ESP8266 NodeMCU V3.0 WiFi Board (ESP-12E)

Overview

The NodeMCU V3.0 development board is built around the ESP8266 ESP-12E module and brings GPIO, PWM, I²C, 1-Wire and ADC together on a single board. That integration is the point: you can drive motors and LEDs, read sensors and talk to Wi-Fi without bolting on extra hardware.

The ESP8266 combines strong performance with very low power consumption, which makes it a natural fit for IoT nodes, smart-home automation and light industrial monitoring. The board ships pre-loaded with NodeMCU firmware, so you can start writing Lua scripts straight away — or reflash it and use the Arduino IDE, MicroPython or the Espressif SDK instead.

Key Features

• All-in-one I/O — GPIO, PWM, I²C, 1-Wire and ADC integrated on one board, no extra breakout needed
• Wi-Fi built in — 2.4 GHz 802.11 b/g/n for connected projects
• Precise control — Hardware PWM for smooth motor, actuator and LED dimming
• Easy sensor integration — 1-Wire support covers temperature sensors, memory chips and similar devices
• Analogue input — On-board ADC converts real-world analogue signals to digital data
• Rapid prototyping — Pre-loaded NodeMCU firmware with Lua scripting; also works with the Arduino IDE and MicroPython
• Low power — Suited to battery-powered and always-on designs
