NodeMcu v3 Lua ESP-12E WIFI Development Board

Description Attachments

The NodeMcu is an open-source board with inbuilt ESP-12E WIFI module. This is not a weakling like the Arduino's, with 512kb of memory and a processor at 40Mhz there is not a shortage of sources. This sign is extremely suitable for starting IoT (Internet of Things) applications. Programming the NodeMcu is slightly different than normal, with the API that looks like NodeJS, this module receives the commands through the LUA scripts that are uploaded.

This concerns version 3 of the NodeMCU series, which is somewhat wider than the previous version and therefore no longer fits neatly on a breadboard. To make this right, an I / O shield has been designed to fit this NodeMCU perfectly. This version contains the CH340G version to save costs instead of the CP2102 serial chip.
