NodeMCU ESP8266 V3 Lua CH340 Wi-Fi Development Board
The NodeMCU ESP8266 V3 is a low-cost Wi-Fi development board featuring the ESP8266 SoC and CH340G USB-to-serial chip, programmable via the Arduino IDE or NodeMCU’s Lua scripting for rapid IoT prototyping.
Features
- Powered by the ESP8266 Wi-Fi SoC with integrated TCP/IP stack for 2.4GHz 802.11 b/g/n connectivity (STA/AP/STA+AP modes).
- Features a stable CH340G USB-to-serial converter for reliable firmware flashing and serial communication across platforms.
- Provides extensive GPIO, PWM, I2C, 1-Wire, and a 10-bit ADC interface for connecting sensors, actuators, and peripherals.
- Includes 4MB of flash memory for storing application code, filesystems, and supports Over-The-Air (OTA) firmware updates.
- Open-source NodeMCU firmware enables event-driven, Lua-based scripting for rapid application development without deep embedded C knowledge.

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.
