The All-new NodeMcu ESP8266 V3 CH340 Wifi Dev. Board isa fast-leading edge low-cost WiFitechnology. Modern high-level mature LUA-based technology. It is an integrated unit with all available resources on board. It is super simple to complement your existingArduinoprojects or any development board that has I/O pins available.
Modern Internet development tools such as Node.js can take advantage of theNodeMCUwith the built-in API to put your idea on the fast track immediately.NodeMCUis built based on the matureESP8266technology to take advantage of the abundant resources available on the web.
The NodeMcu is an open-source firmware and development kit that helps you to prototype your IoT product with a few Lua script lines. The Development Kit is based on ESP8266, integrated GPIO, PWM, IIC, 1- Wire and ADC all in one board.
NodeMCUhas ESP-12-based serial WiFi integrated onboard to provide GPIO, PWM, ADC, I2C, and 1-WIRE resources at your fingertips, built-in USB-TTL serial with super reliable industrial strength CH340 for superior stability on all supported platforms. This module is one of the cheapest available wifi modules on the market. V3 or Version3 is the latest version of this module
