ESP32 vs ESP8266, Which is Better and How to Choose? Embedded Technology Information EmbedIc

esp32 vs esp8266

The ESP32 offersmore capabilities but has a steeper learning curve (although core WiFioperation is the same), while the ESP8266 remains a cost-effectivesolution with significant functionality. Regardless of the choice, bothmicrocontrollers excel in building IoT systems with WiFi connectivityand the flexibility of the Arduino IDE. The ESP8266 was very popular because it only cost a few dollars and allowed anyone to program an inexpensive microcontroller with Wi-Fi capabilities.

Defining the Display Width and Height

The ESP32 comes with a dual-core Tensilica processor clocked at 160MHz and has 448KB of ROM and 520KB of SRAM. It also supports Ethernet, CAN bus, and other communication protocols. The ESP32 is the newer of the two, released in 2016, and is a more powerful and feature-rich microcontroller. It has Wi-Fi and Bluetooth capabilities and is also widely used in the IoT industry. When it comes to choosing the right microcontroller for your IoT project, the two most popular options are the ESP32 and ESP8266.

By following these best practices, you can help to ensure that your microcontroller-based system is as secure as possible. The ESP32 has a crypto engine that can be used to perform cryptographic operations. The ESP8266 does not have a crypto engine and thus cannot be used for applications that require cryptographic operations. The price of an ESP32 chip ranges from $5 to $10, while the price of an ESP8266 chip ranges from $2 to $5. The power consumption of the ESP32 is very slightly higher than that of the ESP8266. Robin Mitchell is an electronic engineer who has been involved in electronics since the age of 13.

Microcontroller Unit

While the ESP32 does support AT commands for being controlled via an external microcontroller, it is often used as the primary microcontroller. Failure to specify these functions in the code will result in default pin assignments, illustrated in the accompanying diagram. It’s important to note that this example pertains to the ESP32 DEVKIT V1 DOIT board (36 GPIO version), and pin locations may vary based on the manufacturer. While both boards are cost-effective, the ESP32 is slightly pricier. The ESP32 typically ranges from $6 to $12, while the ESP8266 can be found in the $4 to $6 range (actual costs may vary based on the source and specific model).

ESP32 vs. STM32: GPIOs

The ESP32 surpasses the ESP8266 in terms of GPIO count, affording you the flexibility to designate specific pins for UART, I2C, and SPI functionalities by configuring the code. This capability stems from the ESP32 chip’s multiplexing feature, enabling the assignment of multiple functions to a single pin. Commonly used development boards include the ESP32 DEVKIT DOIT Development board and the ESP8266 ESP-12E NodeMCU Kit. The primary role of the ESP8266 is to either host applications or offload all Wifi networking functions.

Nevertheless, over time, these issues are expected to be addressed, allowing both boards to excel in their respective applications. 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. Notably, the ESP32 incorporates touch-sensitive pins for waking up from deep sleep, an integrated hall effect sensor, and, in earlier versions, a built-in temperature sensor (though recent versions omit this feature).

This would allow more complex algorithms to run locally on the device, reducing latency and reliance on cloud services. Additionally, improvements in security features, such as more robust encryption methods and secure boot processes, are likely to be prioritized to safeguard against increasing cyber threats. MicroPython stands as a reinterpretation of Python 3 tailored specifically for microcontrollers and embedded systems. It closely resembles conventional Python, implying that if you possess proficiency in Python programming, you inherently possess the skills to program in MicroPython.

Furthermore, both boards support programming in MicroPython, Lua, JavaScript, and other languages (a full list is available on the wiki), making them accessible to a wide range of programmers. In addition, the developer community around both modules is robust and active, with an abundance of online forums, extensive libraries, and tutorials. Let’s begin with a comparison of the two to help you make a decision.

Sometimes one is preferred over the other when it comes to certain elements in question. The ESP8266 has a lower current consumption than that of its competitor however one has more digital pins than the other. 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. While the ESP32 costs about 22 to 40 RMB, the ESP8266 costs 12 to 30 RMB (but it really depends on where you get them from and what model you buy).

Development boards based on ESP32 and ESP8266 supports both Arduino IDE and Micropython. Since ESP32 is new and more popular, the libraries(Arduino IDE) are constantly updated for it. ESP32-based development boards are also the first to get support for new modules/devices. 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.

On the other hand, the ESP8266 is a low-cost Wi-Fi microcontroller often used for IoT projects and home automation. Despite its limited processing power and memory compared to the ESP32, the ESP8266 is easier to use and has a large community of users and resources available. The board supports the 802.11b/g/n Wi-Fi standard but lacks the Bluetooth capability of the ESP32. Microcontrollers have many of the same components as a regular CPU, such as a central processing unit (CPU), memory, and input/output (I/O) interfaces.

It offers a single-core processor and is known for its simplicity, making it an attractive choice for entry-level projects and applications where Wi-Fi connectivity is the primary requirement. The ESP32, developed by Espressif Systems, is a dual-core microcontroller that offers built-in Wi-Fi and Bluetooth capabilities. Its powerful processing capabilities and extensive set of features make it suitable for a wide range of applications, from IoT projects and home automation to wearables and industrial solutions. It is apparent that both the ESP32 and ESP8266 serve as remarkable toolkits.

After completing a BEng at the University of Warwick, Robin moved into the field of online content creation developing articles, news pieces, and projects aimed at professionals and makers alike. Currently, Robin runs a small electronics business, MitchElectronics, which produces educational kits and resources. To compare the two different devices, it is best to tabulate the data to get a better idea of what each device can offer. The choice between the two boards depends on your specific needs, as each offers distinct advantages and drawbacks. Notably, in MicroPython, the majority of Python scripts exhibit compatibility with both boards, in contrast to the Arduino IDE.

Due to higher clock speed, ESP32 performs tasks faster than ESP8266. One of the main functions of ESP8266 is to host any application or offloading all Wifi networking functions. It is highly durable and is able to function consistently even in harsh industrial environments. The Development Kit based on ESP8266, integates GPIO, PWM, IIC, 1-Wire and ADC all in one board.
