What Is The Difference Between ESP32 vs ESP8266. Which Is Better?

The Internet of Things has emerged as a popular subject in both the academic and professional worlds. An improved version of the ESP8266, known as the ESP32, was released in 2016 by the Chinese company Espressif. They introduced the ESP8266 in 2014.

The two inexpensive microcontrollers are frequently utilized in IoT devices. Both features allow for communication with other IoT platforms. The two devices are crucial IoT tools, but they each have a unique purpose and drawbacks. Today, we’ll talk about the two most common microcontrollers in this article.

What is ESP32?

A line of inexpensive power systems on a chip microcontroller is called ESP32. The ESP32 is a more sophisticated model of the ESP8266 family. Espressif Systems is the company that invented and developed the ESP32 family. Dual-core and an ultra-low power co-processor are features of the ESP32. It was created to address the ESP8266’s lack of security.

Pros:  

• ESP32 offers you dual-core 160MHZ to 240MHZ
• You can control and monitor your device with the help of Wi-fi or Bluetooth at a very low price.
• ESP32 offers you more GPIOs
• ESP32 gives you a high speed of 150Mbps.

Cons:

• ESP32 is more expensive than the ESP8266

What is ESP8266?

The ESP8266 is an IP/TCP protocol stack-equipped WiFi module that is a fully functional or self-contained system on a chip (SOC). Any microcontroller can be accessed by the ESP8266 over your WiFi connection.

The hosting of any application or offloading of all WiFi networking tasks is one of the key uses of the ESP8266. Even in tough industrial situations, it can continuously perform and is quite durable.

This is solely due to its wide operating temperature range. Additionally, it features a 32-bit Tensilica processor and an energy-efficient architect

Pros: 

• The robust onboard processing and storage capabilities of the ESP8266 Module make it possible for it to be integrated with sensors and other applications.
• It is very well integrated into the chip. Due to on-chip integration, very little external refer circuitry is required by the user.
• The coexistence interfaces for Bluetooth and VoIP apps on the ESP8266 use APSD. Additionally, it has a self-calibrating radio frequency (RF) that enables it to operate under all circumstances without the need for additional radio frequency components.

Cons:

• ESP8266 does not have Bluetooth connectivity, whereas in ESP32 you can use this feature.
• The GPIO is very less in ESP8266 compared to ESP32.

Comparison Between ESP32 vs ESP8266

ESP8266 vs ESP32: What’s the difference? 

ESP8266

• The ESP8266 is a Wi-fi SoC that includes all the necessary parts for a user to create a working Wi-Fi device. You can add the inexpensive Wi-fi capable ESP8266 microprocessor to any microcontroller to allow wireless connectivity.
• The ESP8266 is an integrated circuit having 16 GPIO pins and a variety of peripherals, including an analogue to digital converter, an integrated circuit protocol, and a serial peripherals interface.
• There is no ethernet or touch sensor on the ESP8266. It is unsecure and does not have remote control access. A temperature sensor or crypto sensor are absent from the ESP8266.

ESP32

• The ESP32 is an upgrade over the ESP8266 and includes 34 GPIO pins along with a 160 MHz Xtensa dual-core processor.
• A 32-bit processor, an ultra-low power co-processor, and several input/output ports, including digital-to-analog converters, are all features of the ESP32. A safe Internet of Things platform is provided by the ESP32.
• You have remote control access and a temperature sensor with the ESP32. The ESP32 provides 1024-bit OTP with PWM (soft) 16-bit Secure Boot Flash Encryption for your security. Ten touch sensors are on the ESP32.

Which is better, the ESP32 vs ESP8266?

ESP8266 is inferior to ESP32 in quality. You may develop significantly bigger projects on just one SOC because to its quicker CPU and adequate memory size.

You can count on ESP32 to give you cutting-edge security. One of ESP32’s specialties is the robust security feature.

The board, firmware, and peripherals of the ESP32 are trustworthy. Secure socket layer connections and other crucial IoT requirements are also made possible by the processor power.

More GPIO on ESP32 devices enables them to deal with usable and complex applications. Every case where a microcontroller is required for an application can benefit from it. Many ESP32 development boards include tiny cameras, and the board is reputed to be quite powerful.

The ESP32 development has the strength to provide improved security and more RAM for applications that are incompatible with the ESP8266.

What is the purpose of this IoT module?

The ESP8266 module has the ability to read, process, and control GPIOs. It has a built-in 802.11 BGN 2.4GHz WiFi that also supports WPA2 encryption. There are numerous uses for it, some of which are given below:

• Effectively reading both digital and analog signals from sensors using its data processing function. Another application is translating intricate adder or multiplier calculations into any other driver algorithm.
• To connect to any nearby network, this module is helpful. Additionally, it can be used to easily build your own P2P network.
• Using WiFi as efficiently as possible is beneficial for sending data wirelessly to a nearby network.
• The connection between two ESPs can be made immediately even in the absence of a P2P network or a smartphone.

Which are its applications? How can I run it?

Knowing how the IoT module is used enables us to identify the areas where its full potential can be realized. The following are some of the places where its module is crucial:

• Using WiFi to triangulate a location.
• Automated outlets in various stores and workshops.
• Industrial security in home and business sectors.
• Wireless monitoring CCTV cameras and sensors that feed data.
