NodeMCU V3 Lua WIFI Module

NodeMCU V3 Lua WIFI module is based on the widely explored esp8266 System on Chip.

We add an extra 32Mb (Megabit) memory to the NodeMCU V3 Lua WIFI module. This is better for doing significant projects with an extensive library. You do not need to worry about the size of your memory.

NodeMCU V3 Lua combined features of the WI-FI access point and station + microcontroller. The firmware uses the Lua scripting language. The firmware is based on the eLua project and built on the Espressif Non-OS SDK for ESP8266. It uses many open source projects, such as lua-cjson and SPIFFS Due to resource constraints, users need to select the modules relevant to their project and build firmware tailored to their needs. Support for the 32-bit ESP32 has also been implemented.
