ESP32 vs ESP8266: Choose the Right Wi-Fi Microcontroller

ESP32 vs ESP8266: Choose the Right Wi-Fi Microcontroller

MicroPython is a re-implementation of Python 3 targeted for microcontrollers and embedded systems. So, if you already know how to program in Python, you also know how to program in MicroPython. The following table shows the main differences between the ESP8266 and the ESP32 chips (table adapted from AMICA_IO). 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). Also, a huge plus is the availability of two software development options for these controllers – through the native compiler and through the Arduino environment. In general, the ESP8266 and ESP32 controllers do not compete with each other – they perform different tasks.

5 Programming can be done using the Arduino development environment, supporting open-source projects and enabling fast development. However, the ESP8266 and ESP32, as microcontroller chips specifically designed for wireless connectivity, have built-in WiFi and Bluetooth functionality and offer lower power consumption and cost. For projects that focus on wireless communication and energy efficiency, the ESP8266 and ESP32 may be more suitable for their needs. With excellent performance and rich functionality, the chip provides reliable support for the connection and data transmission of IoT devices.

We will add here the presence of additional RAM data, which allows you to run the microPython programming language on the controller. This chip is convenient to use in conjunction with the ESP32 development module, which makes it easy to create rapid prototypes since you do not need to design your own PCB. ESP 8285 with almost the same price provides more resources and performance, compared with ESP8266.

Full Comparison

The family of ESP microcontrollers can be effectively used in IoT projects of varying complexity. The ESP32 emerges as the overall winner, earning the title of the top Wi-Fi-enabled MCU. Your decision should be guided by your project’s specific needs rather than just performance metrics. While the ESP32 excels in many areas, it lags behind in simplicity and power efficiency, which is why the ESP8266 remains popular for many users. Both microcontrollers have advanced power-saving features to minimize energy consumption effectively. These integrated sensors in the ESP32 provide more functionality out of the box, reducing the need for additional components in your projects.

The best part is that they come with WiFi to communicate with the internet, which sets them apart from other microcontrollers like Arduino. This means that you can easily control and monitor devices remotely via WiFi technology or Bluetooth technology (ESP32) at a very low price. The ESP32 is much more powerful than the ESP8266, comes with more GPIOs with multiple functions, faster Wi-Fi, and supports Bluetooth. However, many people think that the ESP32 is more difficult to deal with than the ESP8266 because it is more complex.

The Ompact of Internet of Things and Smart Devices in Automation

The ESP32 supports Bluetooth communication protocol by default, while the ESP8266 doesn’t. Moreover, the ESP32 contains 10 capacitive sensing GPIOs, that detect touch and can be used to trigger events, or wake-up the ESP32 from deep sleep, for example. You can set PWM signals in any GPIO with configurable frequencies and duty cycle set on the code. For means of comparison, here’s the pinout diagram for the ESP8266 ESP-12E NodeMCU Kit.

Comparison Table Between ESP32 vs ESP8266

• Instead, we’ll consider various factors, including processing power, connectivity features, hardware specifications, development environments, pricing, and more.
• Therefore, in terms of programming support and community resources, both the ESP8266 and ESP32 offer extensive options and robust support.
• The ESP8285 module is a continuation of the ESP8266 line and has a higher degree of integration and reduced dimensions.
• In addition, the developer community around both modules is robust and active, with an abundance of online forums, extensive libraries, and tutorials.

Many ESP32 development boards come with small cameras and it is said to be a very capable board. In summary, for simple, low-power Wi-Fi-based projects, the ESP8266 is the preferred choice. On the other hand, if you need more processing power, extra memory, and features like Bluetooth, the ESP32 is the clear winner.

If you need higher processing power, more GPIO pins, larger memory resources, and a better energy-efficient design, the ESP32 may be a better choice. Both development boards have their own application space, according to the needs of the project to choose the more cost-effective can be. 1 Dual-core processor capable of multi-threaded real-time processing.2 High-speed main frequency of 240MHz, providing fast performance. 4 Built-in Bluetooth and WiFi functionality, eliminating the need to purchase additional modules and reducing costs.

The ESP8266 is a complete or self-contained system on a chip (SOC) circuit, Wifi module with IP/TCP protocol stack. The ESP8266 gives access to any microcontroller through your Wifi connection. The ESP8266 is a low-cost Wi-Fi microchip with a built-in TCP/IP stack and microcontroller capability, released in 2014 by Espressif Systems in Shanghai, China. 3 High-speed main frequency of 240MHz, providing fast performance. ESP32 has a larger memory capacity, which allows ESP32 to handle more complex applications and larger amounts of data.

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. The ESP32 is a dual-core 160MHz to 240MHz CPU, whereas the ESP8266 is a single-core processor that runs at 80MHz.

This boost in processing power and memory makes the ESP32 ideal for more intensive applications. These integrated sensors in the ESP32 provide more functionality out of the box, allowing you to create projects without the need for additional components. https://traderoom.info/brainwagon-the-esp32-vs-the-esp8266/ It operates on a Tensilica Xtensa LX3 processor and is primarily intended for smart devices, wearables, and Wi-Fi-enabled projects.
