NodeMCU

What is it?

NodeMCU is an open-source firmware and development board platform built around ESP8266 and ESP32 microcontrollers. It provides built-in Wi-Fi connectivity and a developer-friendly environment for IoT projects.

What does it do?

NodeMCU allows developers to build connected devices that communicate over Wi-Fi. It supports sensor integration, data transmission, device control, and cloud communication for embedded and IoT applications.

Where is it used?

NodeMCU is widely used in IoT prototypes, smart home systems, automation projects, environmental monitoring, connected sensors, and low-cost embedded solutions.

When & why it emerged

NodeMCU emerged around 2014 as a response to the need for affordable, Wi-Fi–enabled microcontrollers. It simplified IoT development by combining networking capabilities with an easy-to-use programming environment.

Why we use it at Internative

We use NodeMCU for IoT and hardware integration projects that require fast prototyping, low power consumption, and reliable wireless connectivity. It enables rapid iteration from concept to working device.
