The execute-in-place approach from QSPI memory reduces the dependence on large on-chip memory. This scalability benefits cost-sensitive and compact applications, such as portable devices. This strategy is preferred for integrating larger programs without increasing costs. ESP32 is better than ESP8266 because ESP32 has extra features such as CPU core, Faster Wi-Fi, Bluetooth 4.0 (BLE), touch sensitivity pins, and built-in Hall Effect sensors and temperature sensors. The ESP32 contains 10 capacitive GPROS that detect touch and can be used to trigger events.
ESP32 vs ESP8266: Core Differences
If you need higher processing power, Bluetooth connectivity, and more GPIO pins, the ESP32 would be the better option. However, if you are working on a simpler project with basic Wi-Fi requirements and cost-efficiency is a priority, the ESP8266 could be more suitable. The ESP32 excels with dual communication support, handling both Wi-Fi and Bluetooth to ensure smooth device connectivity and data exchange.
This table serves as a reference point, summarizing each microcontroller’s capabilities and offerings. 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.
My personal recommendation is the ESP32 C3 breakout board (available for under EUR 3.00). It uses one of the most modern ESP microcontrollers, specificly one with native USB support, and comes in miniature form factors that fits even the smallest DIY devices and specializes in energy savings modes. The ESP32 and Raspberry Pi differ in terms of operating systems and capabilities. The ESP32 runs on an RTOS (Real-Time Operating System), which is lightweight and designed for more real-time, low-power applications. The ESP32’s adept power management, courtesy of its ultra-low-power co-processor, provides immense benefits in applications prioritizing energy conservation. This capability is attractive in remote monitoring systems and portable IoT devices, where prolonging battery life becomes a central focus.

- This explains why the ESP8266 remains a popular choice for many, despite not being the top performer.
- In fact, between ESP8285 and ESP32, there is also an intermediate solution ESP8285.
- The board supports the 802.11b/g/n Wi-Fi standard but lacks the Bluetooth capability of the ESP32.
- Its core power stems from the option of dual-core or single-core Tensilica Xtensa LX6 processors, reaching speeds up to 240 MHz.
ESP8266 is a Wi-fi SoC that has all the important components that users need to use Wi-fi devices. The ESP8266 is a low-cost Wi-Fi enabled microchip that can add wireless connectivity to any microcontroller. Subsequent models, such as the ESP32-C and -S series, introduced both single and dual-core variations, utilizing a Risc-V CPU model in place of Xtensa. Risc-V, akin to the widely supported and recognized ARM architecture, distinguishes itself with its open-source nature and user-friendly characteristics.
Power Management
The ability to execute DSP tasks directly on the processor streamlines system design, cutting down on additional components and costs. Let’s compare the two modules using the Arduino IDE, which is mostly used to program the ESP32 and ESP8266 microcontrollers. Both boards can be programmed using the Arduino IDE, which is a benefit for individuals who are familiar with the platform.
- You can utilize the VIN pin to power the ESP8266 and its peripherals directly if providing power through 5V source.
- The ESP8266 offers both BSS Station and SoftAP modes, showcasing flexibility in network configurations.
- Add Wi-Fi, Bluetooth (for the ESP32), and low-power consumption, and we have the bestseller among microcontrollers.
- On the other hand, the ESP8266, while less capable than the ESP32, remains astronomically employed for lower-worrisome IoT operations due to its sensibility and ease of application.
In MicroPython, most Python scripts are compatible with both boards (unlike when using Arduino IDE). This means that most of the time, you can use the same script for ESP32 and ESP8266. These are good news, especially for those used to program the Arduino board and are familiar with the Arduino “programming language”. The ESP32 supports Bluetooth communication protocol by default, while the ESP8266 doesn’t. 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.
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. To program Espressif ESP-32 microcontrollers, there is an ESP-IDF development environment. This is the official development framework for the ESP32 and ESP32-S Series SoCs. It has Wi-Fi and Bluetooth radio channels, a dual-core microcontroller, a rich set of built-in peripherals, and is a certified “FCC part 15.247”.
In such cases, the ESP32, with its better connectivity features, can be a better deal at the same price. Both boards have advanced power-saving technologies to minimize power consumption effectively. 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. ESP8266 Pro is a product from the past when the price difference between ESP8266 and ESP32 was still huge. In which case you should get an ESP32.For the price of a ESP8266 Pro you can get a ESP32 as well when you look around a bit.
The inclusion of Ethernet MAC and CAN bus broadens its utility in automotive and industrial contexts, ensuring reliable and swift data transmission. The implementation of practical energy management strategies, https://traderoom.info/brainwagon-the-esp32-vs-the-esp8266/ such as sleep modes and dynamic frequency scaling, extends battery life in portable devices. In practical settings, configuring these power-saving methods to suit specific requirements becomes a focal point.

By adhering to ECOPACK® standards, the STM32 reflects a dedication to environmental responsibility, minimizing hazardous substances during production. This approach resonates with contemporary design philosophies that emphasize sustainability. Potent debugging tools streamline the development process, allowing for accurate error detection and enhanced performance tuning. You can experience a smoother workflow, quickening the pace of product development cycles.
The ESP32 microcontroller is packed with features, including dual-core processing power, Bluetooth, and Wi-Fi. Its ability to manage intricate jobs effectively enables it to be the perfect choice for applications requiring exceptional performance. It was developed for the lack of security, which is implemented in the ESP8266. It is apparent that both the ESP32 and ESP8266 serve as remarkable toolkits. Preferences may sway towards one or the other based on specific considerations.
However, for simple projects where wireless connectivity or extra processing power is not required, the Arduino Uno may still be a good choice due to its simplicity and large community support. If your project requires basic Wi-Fi connectivity, and minimal processing power, the ESP8266 is an excellent choice. It’s ideal for simple IoT devices where keeping costs low is crucial, making it perfect for cost-sensitive projects. The ESP8266 is also suitable if you don’t need many GPIO pins or advanced peripherals, addressing limited hardware needs efficiently. For those new to IoT and microcontrollers, it’s a great starting point for educational purposes due to its simplicity and ease of use. The ESP-12E module on the development board contains an ESP8266 chip with a Tensilica Xtensa 32-bit LX106 RISC microprocessor that supports RTOS and operates at 80 to 160 MHz adjustable clock frequency.
When embarking on an IoT or embedded systems project, choosing the right microcontroller can be a hassle. Espressif Systems created the ESP8266 and the ESP32, which are two popular options in the maker community. While they share some similarities, they also have key differences that can significantly impact your project’s performance or complexity.
