The NodeMCU V3 is a breadboard-friendly open-source ESP8266 development kit, armed with the CH340G USB-TTL Serial chip. The CH340 line of chips is notoriously known as the affordable alternative to the CP210x. Whilst cheaper, CH340 is super reliable even in industrial applications
Open-source, Interactive, Programmable, Low cost, Simple, Smart, WI-FI enabled for Arduino-like hardware IOT
Advanced API for hardware IO, which can dramatically reduce the redundant work for configuring and manipulating hardware.
Code like for Arduino, but interactively in Lua script.
NodeJS style network API
Event-driven API for network applications, which facilitates developers writing code running on a 5mm*5mm sized MCU in NodeJS style.
Greatly speed up your IOT application development process.
A great set of tools to develop ESP8266.
NodeMCU is built based on the mature ESP8266 technology to take advantage the abundant resources available on the web.
