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. The ESP8266 could see upgrades aimed at extending its utility in cost-sensitive applications.
ESP32 vs ESP8266: Core Differences
- It operates on a Tensilica Xtensa LX3 processor and is primarily intended for smart devices, wearables, and Wi-Fi-enabled projects.
- When considering different factors, different modules need to be selected.
- In the end, your selection of a microcontroller will depend more on your project’s specific requirements than hard numbers.
- This provides enough speed for any application that requires a microcontroller with connectivity.
- 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.
The ESP8266 is usually cheaper than the ESP32, making it a more cost-effective option for simple projects. 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. In a broader context, ESP32 devices offer more GPIO options, enhancing their utility in complex applications.
- This is our complete guide to program the ESP32 with Arduino IDE, including projects, tips, and tricks!
- Commonly used development boards include the ESP32 DEVKIT DOIT Development board and the ESP8266 ESP-12E NodeMCU Kit.
- It quickly gained popularity due to its simplicity and low cost.
- In summary, for simple, low-power Wi-Fi-based projects, the ESP8266 is the preferred choice.
- It’s also important that it comes with voltage regular and USB input for power and upload code.
- Not all pins are exposed in all ESP32 development boards, and some pins should not be used.
Processing Power and Memory
Now, let’s check if the installation was successful and if we can upload new code to the ESP32 board. Now, you’re ready to start programming your ESP32 using Arduino IDE. Other similar boards with the features mentioned previously may also be a good option like the Adafruit ESP32 Feather, Sparkfun ESP32 Thing, NodeMCU-32S, Wemos LoLin32, etc. This is also why you can dedicate some of the Flash memory to afile system called SPIFFS or FATFS. That allows you to do some fancy stuffemulating an SD card within the flash memory itself. Wirelessly monitor CCTV cameras and sensors, providing data.
You don’t need that industrial device unless you need ridiculous range. Weather isn’t a huge issue, just buy a cheap project enclosure, cut a hole and add a grommet, then stick the sensor outside of the enclosure. After that, just use heat shrink tubing to close protect the wiring and caulk or hot glue to close up the grommet hole.
It supports both classic Bluetooth 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 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. For beginners, we recommend an ESP32 board with a vast selection of available GPIOs, and without any extra hardware features. It’s also important that it comes with voltage regular and USB input for power and upload code.
ESP32 vs ESP8266 – Pros and Cons
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. Not all pins are exposed in all ESP32 development boards, and some pins should not be used. The ESP32 DEVKIT V1 DOIT board usually comes with 36 exposed GPIOs that you can use to connect peripherals.
The inclusion of small cameras in many ESP32 development boards further positions the ESP32 as a highly capable device. 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. Both the ESP8266 and ESP32 SoC microcontrollers provide hobbyists with an Internet communication device, but the ESP32 is a slightly better option.
However,the ESP32’s ULP processor allows the main system to remain asleep whilehandling simple tasks, providing even greater power efficiency. However, the price difference between the two has been reduced in recent years. Depending on where you’re buying from, you can generally find both boards for sale at more or less the same price. In such cases, the ESP32, with its better connectivity features, can be a better deal at the same price. So, in terms of programming support and community resources, there is little to no competition between the two boards; https://traderoom.info/brainwagon-the-esp32-vs-the-esp8266/ both provide an extensive range of supported languages and resources. The ESP8266 features a 32-bit Tensilica Xtensa L106 single-core processor, running at 80 MHz, which can be overclocked to 160 MHz.
However, it has some limitations in the GPIO mapping, and it might not have enough pins for what you intend to do. Another popular way of programming the ESP32 and ESP8266 boards is using MicroPython firmware. While the ESP32 can cost around $6 to $12, the ESP8266 can cost $4 to $6 (but it really depends on where you get them and what model you’re buying). In this article, we’ll compare the ESP32 with the ESP8266 and cover the pros and cons of each board.
