one of the board’s sides and labeled as 3V3.
It comes with 32 KB of instruction RAM, 80 KB of user-data RAM, and external QSPI flash – 512 KB to 4 MB. 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. Moreover, the ESP32 proves to be a reliable board, despite occasional flakiness in its firmware and connected peripherals.
1. Core System: ESP32 and ESP8266
The ESP32 and ESP8266 are cheap Wi-Fi modules perfectly suited for DIY projects in the Internet of Things (IoT) and Home Automation fields. It’s a good practice to periodically ensure you have the latest version of the ESP32 boards installed. In Arduino IDE 2, you’ll receive a pop-up notification prompting you to update whenever a new version becomes available. Wait a few seconds while the code compiles and uploads to your board.
- Both WiFi modules come with GPIO and support various protocols such as SPI, I2C, and UART.
- So, in terms of programming support and community resources, there is little to no competition between the two boards; both provide an extensive range of supported languages and resources.
- It comes with 32 KB of instruction RAM, 80 KB of user-data RAM, and external QSPI flash – 512 KB to 4 MB.
- When the ESP8266 draws up to 80mA during RF transmissions, it can reliably supply up to 600mA, which should be more than enough.
- That allows you to do some fancy stuffemulating an SD card within the flash memory itself.
The ESP32 has a 32-bit processor with an ultra-low-power coprocessor and multiple https://traderoom.info/brainwagon-the-esp32-vs-the-esp8266/ input/output connectors, including digital-to-analog converters. ESP32 provides a secure platform for the Internet of Things. ESP32 is an upgraded version of ESP8266, it has 34 GPIO pins and comes with Xtensa dual-core processor 160MHZ. But this doesn’t mean the ESP32 is a better choice in every case. In the end, your selection of a microcontroller will depend more on your project’s specific requirements than hard numbers.
However, ESP8266 has some limitations in GPIO mapping, and there are not enough pins to operate. At this time, you can choose to use ESP32 or ESP8266 according to the needs of the project. I think we’ve included all the required information for you to get started. You learned what is an ESP32, how to choose an ESP32 development board, and how to upload new code to the ESP32 using Arduino IDE.
thoughts on “Getting Started with the ESP32 Development Board”
If you’re familiar with the ESP8266, the ESP32 is its successor, loaded with lots of new features. ESP32 is a series of low-cost chip microcontroller power systems. The ESP32 series is created and developed by Espressif Systems.
If you have an ESP32 DEVKIT DOIT board, the built-in red LED will turn on. This board also comes with a RESET button (may be labeled EN) to restart the board and a BOOT button to put the board in flashing mode (available to receive code). It comes with a microUSB interface that you can use to connect the board to your computer to upload code or apply power. This particular ESP32 board comes with 36 pins, 18 on each side. I have been working withwireless temperature and humidity sensor. I want your suggestions, which one is better between esp32 or esp8266 to send this sensor data to HA.Any leads will be a great help.Thanx.
ESP32 vs ESP8266: Advantages and Disadvantages
In most of our ESP32 projects, we use the ESP32 DEVKIT DOIT board, and that’s the one we recommend for beginners. There are different versions of this board with a different number of available pins (30, 36, and 38)—all boards work in a similar way. When you create a useful IOT device such as an ESP8266 it willinevitably be used for stand alone battery powered operation. 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. Config in ESPHome is extremely simple and ESPHome supports OTA updates.
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.

To program your boards, you need an IDE to write your code. While it’s not the best IDE, it works well and is simple and intuitive to use for beginners. After getting familiar with Arduino IDE and you start creating more complex projects, you may find it useful to use VS Code with the Platformio extension instead.
The development board equips with an ESP-WROOM-32 module containing Tensilica Xtensa Dual-Core 32-bit LX6 microprocessor. Both WiFi modules come with GPIO and support various protocols such as SPI, I2C, and UART. The best part is that they come with a wireless network, which distinguishes them from other microcontrollers such as Arduino. This means that you can easily remotely control and monitor your equipment via WiFi technology or Bluetooth technology (ESP32) at a very low price. 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.
