NodeMCU is an open source IoT platform. The term "NodeMCU" by default refers to the firmware rather than the dev kits. The firmware uses the Lua scripting language. It is the 5th design of NodeMCU devkit. This uses [CP2102](https://www.amazon.co.uk/UART-CP2102-Module-Serial-Converter/dp/B00AFRXKFU) as UART bridge, and can flash firmware automatically by using nodemcu-flasher. Also it has a voltage regulator con convert from 5v to 3.3v which is the required by the esp21e module.
