What’s the difference between ESP8266 and ESP32?

Wondering what’s the difference between ESP8266 and ESP32? Keep reading to learn what you get out of ESP8266 or the dual-core ESP32 micro controller.

When it comes to the comparison of ESP8266 and ESP32, there are several key differences that set them apart. Firstly, both chips have a 32-bit processor, but there are variations in their specifications.

Whats the difference between ESP8266 And ESP32?

When delving into the realm of IoT (Internet of Things) development, one often encounters the choice between the ESP8266 and the ESP32, two prominent contenders in the field. Understanding their distinctions is vital in selecting the right chip for your project.

Both chips have a 32-bit processor. The ESP32 is a dual-core 160MHz to 240MHz CPU, whereas the ESP8266 is a single-core processor that runs at 80MHz. These modules come with GPIOs that support various protocols like SPI, I2C, UART, ADC, DAC, and PWM.

In terms of computational power, the ESP32 stands out with its dual-core architecture and higher clock speeds, making it ideal for applications demanding more processing capacity. The ESP8266, on the other hand, caters to simpler projects that require less computational muscle.

Moreover, the ESP32 features Bluetooth and Wi-Fi capabilities, expanding its connectivity options. It’s a valuable choice for applications that necessitate wireless communication alongside processing.

Cost considerations also play a role. The ESP8266, being an older chip, tends to be more budget-friendly. If you’re looking for a cost-effective solution for basic IoT projects, the ESP8266 may be your choice.

Overall, the choice between the ESP8266 and the ESP32 hinges on your project’s requirements. If you need a more potent processor, dual-core performance, and enhanced connectivity, the ESP32 is the way to go. However, if you’re working on a simpler project with budget constraints, the ESP8266 can still deliver reliable performance. It’s all about matching the capabilities of these chips to the specific needs of your IoT project.

The ESP32 is equipped with a dual-core 160MHz to 240MHz CPU, while the ESP8266 features a single-core processor running at 80MHz. This means that the ESP32 can handle more complex tasks and offer better performance than its counterpart.

Another significant distinction lies in the GPIOs provided by these modules. Both the ESP8266 and ESP32 offer GPIOs that support various protocols including SPI, I2C, UART, ADC, DAC, and PWM.

However, the ESP32 tends to have more GPIO pins compared to the ESP8266, which allows for more versatile connectivity options and greater flexibility in project development.

In terms of wireless connectivity, the ESP8266 was initially designed to provide Wi-Fi capabilities, while the ESP32 takes it a step further by offering both Wi-Fi and Bluetooth connectivity. This enables the ESP32 to connect to a wider range of devices and opens up possibilities for more diversified applications.

Additionally, the ESP8266 module typically comes with limited onboard memory, usually around 4MB, making it suitable for smaller, less memory-intensive projects. On the other hand, the ESP32 module offers more memory options with varying sizes, ranging from 4MB up to 16MB. This increased storage capacity gives developers the freedom to work on more data-intensive projects without worrying about running out of memory.

While both the ESP8266 and ESP32 have their own merits, the ESP32 stands out with its dual-core processor, expanded GPIO options, and additional Bluetooth connectivity.

It provides a higher level of performance and versatility, making it a preferred choice for more complex and diverse IoT applications.

However, if you are working on a smaller project with less memory requirements, the ESP8266 module might be a more suitable and cost-effective option.
