esp32 vs esp8266 memory

Since many ESP32 development boards come with small cameras, this suggests that the ESP32 is a very capable board. The ESP8266 is better suited for situations where an application must use a microcontroller for historic reasons that require an Internet connection to help modernise it. Espressif Systems is known for its popular microcontrollers, ESP32 and ESP8266.

Long-Term Project Goals

The ESP8266 does not have an RTC and thus cannot be used for applications that require time tracking. Therefore, if you are building a simple IoT project, the ESP8266 may be able to do so at a lower price. However, as time goes on and ESP32 is widely adopted, these differences in development and libraries will not be noticed. Since the ESP8266 has been on the market for a longer time, it can get more support in terms of software and will be easier to use and more compatible.

It can connect a variety of sensors, actuators, and external devices. Understood.I am a retired professional and I avoid it because it simply is not necessary for Arduino projects and it is not suitable for posting on this forum or other “arduino’ish” forums. Both have 32-bit processor, ESP32 is dual core 80Mhz to 240MHz CPU and ESP8266 is 160MHz single core  processor.

Power Consumption

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. The DOIT Esp32 DevKit v1 is one of the development board created by DOIT to evaluate the ESP-WROOM-32 module. It is based on the ESP32 microcontroller that boasts Wifi, Bluetooth, Ethernet and Low Power support all in a single chip. ESP32 DevKit contains ESP32-WROOM, 3.3V power supply required for ESP32 and USB to serial converter  for easy programming.

What is ESP32 module?

Microcontroller programming is usually done in assembler or C, although there are compilers for other languages, such as microPython or Lua. A key feature of the module is the ability to connect an external antenna through the U.FL connector. 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. 4 Although the ESP8266 has a relatively small number of GPIO pins, usually between 10 and 17, this is still enough to meet the needs of many simple applications.

  1. 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.
  2. In addition, because ESP8266 has been on the market for a long time, it can get more support in terms of software, making it more convenient and compatible to use.
  3. ESP32-S3 features a full-speed USB OTG interface along with an integrated transceiver.

Sensors, Transducers

Most places around cities, towns, highways and even estates are lit during dark hours or at night in most regions of the country. Manual control of these lights can prove to be difficult and at times inconvenient. One of the solutions that are most commonly used is timers, however, this approach can be quite limited in some time zones where the length of day varies throughout the year. Households and workplaces have become some of the most common places to spend most of our day. Regardless of the size or space available, it is imperative that these spaces be made as comfortable as possible to have a suitable environment.

Some of the popular libraries, such as the WiFi and Ethernet libraries, are not compatible with the ESP32. This means that you will have to find alternatives to these libraries or use different hardware if you want to use these libraries with your ESP32. The ESP32 consumes more power than the ESP8266, which can be a problem if you are using batteries to power your project. When it comes to low-cost, low-power consumption chips, there are a few alternatives to ESP32 and ESP8266. The most popular ones include the CC3200 from Texas Instruments and the Nordic nRF52840.

Nevertheless, both devices stand as commendable representatives within their respective niches. Both chips may benefit from the ongoing miniaturization trend, resulting in smaller, more energy-efficient modules that can be deployed in a wider range of IoT devices, from wearables to smart home products. This could also involve better support for battery-less operations, using energy harvesting technologies to power devices, making IoT solutions more sustainable and easier to maintain. The ESP8266 could see upgrades aimed at extending its utility in cost-sensitive applications. These might include slight improvements in processing power and memory, while maintaining its low price point.

In addition, the ESP32 contains 10 capacitive sensing GPIOs that can detect touches and can be used to trigger events or wake up the ESP32 from deep sleep. Both microcontrollers have advanced power-saving features to minimize energy consumption effectively. This boost in processing power and memory makes the ESP32 ideal for more intensive applications. When it comes down to choosing between the ESP8266 and ESP32, it all depends on your specific needs. If you’re on a tight budget and don’t need any extra features, the ESP8266 is a great choice.

However, by understanding your project’s requirements and the capabilities of different boards, you can make an informed decision that will ensure the success of your project. Both the ESP8266 and ESP32 are compatible with the Arduino IDE and Espressif’s native ESP-IDF (Espressif IoT Development Framework). The Arduino IDE is great for smaller projects, but for more complex applications, it’s better to use ESP-IDF with the Visual Studio Code extension or the Eclipse plugin.

I care because this program is a base for future programs that I predict will be much larger. If a simpler program already takes 61% of the space I possibly may have program space issues in the near future. That is an issue I didn’t think I’d have for a long time with a base sketch I started on an nodeMCU that took up only 34%. Perhaps the ESP32 is not a good choice if its code base, dual core architecture, compiler results or libraries balloons code quickly. Prefer not to already think about about a more expensive ESP32 with larger memory.
