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.

What's Included

This kit contains:

• ESP32 development board (with built-in Wi-Fi and Bluetooth)
• Common sensors (temperature, motion, light, etc.)
• LEDs, buzzer, and push buttons
• Jumper wires
• USB cable for power and programming
