You can also add other configurations like libraries to be included, upload options, changing the Serial Monitor baud rate and other configurations. Learn how to program the ESP32 and ESP8266 NodeMCU boards using VS Code (Microsoft Visual Studio Code) with PlatformIO IDE extension. We cover how to install the software on Windows, Mac OS X or Ubuntu operating systems. Although it lacks several features, it suffices for the majority of simple DIY IoT projects.
- The best part is that they come with WiFi to communicate with the internet, which sets them apart from other microcontrollers like Arduino.

B) Installing VS Code on Mac OS X (Visual Studio Code)
Additionally, the ESP32’s larger memory makes it more practical for secure connections using TLS. ESP32 devices have more GPIO to work with more useable and complicated projects. It is a better suited for every situation where an application needs a microcontroller.
ESP32 vs ESP8266: Core Differences
Other ESP32-based power management/monitoring boards we have previously covered include the ESP32-S3 PowerFeather board, Olimex ESP32-C3-DevKit-Lipo, and ThingPulse ePulse Feather C6. The NanoCell V2.1 is a development board built around the Espressif ESP32-C3 SoC (system-on-a-chip) preloaded with ESPHome firmware for low-power applications and improved Lithium battery management. The development board is a white printed circuit board with gold-plated contacts and a battery fuel-gauge IC, designed by Frapais’ lab in Greece. 4) Inside the data folder is where you should put the files you want to upload to the ESP32 filesystem. As an example, create a .txt file with some text called test_example.txt (and save it inside the data folder). But this doesn’t mean the ESP32 is a better choice in every case.
Ecosystem and Community Support
3 High-speed main frequency of 240MHz, providing fast performance. If you only need to create a simple IoT project, the ESP8266 is perfectly adequate. In this instance, you don’t need the device powered up and continuously doing WiFi operations. You need that computational power to create the 802.11b/g/n WiFioperation but it is also true that while you need that to communicate toa web page you can design a system that only periodically updates anoutput. For instance you may want to get a temperature reading only oncean hour.

Let’s compare the two modules using the Arduino IDE, which is mostly used to program the ESP32 and ESP8266 microcontrollers. Both boards can be programmed using the Arduino IDE, which is a benefit for individuals who are familiar with the platform. Some libraries are only compatible with the ESP32 or ESP8266 modules, and will not run on both. It is an integrated antenna and RF balun, power amplifier, low-noise amplifiers, filters, and power management module. The entire solution occupies the smallest amount of space on the printed circuit board. This board is used with TSMC 40nm low power technology 2.4 GHz dual-mode Wi-Fi and Bluetooth chips, which have the best power and RF attributes, are safe, dependable, and scalable to a variety of applications.
This means that use-cases that only require a wake-up every minute or longer shoulduse deep-sleep as expected, but use-cases where the microcontroller needs to remain reachable at alltimes work better in the light-sleep mode. The structure of an Arduino program should open with the setup() and loop() functions. The usefulness of AT commands is that the ESP8266 is pre-programmed to run AT commands when sent out of the factory and can be connected straight to a microcontroller’s UART port. From there, a microcontroller can make requests to connect to Wi-Fi, connect to servers, and send or receive data. But AT commands can be complex to work with which is why it is often advised to use a pre-existing library on the microcontroller to handle these commands. In terms of programming, the ESP32 is normally considered to be easier to program than the ESP8266.
Additionally, if you have a syntax error somewhere in your program, it will underline it in red even before compiling. It works with the ESP32 and ESP8266 boards (both have the on-board LED connected to GPIO 2). In this file, you can also include the identifier of libraries you’ll use in your project using the lib_deps directive, as we’ll see later. For you to get an overview on how PlatformIO works on VS code, we’ll show you how to create, save and upload a “Blinking LED” sketch to your ESP32 or ESP8266 board. The ESP32 contains 34 GPIO pins, compared to 16 on the ESP8266. However, the ESP32’s advantages can outweigh the cost for some projects.
In addition, the developer community around both modules is robust and active, with an abundance of online forums, extensive libraries, and tutorials. If you have an Internet of Things project in mind, you’ll inevitably face the choice between these two MCU heavyweights. esp32 vs esp8266 They are small, low-power Wi-Fi-enabled microcontrollers with 32-bit CPUs ideal for controlling a wide range of electronics projects. We’ve got pre-production samples, and Espressif is still working on supporting all the features of the ESP32-C3 in the IDF.
The ESP8266 is less costly than the ESP32, and it can be used with different types of development boards. The ESP8266 is high power-efficient than the ESP32, which can be good for battery-powered projects. When it comes to developing IoT projects and embedded systems, the choice of microcontroller can greatly influence the outcome of your project. Two popular options that often come into consideration are the ESP32 and the ESP8266.
Additionally, it incorporates an energy-efficient architecture and a 32-bit Tensilica processor. While technically the term “ESP32” denotes the chip itself, manufacturers often use it interchangeably to refer to both the modules and development boards that incorporate this chip. 3 Both ESP32 and ESP8266 can be programmed to achieve a variety of functions and support a variety of programming languages and development environments, such as C/C and Arduino. Currently, it is possible to program both boards using the Arduino IDE programming environment. However, they may not be compatible with the same libraries and commands, and some libraries are only compatible with one of the boards, so some modifications are required.
In the end, your selection of a microcontroller will depend more on your project’s specific requirements than hard numbers. ESP32 clearly wins most match ups, but it falls behind in simplicity and power efficiency. This explains why the ESP8266 remains a popular choice for many, despite not being the top performer. However, the price difference between the two has been reduced in recent years.
The ESP32, unlike the ESP8266, also features integrated Bluetooth v4.2 which increases its connectivity options and supports Bluetooth low-energy (BLE) mode. Also integrated into the ESP32 is hardware security in the form of cryptographic acceleration, flash encryption, and secure boot making the ESP32 a secure platform for IoT project prototyping. The ESP32 and ESP8266 processors are powerful options for Arduinoprojects, offering built-in WiFi connectivity and compatibility with theArduino IDE.
The ESP8266 is a system on a chip that combines a WiFi module with an IP/TCP protocol stack (SOC). The ESP8266 gives you access to any microcontroller via your WiFi connection. The ESP8266’s ability to host an application or offload all WiFi networking tasks is one of its most crucial characteristics. Even under the most demanding industrial situations, it can function dependably because of its exceptional sturdiness. The ESP8266 consumes less power in deep-sleep mode with periodic wake-up when using an open access point. However, when using a secure access point or in light-sleep mode maintaining an association, the ESP32 performs better in terms of power consumption.
It provides you with a faster processor and good memory size, which allow considerable larger projects to be designed on only one SOC. It features a buck-boost converter that reduces standby current consumption to 66uA (excluding https://traderoom.info/ the current consumed by the ESP32 module). The battery management system (BMS) integrated circuit supports accurate capacity measurement and protects connected Lithium batteries from overcharging and other harmful scenarios.
