About this item

The NodeMCU ESP8266 is an open-source development board and firmware designed for IoT (Internet of Things) applications. It is based on the ESP-12 module, which incorporates the ESP8266 Wi-Fi SoC developed by Espressif Systems. NodeMCU can be programmed using the Lua scripting language or the popular Arduino IDE, making it accessible for both beginners and experienced developers. It supports Wi-Fi connectivity, enabling it to function either as a Wi-Fi hotspot or to connect to existing networks, which is essential for IoT devices. The board features 16 digital I/O pins and one analog input, offering flexibility for interfacing with sensors, actuators, and other peripherals. It also supports communication protocols such as SPI, UART, and I2C, which are widely used in embedded systems. NodeMCU comes equipped with 128 KB of RAM and 4 MB of flash memory, providing ample space for storing programs and data. Its built-in Wi-Fi capabilities, compact design, and power-saving features like Deep Sleep mode make it ideal for battery-operated and remote IoT applications. Typical use cases include smart home automation, wireless sensor networks, and other connected devices that require both computational power and wireless communication.
