NodeMCU is an open-source firmware and development kit that is based on the ESP8266 WiFi module. It is designed to provide an easy and affordable way for IoT (Internet of Things) development, and it allows developers to create connected devices quickly and easily.
The NodeMCU development board has the following specifications:
Microcontroller: ESP8266EX
Processor: Tensilica L106 32-bit RISC CPU
Operating Voltage: 3.3V
Clock Speed: 80MHz or 160MHz (overclocked)
Flash Memory: 4MB or 16MB
RAM: 80KB or 160KB
WiFi: 802.11 b/g/n
GPIO: 17
ADC: 1 (0-3.3V)
SPI: 1
I2C: 1
UART: 1
PWM: 1
Power Consumption: 0.9mA in deep sleep mode
Dimensions: 49 x 24.5 x 13mm
In addition to the hardware specifications, NodeMCU also comes with a Lua-based firmware that allows developers to write and upload code to the device using a simple serial interface. The firmware also includes a number of useful libraries and APIs for working with the device's various features, such as its WiFi connectivity, GPIO pins, and more.
