Hello friends, today we will talk about two popular microcontrollers, the ESP32 and ESP8266.
Two low-cost microcontrollers commonly used as IoT devices. Both of these functions can interact with other IoT platforms. Both of these devices are very important tools for the Internet of Things, but of course they also have their own capabilities and weaknesses.
ESP32 is a family of low-cost on-chip power system microcontrollers. The ESP32 is a further development of the ESP8266 family. The ESP32 family was created and developed by Espressif Systems. ESP32 has dual cores and an ultra-low power co-processor. It is designed for insufficient security built into the ESP8266
Advantages:
Cons:
ESP8266 is a complete or stand-alone system-on-chip (SOC) integrated circuit, WiFi module with IP/TCP stack. The ESP8266 allows access to any microcontroller via a WiFi connection.
One of the main functions of the ESP8266 is to host any application or offload all WiFi network functions. It is extremely durable and works reliably even in harsh industrial environments.
This is only due to its wide operating temperature range. It also offers an energy-efficient architecture and a 32-bit Tensilica processor.

Cons:
ESP8266:
The ESP8266 is a Wi-Fi SoC that contains all the essential components a user needs to run a Wi-Fi device. The ESP8266 is an inexpensive Wi-Fi enabled microchip that you can add to any microcontroller for wireless connectivity.
ESP8266 is an integrated circuit with 16 GPIO pins and various peripherals such as serial peripheral interface, integrated circuit protocol, analog-to-digital converter.
The ESP8266 has no ethernet and no touch sensor. It has no remote control access and lacks security.
ESP8266 has no encryption or temperature sensor.
ESP32:
The ESP32 is an upgraded version of the ESP8266 with 34 GPIO pins and a 160MHz Xtensa dual-core processor.
The ESP32 features a 32-bit processor, an ultra-low-power coprocessor, and multiple input/output ports, including digital-to-analog converters. ESP32 has a secure IoT platform.
ESP32 provides you with remote control access and a temperature sensor. ESP32 gives you Secure Boot Flash Encryption 1024-bit OTP with PWM (soft)16. The ESP32 has ten touch sensors.
ESP32 is better than ESP8266. It gives you faster processors and lots of memory, enabling you to design larger projects on just one SOC.
ESP32 provides you with reliable and high-tech security. Robust security features are the hallmark of the ESP32. The ESP32 has a solid board, firmware, and peripherals. Computing power also creates a huge fundamental requirement for secure socket layer connections and the IoT world.
ESP32 devices have more GPIOs to handle more available and complex projects. It is more suitable for any situation where the application requires a microcontroller. Many ESP32 boards come with small cameras and are said to be a very powerful board.
ESP32 development is powerful with better security and more memory for projects you can't do in ESP8266.
The modules of ESP8266 can read and process data and control GPIO. It comes with 2.4GHz Wifi in the 802.11 BGN variant and also supports WPA2 encryption.
Efficiently use data processing functions to read digital and analog signals from sensors. Another use is to read complex calculations from adders or multipliers that drive other algorithms.
The module can be used to connect to any nearby network. It can also be used to easily create your own P2P network.
Optimizing WiFi usage helps wirelessly transmit data to nearby routers.
A connection between two ESPs can be established directly even without a P2P network or smartphone.
Understanding the use of IoT modules will help us identify areas where their true potential can be tapped. Some of the areas where this module is essential are:
In conclusion both the ESP32 and the ESP8266 are amazing. When it comes to certain items, sometimes one is more popular than the other. The ESP8266 consumes less power than its competitors, but one has more digital pins than the other. Therefore, you should choose the desired variant.
