The NodeMCU (Node Micro Controller Unit) is an open-source development toolkit and software which lets you test your IOT product with only a few Lua lines of code. It is an open-source interactive Programmable Low-cost Smart Wi-Fi-enabled hardware similar to Arduino. IO The most advanced API available for hardware IO that can drastically simplify the task of controlling and configuring hardware. Create code similar to Arduino however, interactively in Lua script. Nodejs style network API, which is an event-driven API for network-based applications that allows developers to write programs running on a 5-millimeter-by-5-millimeter size MCU using Nodejs style. You can greatly accelerate your IoT development process. Specifications: Ver2.0.
