Difference between ESP32 and ESP8266

ESP32

A versatile Wi-Fi+BT+BLE MCU module called the ESP32 can be utilized for a wide range of applications in electronic parts, from low-power sensor networks to the most demanding networks like those for voice encoding, music streaming, and MP3 decoding. It features a power amplifier, low noise amplifier, filters, and a power management block in addition to the integrated antenna and RF balun. On the printed circuit board, the entire solution takes up the least amount of room. The TSMC 40nm low-power 2.4 GHz dual-mode Wi-Fi and Bluetooth chip on the board has the best power and RF characteristics, is secure and dependable, and can be used in a variety of applications.

ESP8266

The system-on-chip (SOC) ESP8266 is a fully functional or independent WiFi module with an IP/TCP protocol stack. Any microcontroller can be accessed with ESP8266 over a wireless 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 will constantly perform due to its exceptional durability. This is due to its broad operating temperature range, simple. Additionally, it features a 32-bit Tensilica processor and an energy-efficient architecture.

What’s the Difference Between the ESP32 and ESP8266?

ESP8266

The ESP8266 is a Wi-Fi SoC that includes all the vital parts a user requires for a working Wi-Fi device. Any microcontroller can be equipped with the low-cost Wi-fi capable ESP8266 microprocessor to provide wireless connection. The ESP8266 is an integrated circuit with 16 GPIO pins and many peripherals, including an analog-to-digital converter, integrated circuit protocol, and serial peripheral interface. Ethernet and touch sensors are absent from the ESP8266. It lacks security and remote control access. There is no temperature sensor or encryption on the ESP8266.

ESP32

The ESP32 is an improved version of the ESP8266, including 34 GPIO pins and a 160 MHz Xtensa dual-core processor. The ESP32 contains a 32-bit processor, a digital-to-analog converter, several input/output ports, and an ultra-low power coprocessor. A secure IoT platform is provided by ESP32. You have remote control access and a temperature sensor with ESP32. You have the security of PWM (soft)16 and 1024-bit OTP with ESP32’s Secure Boot Flash encryption. Ten touch sensors make up the ESP32.

ESP32 or ESP8266: Which is better?

ESP32 outperforms ESP8266. It gives you a quicker CPU and a substantial amount of memory, enabling the design of fairly complex projects on just one SOC. You get dependable high-tech security from ESP32. One of ESP32’s key advantages is its robust security protections. The board, firmware, and peripherals of the ESP32 are reliable. Processing power also establishes secure socket layer connections, which is a crucial prerequisite for the Internet of Things. With more GPIOs, ESP32 devices can handle more sophisticated and practical tasks. It is more appropriate in every scenario when a microcontroller is needed for an application. Numerous ESP32 development boards are believed to be quite powerful and to include a small camera.Powerful ESP32 programming enables improved security and extra RAM for applications that cannot be run on the ESP8266.
