ESP32 vs ESP8266: How to Choose the Right Microcontrollers

In most of our ESP32 projects, we use the ESP32 DEVKIT DOIT board, and that’s the one we recommend for beginners. There are different versions of this board with a different number of available pins (30, 36, and 38)—all boards work in a similar way. When you create a useful IOT device such as an ESP8266 it willinevitably be used for stand alone battery powered operation. There’s abig problem in that when a 32bit processor is operating at160/80MHz  (240/160MHz for the ESP32) then power consumption willbe through the roof. Config in ESPHome is extremely simple and ESPHome supports OTA updates.

The ESP32 is a series of chip microcontrollers developed by Espressif. For both the ESP32 and the ESP8266 you can choose a low poweroperating mode – you can periodically wake the processor to transmitdata over WiFi as needed, and this will save a lot of power. However, Inthe low power sleep modes you can’t do a lot – only react to interruptsetc. So the main difference comes down to speed, and for the ESP32 that istwice the speed of the ESP8266. Additionally the ESP32 has a dual corearchitecture further enhancing performance.

The ESP32 and ESP8266 are cheap Wi-Fi modules perfectly suited for DIY projects in the Internet of Things (IoT) and Home Automation fields. It’s a good practice to periodically ensure you have the latest version of the ESP32 boards installed. In Arduino IDE 2, you’ll receive a pop-up notification prompting you to update whenever a new version becomes available. Wait a few seconds while the code compiles and uploads to your board.

ESP32 vs ESP8266 – Pros and Cons

1. 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.
2. The picture below shows the ESP32 DEVKIT DOIT V1 board, version with 36 GPIO pins.
3. On the contrary, in our opinion, it is as easy to program the ESP32 as the ESP8266, especially if you intend to program it using the “Arduino language” or MicroPython.
4. Therefore, the specific choice of ESP32 and ESP8266 can only be made based on your actual application.

This is our complete guide to program the ESP32 with Arduino IDE, including projects, tips, and tricks! These are good news, especially for those used to program the Arduino board and are familiar with the Arduino “programming language”. There are many ways to program the ESP32 and ESP8266 boards. Both boards can be programmed with the Arduino core using the Arduino IDE or other IDEs (like VS Code with the PlatformIO extension). The ESP32 supports Bluetooth communication protocol by default, while the ESP8266 doesn’t.

What is the best ESP32 development board for beginners?

If you have an ESP32 DEVKIT DOIT board, the built-in red LED will turn on. This board also comes with a RESET button (may be labeled EN) to restart the board and a BOOT button to put the board in flashing mode (available to receive code). It comes with a microUSB interface that you can use to connect the board to your computer to upload code or apply power. This particular ESP32 board comes with 36 pins, 18 on each side. I have been working withwireless temperature and humidity sensor. I want your suggestions, which one is better between esp32 or esp8266 to send this sensor data to HA.Any leads will be a great help.Thanx.

Built-in Sensors

1. Both the ESP8266 and ESP32 are supported by the Arduino IDE and the native ESP-IDF (Espressif IoT Development Framework).
2. However, Inthe low power sleep modes you can’t do a lot – only react to interruptsetc.
3. That said, if youreally need ulra low power battery operation then this is the way to doit.
4. It comes with a microUSB interface that you can use to connect the board to your computer to upload code or apply power.
5. When comparing two microcontrollers, it’s important to know what types of peripheral interfaces they have.
6. At this time, you can choose to use ESP32 or ESP8266 according to the needs of the project.

In any case, both devices are good representatives of their niches. WiFi Direct is also supported by the ESP32, which is a suitable alternative for peer-to-peer connections that don’t require an access point. It is easier to set up WiFi Direct and has substantially faster data transmission speeds than Bluetooth. The chip also supports both Bluetooth 4.0 (BLE/Bluetooth Smart) and Bluetooth Classic (BT), making it even more versatile.

If you’re familiar with the ESP8266, the ESP32 is its successor, loaded with lots of new features. ESP32 is a series of low-cost chip microcontroller power systems. The ESP32 series is created and developed by Espressif Systems.

This table serves as a reference point, summarizing each microcontroller’s capabilities and offerings. For the ESP32, future upgrades may focus on enhancing its AI and machine learning capabilities, possibly incorporating dedicated neural processing units (NPUs) for edge computing tasks. This https://traderoom.info/brainwagon-the-esp32-vs-the-esp8266/ 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. An alternative and widely embraced approach to programming the ESP32 and ESP8266 boards involves the utilization of MicroPython firmware.

The ESP32 also has far moreSRAM than the ESP8266; actually four times the ESP8266 SRAM. Expensive device, I would only be looking at that if you really need it’s features such as range and robustness to weather. Otherwise you can build a wifi device from an esp for under 10% of that cost.

The ESP32 has a 32-bit processor with an ultra-low-power coprocessor and multiple input/output connectors, including digital-to-analog converters. ESP32 provides a secure platform for the Internet of Things. ESP32 is an upgraded version of ESP8266, it has 34 GPIO pins and comes with Xtensa dual-core processor 160MHZ. But this doesn’t mean the ESP32 is a better choice in every case. In the end, your selection of a microcontroller will depend more on your project’s specific requirements than hard numbers.

The growing viability of secure socket layer (SSL) connections is tied to the expanding memory and processing power, crucial factors in a society prioritizing security. The ESP32, boasting greater power, an expanded array of GPIOs with multifunction capabilities, faster Wi-Fi, and Bluetooth support, stands as a more advanced option. Although some find it more complex, especially compared to the ESP8266, programming the ESP32 can be straightforward, especially when utilizing the Arduino language or MicroPython. MicroPython stands as a reinterpretation of Python 3 tailored specifically for microcontrollers and embedded systems.

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. The ESP32 chip adds additional CPU cores, faster WiFi transmission technology and more GPIOs, and supports Bluetooth 4.2 protocol and Bluetooth Low Energy. In addition, the ESP32 chip is equipped with touch-sensitive pins, which can be used to wake up ESP32 to deep sleep, a built-in hall-effect sensor and a built-in temperature sensor.
