NodeMCU ESP8266 V3 Lua CH340 Wi-Fi Development Board

Description

The NodeMCU ESP8266 V3 development board integrates the popular ESP8266 Wi-Fi microcontroller with a CH340G USB-to-TTL serial chip, offering a complete platform for building connected IoT devices. It delivers robust 2.4GHz Wi-Fi with support for common security protocols (WPA/WPA2) and multiple operating modes, allowing it to act as a station, access point, or both simultaneously.

Designed for rapid prototyping, the board breaks out most ESP8266 GPIOs, including digital I/O, PWM, I2C, 1-Wire, and a dedicated analog input channel. Its 4MB flash provides ample space for application code and supports remote OTA updates. The board is compatible with the Arduino IDE using community boards packages, the official Espressif SDK, and the native NodeMCU Lua interpreter for script-based development.
