ESP32 vs ESP8266 Pros and Cons
These are good news, especially for those used to program the Arduino board and are familiar with the Arduino “programming language”. Both boards can be programmed with the Arduino core using the Arduino IDE or other IDEs (like VS Code with the PlatformIO extension). 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. In this article, we’ll compare the ESP32 with the ESP8266 and cover the pros and cons of each board.
What Are the Best Applications for IoT in the New World of IC Power Management?
ESP8285 has ultra-low power 32-bit MCU with 16-bit RISC core, and WiFi b/g/n/d/e/i/k/r connections. Recently, the use of the updated Wi-Fi module ESP8266, version ESP-01S (based on the ESP8266EX chip with a built-in TCP/IP protocol stack and AT command management), has become very popular. The chip is designed for use in smart outlets, mesh networks, IP cameras, wireless sensors, wearable electronics, and so on. Affordable microcontrollers and convenient firmware development environments also contributed to this widespread use of proprietary IoT development. MicroPython is a re-implementation of Python 3 for microcontrollers and embedded systems. 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.
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. Another way to program the ESP32 and ESP8266 boards is to use the MicroPython firmware.
- Today, in this article we will discuss the two popular microcontrollers.
- We won’t focus solely on the fastest MCU, the most power-efficient one, or the one offering the best value for money.
- ESP microcontrollers are indispensable for prototyping IoT solutions and building fast projects for private use and in small business solutions with a short life cycle.
- The ESP32 development has power, which allows better security and larger RAM for projects, which you cannot run in ESP8266.
Processing Power and Memory
ESP microcontrollers are indispensable for prototyping IoT solutions and building fast projects for private use and in small business solutions with a short life cycle. On the other hand, the rapid proliferation of Espressif microcontrollers has increased not only their cost but also the availability of integration with the popular Arduino IDE development environment. ESP8266 power consumption is comparatively low for such solutions with WiFi. Also, it has a very good option to go into sleep mode, where power consumption is unbelievably low (1.0 mW).
At the same time, note that different manufacturers may vary module parameters, such as pin count and package form-factor. Let’s take a look at one of these families of microcontrollers from the Espressif company. Additionally, the ESP32 includes Bluetooth v4.2 BR/EDR and BLE (Bluetooth Low Energy) capabilities, which are not available in the ESP8266. This added functionality makes the ESP32 more versatile for wireless communication.
It provides you with a faster processor and good memory size, which allow considerable larger projects to be designed on only one SOC. The two devices are very important tools of IoT but naturally have their own https://traderoom.info/brainwagon-the-esp32-vs-the-esp8266/ function and flaws. Today, in this article we will discuss the two popular microcontrollers. 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 highly durable and is able to function consistently even in harsh industrial environments. When it comes to onboard sensors, the ESP8266 is quite minimalistic; it does not have any built-in sensors. Furthermore, the ESP32 has Bluetooth v4.2 BR/EDR and BLE (Bluetooth Low Energy) capabilities, which the ESP8266 lacks. Technology trends in artificial intelligence (AI) and the IoT have started to merge, a trend that industry has named the Artificial Intelligence of Things (AIoT). The SMA connector is an effective sub-miniature RF and microwave connector that has a screw fixing to provide reliable connectivity.
Arduino compatibility
Svitla Systems will provide you with the necessary resources and a team of testers. To program ESP8266 controllers, there is a real-time SDK ESP8266_RTOS_SDK. All these advantages in general give a unique combination of qualities. Espressif Systems (Shanghai) Pte., Ltd. is a China company that started out in 2008 with a very small group of engineers. Therefore, in terms of programming support and community resources, both the ESP8266 and ESP32 offer extensive options and robust support. One of the main functions of ESP8266 is to host any application or offloading all Wifi networking functions.
RTC MEM moved to LP MEM (low power memory)
Most of the time, you’ll want to use ESP32 and ESP8266 development boards. As a low-power, high-performance Wi-Fi and Bluetooth chip, the ESP32 features a rich set of peripherals and interfaces. First of all, ESP32 and ESP8266 are both very cost-effective Wi-Fi module chips, which are very suitable for projects in the field of the Internet of Things (IoT). ESP32 is a dual-core 160MHz to 240MHz CPU processor, while ESP8266 is a single-core processor with an operating frequency of 80MHz. To assist in making this decision, let’s compare the two microcontrollers. We will examine several aspects beyond just speed, power efficiency, and cost-effectiveness.
