Similarly one may ask, which microcontroller is used in NodeMCU?

NodeMCU is an open source IoT platform, whose firmware runs on Espressif's SoC Wi-Fi ESP8266, based on the ESP8266 nonOS SDK. Its hardware is based on the ESP-12 module. The scripting language is Lua which allows to use many open source projects like lua-cjson and spiffs.

Secondly, is NodeMCU a microcontroller? The NodeMCU (Node MicroController Unit) is an open source software and hardware development environment that is built around a very inexpensive System-on-a-Chip (SoC) called the ESP8266.

Moreover, what is NodeMCU esp8266 used for?

NodeMCU is an open source development board and firmware based in the widely used ESP8266 -12E WiFi module. It allows you to program the ESP8266 WiFi module with the simple and powerful LUA programming language or Arduino IDE.

What is ESP microcontroller?

The ESP8266 is a low-cost Wi-Fi microchip, with a full TCP/IP stack and microcontroller capability, produced by Espressif Systems in Shanghai, China. This small module allows microcontrollers to connect to a Wi-Fi network and make simple TCP/IP connections using Hayes-style commands.
