node mcu lua wifi intern based esp8266 ch340

Product Description – NodeMCU Lua WiFi ESP8266

The NodeMCU Lua WiFi ESP8266 Development Board is a low-cost, open-source IoT platform built around the ESP8266 WiFi SoC. It integrates GPIO, PWM, I²C, 1-Wire, and ADC interfaces, making it versatile for connecting sensors and actuators. With built-in USB-to-serial (CP2102 or CH340), it’s plug-and-play for programming and debugging.

Key Features:

• Microcontroller: ESP8266 (ESP-12E/12F module)
• Operating Voltage: 3.3V (on-board regulator)
• Input Voltage: 4.5–10V (via micro-USB or external supply)
• Connectivity: 802.11 b/g/n WiFi with PCB antenna
• Programming: Supports Lua scripting and Arduino IDE
• USB Interface: CP2102 or CH340 USB-to-serial chip
• GPIO Pins: 10+ digital pins (D0–D8), analog input (A0), UART (TX/RX), RST, EN
• Interfaces: PWM, I²C, SPI, 1-Wire, ADC
• Compact Design: Breadboard-friendly, clearly labeled pins

Advantages:

• WiFi-enabled for IoT applications
• Easy to program with Lua or Arduino IDE
• Plug-and-play via micro-USB (no external programmer needed)
• Flexible power options (USB, battery, external supply)
• Open-source firmware with Node.js-style event-driven API

Applications:

• Smart home automation (lights, appliances, sensors)
• Wireless sensor networks
• Remote monitoring systems
• IoT prototypes and embedded solutions
