Microcontrollers are at the heart of electrical goods that allow consumers to experiment with a variety of powerful projects. Many individuals are interested in purchasing the most efficient microcontrollers available. NODEMCU and Raspberry Pi Pico are the most popular controllers within the tech community.

One of the most prevalent questions among developers is which board they should purchase for their project. We'll go through all of the specifics for both development boards in this post. So let's get this party started.

Overview of NODEMCU with Raspberry Pi Pico

Although both the NODEMCU and Raspberry Pi Pico devices appear to be the identical, they are used for distinct applications and have different capabilities.

The Raspberry Pi Pico is the company's first device based on its own silicon. The RP2040, a Raspberry Pi-designed processor with Dual Core ARM Cortex-M0+ clocked at 133MHz, 256KB RAM, 30 GPIO pins, and a wide range of interface possibilities, is at its core. For code and data storage, the Raspberry Pi Pico has 2MB of inbuilt QSPI Flash memory.

NODEMCU varies from the Raspberry Pi Pico in a number of areas, allowing for the development of new products. The powerful microcontroller ESP8266, single core CPU, 32 bit LX106 architecture, clock speed up to 160MHz, and operating voltage of 3.3 V make up the NODEMCU board.

Access to the Internet

IoT technologies are gaining popularity throughout the world because they make developers' and users' jobs simpler. You can use the microcontroller to send, upload, and receive data, which is a fantastic way to use your product. Raspberry Pi Pico is undoubtedly a fantastic device for consumers who want to create high-tech goods at a low cost, but it lacks internet access. The Raspberry Pi Pico does not come with an inbuilt Wi-Fi module that allows it to connect to the internet or other devices.

NODEMCU has a solution for this problem in the form of the ESP8266 WiFi module, which allows the user to connect to the internet. A user may take use of this feature to make their product more accessible to a large number of people. The NODEMCU may now be used to create IoT apps.

Flash memory and speed

In terms of performance, the Raspberry Pi Pico easily outperforms the NODEMCU. The Raspberry Pi Pico has a dual-core CPU in front of the NODEMCU, which will improve the quality of your project. The Raspberry Pi Pico's 32-bit ARM Cortex M0+ CPU increases the processor's performance, allowing the device to process data quicker than the NODEMCU. NODEMCU is based on the 32-bit LX106, which is suitable for projects but seems slower than the Raspberry Pi Pico.

Another feature worth mentioning is the flash memory on both boards. The Raspberry Pi Pico has two megabytes of flash memory, but the NODEMCU has four megabytes.


For the developer community, extra features like built-in sensors are a dream come true. The temperature sensor on the Raspberry Pi Pico is a fantastic addition for those who want to include it into their projects. The NODEMCU does not include any other sensors that may be utilized in the project, but you can add a temperature sensor to it. If you're new to embedded systems and don't know how to attach the sensor to the board, NODEMCU is a good alternative. Otherwise, the Raspberry Pi Pico is the best solution for temperature sensing.

Final Thoughts

Finally, both the NODEMCU and Raspberry Pi Pico boards are commendable in terms of sophisticated features and specs. It all boils down to your project's requirements and setup.

People should choose Raspberry Pi Pico above NODEMCU if they want a strong CPU and quick working speed. If you are a novice and want to build an IoT product, NODEMCU should be on your shopping list. Another benefit of the NODEMCU is that it may be used as a stand-alone device as well as in conjunction with other controllers.
