ESP8266(NodeMCU) Kit
Overview
The NodeMCU is a compact and low-cost development board based on the ESP8266 Wi-Fi chip. It is widely used in IoT (Internet of Things) projects to connect devices to the internet. The board has built-in Wi-Fi, a USB port, and can be programmed easily using the Arduino IDE.
It is ideal for beginners who want to build smart devices such as Wi-Fi switches, wireless sensors, or simple automation systems.
NodeMCU vs ESP32 – Basic Difference
- NodeMCU is best for simple, single-task Wi-Fi projects.
- ESP32 is more advanced with more GPIO pins, Bluetooth, and faster processing.
- Start with NodeMCU for learning, and upgrade to ESP32 for complex tasks.
