Description

NodeMCU simplifies working with the ESP8266 by integrating a USB-to-UART converter, onboard voltage regulation, and easy pin access. This eliminates the complexity of external programmers and unstable power supplies, making it ideal for students, hobbyists, and professionals.

The board supports multiple programming environments, including Arduino IDE, Lua (NodeMCU firmware), and AT commands. With built-in WiFi, it enables direct internet connectivity, web servers, REST APIs, and cloud-based IoT platforms.
