AI Thinker NodeMCU-ESP8266 is an open-source firmware and development kit that helps you
to prototype or build IoT products. It includes firmware that runs on the ESP8266 Wi-Fi SoC
from Espressif Systems, and hardware which is based on the ESP-12 module. The firmware
uses the Lua scripting language. It is based on the eLua project and built on the Espressif
Non-OS SDK for ESP8266.
