NodeMCU is an open source Lua-based firmware for the ESP8266 WiFi SOC from Espressif and uses an on-module flash-based SPIFFS file system. NodeMCU is implemented in C and is layered on the Espressif NON-OS SDK. The firmware was initially developed as a companion project to the popular ESP8266-based NodeMCU development modules, but the project is now community-supported, and the firmware can now be run on any ESP module.

Features

  • Easy to program wireless node and/or access point
  • Based on Lua 5.1.4 or Lua 5.3 but without debug, io, os and (most of the) math modules
  • Documentation available
  • Asynchronous event-driven programming model
  • More than 70 built-in C modules and close to 20 Lua modules
  • Firmware available with or without floating point support (integer-only uses less memory)
  • LFS support
