The ESP8266 was very popular because it only cost a few dollars and allowed anyone to program an inexpensive microcontroller with Wi-Fi capabilities. The ESP32 is even cheaper than the ESP8266, but its capabilities are much greater.

It is designed to perform a range of tasks recorded in the firmware in the memory of the device. Affordable microcontrollers and convenient firmware development environments also contributed to this widespread use of proprietary IoT development. 1 The energy-efficient design is low, which may have some impact on battery life, especially in low-power applications that need to run for long periods of time. Both microcontrollers offer strong community support and are accessible to beginners, making them excellent choices in their respective niches. In the dynamic world of microcontrollers, the ESP32 and ESP8266 have emerged as popular choices for hobbyists and professionals. This comprehensive guide will explore the strengths and weaknesses of ESP32 vs ESP8266, offering insights to help you choose the best microcontroller for your needs.

  4. Unlike the ESP8266, the ESP32 chip includes both Wi-Fi and Bluetooth connectivity options.

In summary, for straightforward, low-power Wi-Fi projects, the ESP8266 is the better option. If your project requires more processing power, additional memory, and features like Bluetooth, the ESP32 is the superior choice. Released in 2014 by Espressif Systems in Shanghai, China, the ESP8266 is a budget-friendly Wi-Fi microchip featuring an integrated TCP/IP stack and microcontroller capabilities. It is powered by a Tensilica Xtensa LX3 processor and is mainly used in smart devices, wearables, and Wi-Fi-enabled projects.

The ESP8266 is easier to use than the ESP32, but it’s not as powerful. The ESP32 is more versatile and can be used for a wider range of applications, but it’s not as easy to use. The ESP32 is a microcontroller unit (MCU), while the ESP8266 is a system-on-chip (SoC). This means that the ESP32 is a complete standalone device, while the ESP8266 requires an external microcontroller to function. In addition, the ESP32 has several built-in peripherals, including a capacitive touch sensor, Hall effect sensor, low-noise amplifier, SD card interface, Ethernet MAC and LCD controller. Both ESP32 and ESP8266 can be programmed using the same Arduino IDE framework.

It depends on the application and the development team’s expertise. If you’re just getting started with microcontrollers, the ESP8266 is the better choice. If you need a more powerful microcontroller for your project, the ESP32 is the better choice.

Both boards are inexpensive, but the ESP32 is slightly more costly. 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). Here’s a table that compares the ESP8266 and ESP32 specifications and features in depth. This table serves as a reference point, summarizing each microcontroller’s capabilities and offerings. Both the ESP8266 and ESP32 are supported by the Arduino IDE and the native ESP-IDF (Espressif IoT Development Framework).

It adds an additional CPU core, faster Wi-Fi, more GPIOs, and support for Bluetooth 4.2 and Bluetooth Low Power. 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.

While all ESP32 devices work in nearly identical ways, the specific device that will be used in the series to come will be the Adafruit Huzzah32. Another way to program ESP32 and ESP8266 boards is to use MicroPython firmware. MicroPython is a reimplementation of Python 3 for microcontrollers and embedded systems.

In MicroPython, most Python scripts are compatible with both boards (unlike when using the Arduino IDE), and the same scripts can be used for both ESP32 and ESP8266. It adds extra CPU cores, faster Wi-Fi, more GPIOs, and supports Bluetooth 4.2 and Bluetooth Low Energy. In addition, the ESP32 is equipped with touch-sensing pins that can wake up the ESP32 from deep sleep, a built-in Hall effect sensor, and a built-in temperature sensor. Both ESP32 and ESP8266 WiFi modules have GPIO and support various protocols such as SPI, I2C, and UART. The best part is that they come with wireless networking, which sets them apart from other microcontrollers like Arduino. This means you can easily control and monitor your device remotely via Wi-Fi or Bluetooth (ESP32) at a fraction of the price.

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 does have a ULP (Ultra Low Power) processor that is anentirely separate processor which can do simple tasks, even while themain system is asleep. The big problem with this processor is that ithas a subset language and is very difficult to use. That said, if youreally need ulra low power battery operation then this is the way to doit. It can be inferred that both the ESP32 and the ESP8266 are amazing toolkits.
