In addition, the developer community around both modules is robust and active, with an abundance of online forums, extensive libraries, and tutorials.
ESP32 vs ESP8266, Which is Better and How to Choose?
In conclusion, the ESP32 and ESP8266 are excellent choices for building IoT projects, and the best one depends on your project’s specific requirements. The ESP32 is ideal for complex projects requiring more computational power, while the ESP8266 is a better choice for simple, easy, and cost-effective simple tasks. Ultimately, both boards offer a powerful platform for building IoT projects and allow you to bring your ideas to life effortlessly. A flexible Wi-Fi+BT+BLE MCU module, the ESP32 can be used for a variety of tasks, from low-power sensor networks to the most demanding ones like voice encoding, music streaming, and MP3 decoding. It includes a power amplifier, low-noise amplifiers, filters, and a power management module in addition to an integrated antenna and RF balun.
How long does it take for ESP8266 to wake up during light sleep?
Let’s consider some common application use-cases and let’s see how much memory these use-cases consume of ESP32 and ESP32-C3 SoCs and what headroom is available for the application. ESP32-C3 doesn’t require Bluetooth memory to be contiguous and at fixed location. ESP32-C3 Bluetooth subsystem allocates memory using standard system heap and hence Bluetooth can be enabled and disabled by the application as and when required. In case of ESP32-C3, there is no static partitioning of IRAM and DRAM.
ESP32 vs ESP8266 – Which One To Choose?
It offers fast processors and high memory, which is best for larger projects that are made on a single SOC. ESP32 is a high clock speed controller board that is the successor of ESP8266. It comes with a dual https://traderoom.info/ cor CPU with clock speed frequency of 160MHz to 240MHz with inbuilt WiFi and Bluetooth module. Choosing the right board for an IoT project can be challenging, as several factors need to be considered.
Sensors, Transducers
ESP8266 power consumption is comparatively low for such solutions with WiFi. Also, it has a very good option to go into sleep mode, where power consumption is unbelievably low (1.0 mW). Recently, the use of the updated Wi-Fi module ESP8266, version ESP-01S (based on the ESP8266EX chip with a built-in TCP/IP protocol stack and AT command management), has become very popular. The chip is designed for use in smart outlets, mesh networks, IP cameras, wireless sensors, wearable electronics, and so on. The ESP32 is more powerful than the ESP8266, includes more GPIOs with multiple functions, faster Wi-Fi, and also supports Bluetooth.
- The choice between a CPU and a microcontroller depends on the specific requirements of the application.
- The ESP32 has embedded flash memory of different sizes and supports multiple external QSPI flash and SRAM chips (up to 16MB).
- 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.
- According to Cisco’s Annual Internet Report, by 2023 there will be nearly 30 billion network-connected devices (in 2018 there were around 18.4 billion).
- To program Espressif ESP-32 microcontrollers, there is an ESP-IDF development environment.
As a result, they may be of more interest to projects that require higher performance, more complex functionality, and broader support for these development boards. The ESP32 is an upgraded version of the ESP8266, and works in a very similar way. The ESP32, unlike the ESP8266, also features integrated Bluetooth v4.2 which increases its connectivity options and supports Bluetooth low-energy (BLE) mode.
ESP32 is more powerful than ESP8266 in terms of processor, speed, memory, and number of GPIO pins. The ESP32 has embedded flash memory of different sizes and supports multiple external QSPI flash and SRAM chips (up to 16MB). The ESP8266 features a 32-bit Tensilica Xtensa L106 single-core processor, running at 80 MHz, which can be overclocked to 160 MHz.

It describes some of the problems that designers face with power sourcing and provides some solutions.
However, the ESP8266 has some limitations in GPIO mapping and does not have enough pins to operate. The ESP32 has more GPIOs than the ESP8266, and you can decide which pins are UART, I2C, SPI – you need to set this in https://traderoom.info/brainwagon-the-esp32-vs-the-esp8266/ your code. This is possible because the multiplexing feature of the ESP32 chip allows you to assign multiple functions to the same pin. However, the price difference between the two has been reduced in recent years.
The ESP8266, being more budget-friendly than the ESP32, serves well for straightforward DIY IoT projects despite having fewer features. Its “older” status results in better software support, making it easier to find assistance. Nevertheless, limitations in GPIO mapping and potential pin insufficiency may prompt the use of the ESP32 for more complex tasks. The usefulness of AT commands is that the ESP8266 is pre-programmed to run AT commands when sent out of the factory and can be connected straight to a microcontroller’s UART port. From there, a microcontroller can make requests to connect to Wi-Fi, connect to servers, and send or receive data.
The ESP32, with its enhanced features and capabilities, is slightly more expensive but offers better processing power and versatility. Understanding the peripheral interfaces of microcontrollers is crucial when comparing them. These interfaces enable communication with sensors and other devices, significantly influencing the complexity and variety of projects you can undertake.
Suppose you’re building a smart home system that controls the lighting and temperature in your home using a mobile app. In this case, you need a board with Wi-Fi connectivity, enough GPIOs to connect to a few sensors and actuators, and low power consumption, as the system will run 24/7. Additionally, both microcontrollers support programming in MicroPython, Lua, JavaScript, and other languages (a comprehensive list is available on their wiki). The developer community for both boards is large and active, offering plenty of online forums, extensive libraries, and tutorials.
The ESP32 module with 4 MB PSRAM memory, which is built on the ESP32-D0WDQ6 chip from Espressif, is becoming very popular among developers. In fact, between ESP8285 and ESP32, there is also an intermediate solution ESP8285. This is a great option if your project does not have enough memory or computing resources, but at the same time, ESP32 is redundant. 2 Built-in Bluetooth and WiFi functionality, eliminating the need to purchase additional modules and reducing costs. 2 The ESP32 and ESP8266 are relatively inexpensive, making them suitable for low-cost IoT projects and prototyping.
